In detail: DIY chandelier repair from a real master for the site my.housecope.com.
Savings and design in lighting have brought cutting-edge technology to nearly every home. Many people change their common base chandeliers for economical LED products. Not everyone knows how to repair an LED lamp on their own, especially what parts it consists of inside. How to use the tool in case of breakdown, where to start the whole process. Let's try to figure out in detail what are the breakdowns in the devices and how to repair some LED chandeliers with our own hands.
- Typical breakdowns: partial or complete lack of lighting, short blinking or spontaneous shutdown, failure. Reasons: The temperature has reached above 50 degrees, a break in the contact between the filament itself and the holder, if it is a paid option, and not a lamp one, peeling of the contacts on the board.
- The LED is burnt out, partially or completely. Reason: Overvoltage in the network, capacitor burned out (breakdown). Usually breakage occurs in cheap board options.
- There are additional reasons leading to the failure of the device, namely: a short circuit in the circuit, incorrect connection to the network, non-observance of the device connection diagram during installation.
- Poor soldering of the contacts of the circuit, LEDs to the board, poor fastening of the wires in the base of the lamps. Weak soldering of conductive elements (wires, tires). Reason: Factory defect. The repair of many LED chandeliers with a control panel is carried out for this very reason.
Before repairing the LED light, the fixture must be removed. It will take some tool; thin screwdriver with a flat end, cruciform. If the connection was made using twists, you will need pliers with insulated handles, electrical tape and a multimeter to check the contacts. Tweezers come in handy when working with small parts.

You will need a soldering iron with a thin tip and solder (it is advisable to use a special nozzle). A drill with a 2.5 mm drill., It can also come in handy, disconnect the base of the lamp by drilling out the fasteners. Several thin wires 10 cm long.
Attention! It is forbidden to carry out electrical work without a special protected tool!
Chandeliers appeared with a remote control not so long ago. Few people are familiar with their device. Repairing LED ceiling
x chandeliers need to know the design, just in general terms. Let's take a closer look at what it can consist of.A simple LED chandelier consists of a body, a regulator unit, or a driver. It is used as a voltage rectifier. It contains terminals, or terminal clamps, to which the mains power is connected. Then wires run from the block to the lamps. There can be from one wire, for a regular lamp, up to 12 for a design version of the device.
A more complex version of the product, consists of an antenna, a control unit for the lighting itself, a voltage regulator or several
In multiple blocks that carry out automatic tuning. Raster luminaires can have several drivers and different types of LED elements and lamps. From a specific type of lighting
Why is it necessary to know or find out the design before
start repairing your LED chandelier. The reason is simple, you need to determine where the control units are located, inside the chandelier or in
the lighting element itself, the lamp. Here we need the same LED chandelier circuit.
Repairing an LED chandelier working without a remote control is easier.There is nothing complicated in it, they are assembled according to the same type: one or more diodes (a compact bridge is possible), electrolytes (capacitors), a pair of resistances (resistors), and a coil with a winding. This is the simplest scheme without protection, there are many options for them, but now we will analyze the simplest scheme.
- After removing the lamp, inspect the board for visible defects, broken wires, ohThe absence of such is a good sign.
- Remove the shade or decoration around the lamp, unscrew the lighting elements. Examine the base, burnt spots indicate poor contact. If there are any, try cleaning them with a knife.
- Repack the terminal blocks, or twists, tighten the screws on all parts. Not finding visible defects, we proceed to inspect the lamps. The version of a block luminaire, where relays and lamps are next to each other on a large board, is considered as repairing the lamp described below.
- Do-it-yourself LED chandelier repair begins with determining the location of the breakdown or breakage.
Fix the lamp with a smaller diameter plastic bottle by cutting and inserting the lamp into it.
It is better to supply power with a separate power supply, to the lamp, if it is 12 or 24 volts nominal. All undamaged LEDs in the circuit need to ring the device. But the way is easier, by connecting the lamp to the power supply to carry out simple manipulations
- Alternately close (throw a jumper) the contacts of each LED with tweezers or a wire with stripped and tinned contacts.
- The lamp will light up when you find (close the contacts) on the burned out LED. If this does not happen, see further down the chain.
- Check the board for the cause of burnouts, swelling of capacitors, carefully check the tracks on the regulator board itself. Solder the broken contacts.
You cannot replace the LED with a jumper when there are less than 10 of them in the common circuit, the capacitors will overload, block LEDs will burn out when there are 3 of them in one case. They can be identified by three dark points, inside a yellow or white crystal.
