Do-it-yourself Samsung TV remote control repair

In detail: do-it-yourself repair of the Samsung TV remote control from a real master for the site my.housecope.com.

The TV does not turn on with remote control Or don't you switch channels, don't adjust the volume, and the other buttons work fine? Such symptoms malfunctions of the remote control familiar to almost everyone. This malfunction of the remote control is the most common and has been going on since the appearance of the remotes themselves, but the manufacturers have not taken any radical measures to eliminate them. With almost 100% certainty, the cause of such a malfunction is the erasure or contamination of the conductive layer of the contact buttons. There are two resumptions of the remote control in this case:

- First - do not bother and buy a new remote control. It is worth noting that by purchasing a cheap (not original) remote control, you run the risk of encountering the same or another breakdown in the first month. Therefore, if you decide to change the remote control, then, if possible, buy the original remote control and not in the “sharashkin cantor”. This will save you nerves and money.

- Second - repair the remote control yourself. It does not require knowledge of electronics and is available to anyone, regardless of gender and age. Apart from the battery, which you also remove from the remote control, there is no “dangerous” electricity "in the remote control. Even if something does not work out, then the first method always remains in stock, and the money for this will require rather modest ones. But why pay if you can do everything yourself in 15-20 minutes, besides, any new remote control will have the same fate and the experience of the first repair will not be in vain.

It is worth noting that with rare exceptions, repair shops do not carry out such a restoration, or the cost will be comparable to the price of a new remote control. If you decide - then do it yourself, everything is simple, but this article will help you.

At the beginning, let's dwell on

Diagnostics of malfunction of the TV remote control, tuner, air conditioner or any other equipment

- If the device does not turn on with the remote control and no buttons work, then replace the batteries first. With weak batteries, it is possible to respond to the buttons once or twice in a row, then it does not respond, after some time (20-30 minutes) it reacts again once or twice. This also indicates worn out batteries that need to be replaced. If this does not help, then there is a malfunction in the electronics. Further, depending on your qualifications and desires, you decide on an independent repair. This is not our case and requires knowledge of electronics to repair.

- Checking the remote control with a digital camera.

To do this, just point the remote control at the camera lens or cell phone camera and hold the button. At this point, take a picture of the remote control without the flash. If the remote control or button is working, then the photo will show a bright white spot in the place of the IR LED. If the glow is visible in the photo, then the reason is most likely in the receiver located in the TV or other equipment from which your remote control. Conclusion about the repair, as in the first paragraph.

- If they do not work, or work (respond to pressing) with 2-10 attempts, only a few buttons, the most frequently used, then this is our case. Next, we will consider ways to eliminate this malfunction of the remote control.

All remote controls have a similar device. Main components:

- Frame. Consists of two halves, glued or twisted.

- Printed circuit board. The board contains a small microcircuit, some more radioelements, an infrared LED, contacts of the battery compartment and a contact pad in the form of conductive tracks.

- Rubberized pad with buttons.

At the very beginning, we take out the batteries, then we look in the battery cavity for the presence of fastening screws. They can be found under the stickers. Swipe over the sticker with a screwdriver, if it sells somewhere, then there is a screw under it. Examine the entire case for screws. If there is, unscrew everything and divide the case into two halves. In addition to the screws, the case can be latched. If there are no screws, then the whole case is assembled only with latches. It happens that it is additionally glued, but do not panic, everything is sorted out.

We take any knife and gently push the tip into the slot in the middle of the case and try to push the halves apart until a click appears. A click indicates that one of the latches has opened. It is important here to find and disengage the first latch, the rest will go easier. Try to do everything carefully so as not to break the latches, and even if you break one or two, it does not matter, the remote control will not close worse from this, in extreme cases it is easily glued with a drop of any superglue. You can also separate it with two thin screwdrivers, or combine a knife and a screwdriver.

If you are disassembling the remote control for the first time, it is preferable to work with a knife and a screwdriver. First, slip the tip of the screwdriver into the slot, between the halves of the case and, slowly moving the screwdriver along the case, look for the first latch. As soon as you find it, snap it off, but leave the screwdriver stuck near the latch, and then continue to work with the tip of the knife. When you reach the next latch with the knife, you can insert a second screwdriver and continue moving with the tip of the knife, or continue moving with the first screwdriver. In general, do as you like.