Often the repair of LED chandeliers must be done due to overheating of the matrix itself. First, unscrew the fasteners and visually inspect the inside of the chandelier. Then they carefully try to move the board in place. It is determined whether there is a break in the wires from the control unit, whether the wire is burnt out from overvoltage. If burnt out, solder in place. We check all the details one by one.
Then you will need an original chandelier diagram. Without it, you can only repair the chandelier without a remote control. If there is a remote control unit, the batteries in it are replaced with new elements. LED chandeliers with a control panel are often found; here you will need an exact diagram of the chandelier controller to detect a breakdown.
The chandelier control unit is usually tightly sealed in a shell, and manufacturers draw diagrams on it. Only these are wiring diagrams and lighting elements.
There are also blocks with a collapsible body, then the option is simplified. With a non-collapsible unit, use a tester to call the output signal to the lighting elements (LEDs). In the absence of voltage supply, the reason may be a breakdown of the signal receiver. We disassemble it, visually check the contacts and tracks on the board, the integrity of the parts. If the voltage supply goes to one branch of the lighting, then there is a breakdown in the control unit, and not in the signal receiver itself.
The burned-out part can be evaporated and called, for a start, all the resistances (see the diagram) by putting the OM icon on the device. Then the capacitance of the capacitors, since they have designations, polarity and type are also important when checking.
Designation on the diagram
If a discrepancy is found in the denomination, re-solder.
The chandelier control unit is responsible for the intensity and modes of combustion of the LED elements. Violation of one of the circuits (in the plafond version of the lamp) does not disable the unit, possibly a fuse has blown.
But still, check the blocks, if there are any melted spots on them, there is, replace it with a new one. If the wires are incorrectly connected, only the parts in the power supply are lit. The regulator unit is protected against excessive loads. It can be called according to the scheme.
Many models of regulators, drivers and power supplies for LED luminaires come with cooling heatsinks. They have a seat through which the microcircuit or other control element gives off heat. Most lamps have radiators.
Lack of special grease, thermal paste, the cause of overheating of most (up to 15%) boards and blocks. Unscrew and check if it is applied along the plane of the seat.
The thermal paste is applied in a thin layer over the entire surface of the seat, a large amount will only worsen the heat transfer. By screwing an additional thin aluminum plate to the radiator, it is possible to increase the heat transfer, while the installation is carried out without blocking the main air flows passing through it.
As you can see, there is nothing unusual in the repair of LED ceiling chandeliers, no. It is not so difficult to do it yourself. It takes a little patience, a little practice and a tin of knowledge. Of course, the variety of lamps, lamps and all kinds of chandeliers will not make us bored during the renovation process. But in this number of details, the exact diagram of the LED chandelier and, of course, a great desire will help us figure it out.
You don't have to buy a new LED, it's easy to fix it, just put a small jumper between the contacts. Be sure to remove the remnants of the burnt out part of the LED, clean the board from carbon deposits, it conducts electricity.
The first thing to do before repairing is to inspect the integrity of the tungsten filament (if incandescent lamps are installed). To do this, simply unscrew the light bulb from the socket and look in the light for a visible break, as shown in the photo below. If the thread is intact, this does not mean that the light bulb is working properly. In this case, you need to additionally check the lamp with a tester (multimeter) for an open circuit. All you need to do is fix one probe on the thread of the base, and the other on the end of the light source. If the arrow on the tester's dial twitches, the light bulb is intact and you will have to proceed to a more serious repair of the chandelier with your own hands. The arrow did not move - the lamp is faulty and it will simply have to be replaced with a new one.
If your LED chandelier does not work, then checking the LEDs comes down to the fact that you need to ring them with a tester, perhaps one in the serial circuit has burned out, as a result of which the entire lamp that you are going to repair with your own hands does not light up. Are the bulbs intact, but the chandelier does not light when turned on? We move on, because there can be many more reasons, and, accordingly, repair methods!
If the ceiling lighting stops working and the bulbs are working, you need to check the light switch, because sometimes the contacts burn out in it, as a result of which the current does not flow to the lamp holders. It is quite simple to disassemble a light switch, we talked about this in the corresponding article. After that, you need to visually view the wires at the input and output from the case and the contacts themselves in the form of a hemisphere. If necessary, for repair, you just need to clean the contacts to a metallic color and assemble the case, and then check.