Then take out the board and the rubber pad with buttons. The battery compartment has slots into which the spring contacts of the batteries are inserted. Before removing the printed circuit board, remember how they fit in the grooves so that there are no questions during assembly. In most cases, these contact springs are soldered onto the board and do not fit otherwise.

General remarks.

Before reconnecting the conductive layer of the buttons, it is recommended to simply clean it first. Sometimes contamination is visible with the naked eye.

Quite often, the entire space where the rubber base with buttons is located is filled with a transparent sticky and viscous liquid that looks like an epoxy resin, only without a hardener. This liquid is smeared with a neat thin layer, in places with small droplets. This sticky liquid is everywhere. On the top and bottom of the rubber base of the buttons, on the top of the case with sockets for buttons. The top of the PCB with contact pads is also smeared with this glue ...

The origin of this glue is a matter of debate and even controversy in repair circles. Some say that it is grease from the fingers, others that it is fumes from batteries. But why, then, the lower part of the board, where there are no parts, is not covered with these fumes?

The most likely version seems to be that these sticky compounds come from the very rubber base itself. The rubber seems to be sweating, releasing plasticizers from itself, which indicates a violation of the technology for the production of rubber products. The only question that arises is why there are so many such substandard products? This is observed in almost every remote control when such a malfunction occurs.

It should be cleaned with soap or other detergent, but not alcohol, acetone, etc., which can lead to a complete failure of the remote control.
A good result can be obtained by washing the board and gum with buttons with not very hot water, preferably with the use of dishwashing detergent or laundry soap.

Rinse gently with a soft cloth, dabbing with motions, so as not to erase the graphite coating. It is quite good if, before washing off the snotty deposits, the parts of the disassembled remote control lie for some time, about 20 ... 30 minutes, in a detergent solution.After rinsing, do not wipe it off, but wait until the parts are dry and only then assemble the remote control. You can use a hair dryer to speed up drying.

Do not completely assemble the remote control, put the buttons, insert the batteries and check the operation. If everything works, collect and use. If the malfunction remains, proceed to the second stage of recovery. In some cases, you can skip flushing and go straight to recovery. Intuition to help you.

Using glue, carefully glue the pieces of foil onto the pads of the "mat". Foil can be taken from sweets (clean), chocolates, or better from a pack of cigarettes. Aluminum foil with a paper base from cigarette packs is glued quite reliably and simply with any glue of the "Moment" type or superglue from small tubes. Piglets can be made both square and round. You can use a hole punch of a suitable diameter. The result should look something like this.

A 5-7 cm long strip of double-sided tape must be glued to the foil, cut off the edges of the foil where there is no tape. Then we “pass” the foil with adhesive tape through the hole punch as many times as we need to repair the buttons or use scissors. You can also use a broken telescopic antenna. A link of a suitable diameter is taken and circles are carved on the glass. When the circles are ready, glue them on the non-working areas of the remote control buttons. You don't have to bother with circles, but cut out squares.

Additionally, you can carefully use a sharp blade to cut the conductive rubber layer from the buttons in front of the sticker. Typically this is a layer of about 0.5-1.0 mm.

You will need a copper wire with a diameter of 0.2-0.4. Using a hammer, flatten it on any anvil with an interval of about 1 cm. Schematic designation (“——” This is a wire, “O” is a place for flattening) (—- O —- O —- O—-) we cut off the element (—– )

we stick the left end of the element into the button, you can next to the button, bend the flattened part of the element (—– O) over the conductive rubber

If fixed well, then this option is quite durable.

A simpler option is a metal staple bracket. Bend-shorten to the size of the contact pad and press it into the rubber in such a position that when the button is pressed, the bracket closes the contacts on the board.

Another option for repairing the remote control is to smear the buttons with conductive adhesives and varnishes, for example, "Kontaktol" or "Ellast". There are also many different opinions regarding this method, which is not yet clear better. Apparently, everything is simple: whoever succeeds well, he praises and vice versa.