By the way, if you have a chandelier with several lighting groups in your room and half of the bulbs have stopped burning, the problem may be precisely in the two-key or three-key switch, on which the contacts are burnt out. Be sure to read the article, which is useful in this case, on how to repair a light switch.
In addition to visual inspection, it is necessary to check whether the voltage is suitable for the body and whether it goes further along the chain to the chandelier. If there is voltage, it means that the switch is in good order and more complex repairs are needed, which we will talk about further.The voltage can be checked with an ordinary indicator screwdriver - when the tip touches the terminal, the LED in the handle should light up.
Moving on and slowly cutting off all possible causes of the malfunction, it is necessary to check whether the voltage is suitable directly to the chandelier, which is not lit. Here you will have to remove the lamp from the ceiling and open access to the wires removed from the junction box. Again, use a conventional indicator to check if there is voltage, as shown in the photo.
If the voltage comes from the junction box, but the chandelier does not light when the switch is turned on, then it is definitely the cause. Further we will tell you how to repair a lamp with your own hands at home.
So we come to the final part, which describes how to independently repair a chandelier that does not work. Everything is pretty simple here. If the luminaire is ordinary (not LED), you need to disassemble the case and check all the wire connections, as well as the condition of the insulation. A short circuit may have occurred, as a result of which one of the wires burnt out.
You should also check the sockets into which the bulbs are screwed. Very often these circuit elements fail and, as a result, half of the lamps or one of them does not light up. In this case, especially if the products are Chinese, you need to replace the cartridge with a new one, which is clearly not difficult even for a novice electrician!
After such a thorough analysis and repair, the chandelier will most likely work. However, this instruction is only suitable for those conditions where the luminaire is the most common. But what if a chandelier with a remote control, LED or halogen lamps? In this case, the repair is more complicated, which we will briefly discuss below!
So that you can clearly see how to repair a chandelier that does not burn, we have presented several video examples of how to repair the most popular faults:
We talked in more detail about how to check a chandelier in a separate article.
So, now we will consider more rare causes of breakdowns and tell you how to repair a chandelier at home with your own hands, which does not burn, shines poorly or only shines in one mode.
That's all I wanted to tell you about self-repairing ceiling lamps. We hope that now you know what to do if the chandelier is off, and how you can repair the breakdown at home!

A chandelier with a control panel is very convenient to use. With its appearance in the house, the problem of repairing the chandelier with your own hands often arises. At first glance, this seems very difficult. Which is not entirely true. First of all, it must be borne in mind that control of the remote control also involves turning on the chandelier manually.
DIY remote control chandelier repair
It is worth understanding the types of control elements that include lamps (relay with a radio signal receiver) in the following blocks:
- for incandescent and halogen lamps;
- for LED luminaires;
- combined.
The controller is a remote controlled wireless switch that is powered through a conventional switch. A Wireless Switch unit is often installed in chandeliers, with the number of channels from one to four and a voltage of 220 V. A group of lamps of the same type is connected to each channel.
Connection diagram of three groups of lamps with a control panel in the chandelier
The figure above shows a Y-7E type three-channel Wireless Switch controller.First, power is applied to the controller. To do this, the pink wire is connected to phase (L) via a one-button switch, and the black wire to neutral. The device has 2 neutral wires, inside they are interconnected by one terminal. You can swap them.
Power supplies for halogen lamps and LEDs are connected to the controller: each to its own channel (brown, gray and blue wires).
The second black neutral wire of the controller will be common for all power supplies. The output reduced DC voltage from them is supplied to the lamp groups. Chandelier connections are made with insulated plugs.
The halogen lamps in the diagram are connected to each other in parallel, and the LEDs are connected in series.
Halogen lamps are powered by switching voltage converters. Before making repairs with your own hands, first, each lamp is checked separately with a multimeter. If the circuit is not broken, you will have to deal with the reasons for the malfunction of the converters, of which there may be several in one lighting source.
There can be several relays to switch different power. Faults in them are often found in the places where they are soldered into the boards. Over time, the connection may fall off.
The remote control is simple, often disconnected is caused by loss of contact or low battery.
The controller can be controlled from a one-button switch, with sequential switching of lamp groups at each restart.
The control panel is programmed for the controller sold with it. If you take the remote control from a different lamp, it will not work.
Controller complete with remote control
You can install the controller's operability with your own hands if you apply a voltage of 220 V to the power supply unit of each group of lamps. If the chandelier lights up normally, but does not work with the controller, then it is not working properly.
You should look for a replacement part for a faulty one in electronic parts stores. If the price does not suit you, you can find an electrical or radio part in an online store. The cheapest parts are available from suppliers from China. It will take a lot of waiting time. In the standby process, you can ensure the operation of the chandelier from a conventional key or push button switch.
Buyers complain about LED lighting with a remote control for the following reasons:
- The backlight stops working, although the relay can be heard.
- LEDs burn out.
- To light up all the LEDs, you need to press the remote control button several times.
- All lamps are off at the same time.
- The chandelier is not turned off by the remote control.
- After shutdown, the LEDs remain on.
Malfunctions associated with lighting with halogen lamps are as follows:
- failure of the lamp;
- the electronic transformer burns out;
- the controller malfunctions;
- the connecting wires are cut off.
The procedure for checking a chandelier with a control panel in case of its failure:
- Serviceability of electrical wiring. First, access to the terminal block is provided, and then the arrival of phases and working zero is checked. The phases are checked by an indicator, and the neutral wire by a multimeter. The LED chandelier is often connected with one key, and all internal switching is performed by the controller.
- Controller check. The cover is removed from it, and the contents become visible: a receiver board with channel switches.
A working zero is supplied to the black wire from the outlet, and voltage is applied to the red phase wire. Then the indicator checks the potential on the output channels. If the phase does not come, you can try to connect to a free channel, if available. If the device does not work, you will have to buy a new one complete with a control panel. It should be installed in place of the faulty one, and the connections should be repaired by soldering new wires in place of the old ones.
Assembling the chandelier after repair
The faulty controller can be removed and one switch can be used.But this does not apply to LED backlighting, since it is switched by electronics.
If the sequence of switching on the lamps does not suit you, you can change the outputs of the controller.
The control unit has an antenna that does not connect anywhere.
- Checking individual groups... If any of the lighting groups does not work, you must immediately start checking with it. A common mistake of many users is exceeding the connected lamps in terms of power. As a result, the power supply unit (electronic transformer or driver) burns out, and the cartridges melt. In order not to do it yourself once again, you need to correctly calculate the power right away.
Without the skills of working with an electrician, you should not undertake repairs.
The wizard also makes the following checks:
- checking the health of light sources and replacing burned out ones;
- checking and replacing a burned-out controller, driver or transformer;
- repair of electronic boards with replacement of radio components;
- checking and restoring broken wire connections;
- checking if the network connections are correct.
Controller PCB Repair
You can find out about the overhaul of the chandelier, including the replacement of cartridges, from the video below.
Remote control for chandelier and luminaire is becoming common in apartment lighting. The advantages of the new systems are many. In particular, everyone can afford them, and their operation is not particularly difficult.
When it breaks down, some people choose to buy a new lighting fixture. A more practical option, however, is to renovate chandeliers. You can save even more by repairing the lamp yourself. However, in this case, you will need a certain knowledge of the subject and practical skills.
First, they look for the source of the problem, due to which the chandelier came into a malfunctioning state.
If the lamps are working, but the lighting does not work, the first thing to check is the switch. Most often, the cause of the breakdown is in the burned-out contacts, due to which the electricity does not reach the cartridges of the lighting device. After disassembling the switch, inspect the conductors at both the input and output. They also check the status of the contacts. During the repair, the contacts are cleaned to a metallic shine and the case is assembled in the reverse order.
Note! If some of the bulbs in a chandelier with several lighting groups stop turning on, the problem usually lies in the burned out contacts.
In addition to visual inspection, you should check the presence of current supplied to the case. They also check if there is voltage further along the chain - directly to the chandelier. The check is carried out using an indicator screwdriver. The luminaire works normally when, after touching the terminal with a screwdriver, the light diode of the handle lights up.
Note! If the light does not light up after the first press, but turns on again when pressed, the problem is usually with the switch.
It so happens that only one socket does not work. In this case, checking the switch shows its serviceability. The problem lies in the cartridges or the quality of the wiring.
First, the physical integrity of the tungsten filament is checked (we are talking about an incandescent light bulb). They take the lamp out of the socket and check it in the light for a break in the filament. A whole thread indicates serviceability.
You should also test the continuity of the circuit. You will need a multimeter for this. One of the probes of the device is installed on the thread, and the second - on the end of the light source. The movement of the instrument arrow indicates the health of the lamp. An arrow that remains stationary indicates the need to replace the bulb.