Ready-made repair kits are sold specifically for repairing remote controls. They are cheap - the main thing is to find. The bag contains a tube of glue and round graphite-coated rubber patches. Just spread and glue where you need to. There are even instructions on how to glue.

A more modern version of the repair kit is self-adhesive patch. Everything is quite simple here. In such cases, it will not hurt to wipe the rubber buttons with alcohol or other solvent.

All options are functional and tested in practice. Choose whichever you like best. Good luck.

Almost all modern household appliances have remote controls, so when this small device breaks down, users experience some discomfort. We will tell you how easy it is to repair the TV remote control at home with your own hands, without calling the master from the service. Many people just go to the store and buy a new remote control, but in the event of a slight breakdown, everything can be fixed by yourself.

The statistics of remote control repairs in service centers states that the most common breakdowns or device failures are as follows:

  • breakdown of important controls and housing due to falls from different heights or other mechanical influences;
  • sometimes some of the buttons do not work the console, and the rest perform their functions properly;
  • frequently used buttons do not function or only work when pressed very hard;
  • The TV's remote control works only from a very close distance.

It is not difficult to identify the cause, but you need to know the procedure for the upcoming repair, which directly depends on the breakdown that has occurred, sometimes it is cheaper to buy a new remote control than to revive the old one.

Important! When the remote control buttons for your TV do not work, before proceeding with the repair, try to insert new batteries - in 80% the remote control will work in the same mode.Such simple actions will help to revive even the Smart TV remote control.

In this section, we will tell you in detail how to disassemble and repair the TV remote control in each case.

When users often drop the TV remote control, serious breakdowns occur inside the device, and repairs in this case will be quite difficult - without a soldering iron, it will hardly be possible to restore the bounced solder. To make sure that the board is to blame, and you need to rewire something - there is original way of checking, you just need to make sure that the batteries are in working order. This method checks absolutely any remote control, regardless of its brand - Samsung, Philips or LG, because the principle of operation is identical for everyone.

In any digital camera and on mobile phones, including, there is infrared emitter, we check the TV remote control with it:

  • turn on the camera on the mobile phone;
  • direct the remote control to the camera window, while bringing the mobile phone as close as possible, press any key on the remote control;
  • if the remote control emits a signal, a large red dot will appear on the device screen.

Its presence indicates that the board is working, and you just need to check all the buttons. If the point is absent - 100% something happened in the control board, you need to get it out and visually look for the cause of the breakdown.

We remove the batteries, then carefully and without effort we disconnect the halves of the remote control from the TV, after unscrewing the fastening screws. If the latches are installed, then we use a thin screwdriver, but without fanatical efforts, so as not to break their delicate design.

In this case, repair of the remote control can only be done by a person who has certain knowledge and skills in working with a soldering iron - it is better for an ordinary user not to fit into such a delicate device. As a result of frequent dropping, the LED mount may break off, the battery terminal block may come off, or the quartz resonator may fail. The first two breakdowns can be identified visually. To make sure that the resonator - a small box with contacts soldered to it - is in good working order - you need to gently shake the entire device, if you hear a rustle, then you need to change it.

Users sometimes ask the question: how to repair the TV remote control when some of the buttons have stopped working. During operation, the inside of the TV remote control could get wet due to high humidity in the room or accidentally spilled drink. According to experts, a state of oil condensation has developed inside the product - the accumulated dust has combined with water vapor, which greatly complicates the correct operation of the buttons when pressed. Such a repair of the remote control buttons can be done independently: special skills are not required here, you only need accuracy and patience to clean the device for controlling the TV.

  1. We carefully disassemble the remote control.
  2. We wipe the board with a cotton swab, soaked in alcohol - in such a simple way, the plaque of dirt and moisture, which can close the contacts, is removed. Efforts are not worth it - the product is quite delicate.
  3. In the same way we wipe the contact rubber pads of the buttons.
  4. We clean the spring contacts of the batteries, if there are traces of oxidation, then they are removed with a fine sandpaper.
  5. After cleaning, we give time to dry all the elements and assemble the device.

Note to users! Remotes made in China stop working after cleaning with alcohol! This is especially true for the Samsung model of the Chinese assembly.