In the case of an LED lamp, a multimeter dialing is also carried out. It happens that one of the diodes in the series circuit is out of order, due to which the entire chandelier does not work.
The reason for the lack of glow of the chandelier may be a wiring malfunction. Check for voltage.To do this, dismantle the luminaire in order to gain access to the conductors taken from the junction box. The voltage is checked using an indicator screwdriver.
In the case of old electrical wiring made of aluminum, there is often a violation of the integrity of the wires. If the wire is broken, the contact is broken. Correct the situation by building up an old wire to connect it to the chandelier body. However, a more reliable option is to replace the wiring with a modern one.
Note! If the voltage from the junction box is confirmed, but after pressing the key on the switch, the lamps still do not light up, the problem is in the lamp itself.
To fix a chandelier, they disassemble its case and check the joints between the wires. Also, special attention is paid to the condition of the insulating layer. A common cause of a malfunction is a short circuit, after which one of the conductors burns out.
In addition, lamp holders are subject to mandatory inspection. Especially often Chinese-made elements fail. If the reason is in the cartridge, it cannot be repaired, this part is changed to a new one.
If the ballast capacitor is out of order, the wire leaving it is stripped and a multimeter is connected. A normal voltage level indicates a failure of the series string of lamps. When the voltage deviates from the norm, the capacitor is changed.
Advice! If replacing the lamp does not give a positive result, it is recommended to treat the board with a degreasing solution.
If the chandelier does not turn on, the control relay may be the cause of the problem. The operability of the device is checked with a multimeter with a conductor connected to it from the relay. If a fault is found, replace the relay with a new one.
The above is about the most common malfunctions. However, those who decided to repair the chandelier on their own face others:
- Incompatibility of new lamps with old chandelier models.
- Poor twisting of conductors. Insufficiently twisted conductors prevent proper contact, resulting in lighting problems.
- Inconsistency of the power of the screwed-in lamps with the needs. For example, a chandelier is designed for four 60-watt bulbs, and four 100-watt light sources are installed. For this reason, not only power supplies fail, but also transformers.
- Blown fuses. In modern chandelier cases, fuses are used to break the circuit in the event of a short circuit. Repair work in this case consists in the need to find a blown fuse, dismantle it and install a new component.
- Chandelier break. A break occurs when mechanically acting on the device or in the case of poor-quality suspension (weak fastening).
For the operation of LED devices, transformers are used. To check the health of this component, use a multimeter. If the transformer is serviceable, pay attention to the operation of the diodes. Testing is done with a 9-watt battery and resistor. Each LED is tested sequentially. If a faulty diode is found, a short circuit is performed. At the end of the repair work, the structure is assembled in the reverse order.
When newly installed LED bulbs start flickering, the problem is dimmer incompatibility. Some types of LED light bulbs will not work properly with this device. Only dimmable LED lamps are compatible with it.
The main reason for the malfunction of halogen chandeliers is considered to be poor-quality contacts. To solve the problem, they are cleaned. They also check the correctness of the docking of the conductors. All connections in the junction box and output voltage must be exactly as specified. In the absence of external damage, a multimeter is needed for diagnosis. A measured zero indicates the need to replace the transformer.
Lighting fixtures with a remote control often break.The main signs of failure of such chandeliers:
- despite the transmission of a signal from the remote control, the lamps do not light up;
- individual modes do not function, the chandelier spontaneously turns off;
- the same modes do not work when controlled from the remote control, but they function when switched manually;
- there is flickering, not caused by any human actions, spontaneous switching between modes.
The listed problems are the most common, but a combination of several of them at once is rare. Usually 1 or 2 parts of the remote control chandelier need to be replaced.
The search for a problem in a lamp with a remote control begins with checking the batteries. If new ones are installed, but the chandelier still does not work, the next possible cause of the malfunction is the controller.
Different groups of lamps are most often connected in separate blocks. These elements are connected using a controller. It is common for it to launch only some of the device modules. In this case, you will need to replace it.
It happens that the light does not turn on either with the remote control or when the switch is pressed. In this case, you should pay attention to the number of non-working components. One lamp may burn out. However, when all the bulbs are not working, the probable problem is the electronic transformer. This element is changed to a new one, while working with clean gloves.
The most common problem with a crystal chandelier is the breaking off of structural elements due to mechanical stress. In this case, ordinary glue is not a solution to the problem, since the seam will be noticeable after gluing. Therefore, it is recommended to use a special - silicate glue.
Before gluing the crystal shard, prepare the surface to give it better adhesion. To do this, the crystal is washed with soapy water, and then dried and degreased. Another result of proper surface preparation is that the seam will be less noticeable.
Glue is applied to the crystal, after which the elements are connected and held for some time so that they seize. Then, using a piece of cloth, remove excess glue from the surface of the lighting fixture. After a few hours, the parts will finally stick together and the chandelier will be ready for use as usual.
Before proceeding with the repair of the chandelier, it is imperative that you familiarize yourself with the device of the lamp. Several variants are usually produced at this time.:
- Lamp with incandescent lamps;
- Lamp with halogen lamps;
- Luminaire with LEDs and LED backlighting;
- Lamp with incandescent lamps and LED backlighting;
- Luminaire with halogen lamps and LED lighting.
Incandescent chandeliers are rare. Widely presented are LED lamps with LED illumination and chandeliers with halogen lamps and LED illumination.
Manufacturers put LEDs for the chandelier with a remote control with increased reliability, but they still fail. In order not to buy new lamps home, it is much cheaper to repair yourself.
The controller is a chandelier control unit... The unit contains a radio module that receives commands from the remote control.Depending on the model, the unit contains from two to seven electromagnetic relays, which supply power to the required electronic transformers, and thereby turn on the various lines of LEDs or lamps.
On Led Transforme for LEDs it is written: model lfr807 (66-80), input AC 220-240V, output DC 5V LED (LED supply voltage - 5 volts). The numbers 66-80 indicate the number of LEDs for which this Led Transforme is designed.
Malfunctions associated with chandeliers equipped with a remote control are characteristic. Major breakdowns that are common:
- Does not respond to the remote control;
- Does not respond to a stationary switch;
- A certain number of LEDs or halogen lamps do not light up;
- Several commands are executed from the remote control and stops responding to commands;
- Does not respond to either the remote control or the stationary switch.
There may be several reasons. Take your smartphone, turn on the camera mode, point the remote at the camera and press the buttons. If it works, you will see a bright white blink on the screen. If not, then it needs to be repaired.
You can determine the cause of the malfunction by following these steps:
- Battery check;
- Checking the tracks of the console board;
- Checking and cleaning the contact pads of the board.
If the light device does not respond to the remote control further, take and disassemble it, carefully examine the paths of the printed circuit board, the places of the rations - there may be ring cracks around them, if they are, solder them. Clean the pads.
If the remote control works, then the reason is in the chandelier control controller... Remove the chandelier, take out the controller box, disassemble it and you will see the RF receiver board. Check all the capacitors on the board and the contacts of the rations, it is advisable to replace all the capacitors, since their capacitance decreases over time, and they leak. Check the contacts near the photocell, they are often lost, if necessary - solder. Check the Chinese photocell for cracks.
If all the detected problems are eliminated, and the RF receiver does not work, then the RF receiver microcircuit is out of order. Replace IC or buy a new RF receiver.
If all modes work from a stationary switch, and the selected modes are triggered from a distance, and then the light element stops responding to commands, then the problem is in the control controller board. It contains metal-ceramic capacitors, which resemble plump pads - and they must be replaced.
If the chandelier is switched on from the remote control and does not respond to the stationary switch, this means that the control controller is working properly and the electronic transformers are also working. Otherwise, it would not work from the remote control, provided that the remote control and the control unit are in good working order.... It is necessary to take a multimeter and ring all the connections of the switch with the controller unit, having previously de-energized everything. Find the break and fix it.
If halogen lamps are used, check the electronic transformers to which they are connected.Then check the lamps themselves: they are usually connected in parallel and can be easily called with a multimeter. Find the faulty one and replace it.
If the chandelier does not work either from the control panel or from a stationary switch, most likely the chandelier control unit is out of order... Usually, the chandelier control unit performs its purpose very reliably, but due to voltage drops, the control unit microcircuit breaks down, the conductive tracks on the board burn out. Open the unit by holding the board with one hand. Take a magnifying glass in your other hand, with the help of which you carefully examine the metallized paths for damage and microcracks. Damaged items can be repaired.
Diagnostics and repair of LED chandeliers with a control panel does not cause any particular difficulties. You can save a significant amount of money by repairing the chandelier yourself without the help of a specialist.