To cleanse such delicate products from internal dirt, you must use soap and water - with the help of the solution, all the insides are gently wiped, then they must be washed with plain water at room temperature, wiped off with paper towels, and left to dry. After final drying, assemble the structure and check its functionality.

Repair of remotes, when frequently used buttons have worn off their contact bottom cover, is done at home. To do this, you will need the following materials:

  • foil, which has a paper base on the back - this is necessary for high-quality gluing, a similar package from a cigarette pack is very suitable for this;
  • good glue type "Moment»Or with a conductive silicone base.

In retail, there is a special glue for such needs, but it costs more than the remote control itself, which in our case is unprofitable for repairs.

The repair technique is simple.

  1. We disassemble the remote control and remove the rubber part.
  2. We glue foil circles or squares on the bottom surface of non-working buttons.

In stores you can find special kits, where there are buttons with a conductive coating and a very strong glue for attaching them. This kit can come in handy for repairs to restore your remote control.

If the TV remote control is broken because it was accidentally stepped on, then repairing it will cost you many times more than purchasing a new one. The market will pick up an exact copy of your remote control, even if you have a TV with Smart TV, which does not require any setup - insert the batteries and use it. Until the purchase is made, you can do with manual control: turning on the TV without a remote control is quite simple, but unlocking it is more difficult.

Experts assure that almost any user can perform minor repairs of any TV remote control: it is possible to replace batteries or stick new conductive spare wheels from a repair kit without having certain knowledge and skills. In case of complex breakdowns, you should contact the masters from the service, if the repair is more expensive than the remote control itself, then it is easier to purchase a new one.

We offer home craftsmen to watch this video, which clearly shows the repair of the remote control:

If the buttons on the TV remote control do not work, first, no matter how trite it sounds, check the batteries by replacing them with new ones. The situation has not changed? Try turning on the camera on your mobile phone, aiming it at the front diode and seeing if it blinks when you press the buttons. The fact is that a person cannot see infrared radiation, but the camera captures it, as can be seen in the photo.

Does the diode not blink? So, in order to repair the TV remote control with your own hands, you need to disassemble it and check the condition inside. First, pull out the batteries and check if there are any screws under them that hold the case together, then visually inspect the back cover for screws. After unscrewing all the fastening parts, insert a straight screwdriver at the junction of the two parts of the case and separate them, as shown in the photo below.

Some models of TV remotes are fastened with ordinary latches, i.e. without screws. To disassemble such a case, it is enough to simply separate the connecting parts with a straight screwdriver. This must be done carefully so as not to damage or scratch the plastic!

So, the case is disassembled, now you need to carefully inspect all the details yourself: the board, the contact pads of the buttons, spring contacts for batteries, an emitting diode, conductive tracks and ceramic quartz.

Let's start with the spring contacts for the batteries. Check if the contact from the microcircuit is unsoldered, if everything is in order, go ahead. No - take a soldering iron and solder it carefully.By the way, you can make a soldering iron yourself if you don't have a normal tool at hand.

Also, look at the state of the spring itself, which is in contact with the battery, it may be heavily soiled and rusted. If so, to repair the TV remote control with your own hands, you need to clean it with sandpaper.

The next possible reason is the contamination of the contacts of the buttons with oily dirt. The appearance of this dirt - long use of the device, as a result of which the condensation of fat from the skin of the hands settles on the contact pads. If these pads are rubber, you must wipe them well with a swab dipped in alcohol or wet wipes. Also wipe the board as perhaps dirt is shorting out the contacts, as a result of which the buttons on the TV remote control do not work.

If the contacts are graphite-coated, the malfunction may be that this coating has worn off over time. Repairing the TV remote control in this case is quite simple - you need to take the foil from the chocolate bar, cut into small squares and glue the paper side to the contacts.

By the way, if the buttons on the TV remote control are not pressed well, you need to press hard on them, the cause of the malfunction is the same and you can repair the device by cleaning the contacts or restoring them.

If only some of the buttons do not work, and then the most necessary ones - turning on the TV, switching the volume or channels, then most likely the graphite spraying has worn out on them!

Also faulty ceramic quartz can be a possible cause of breakage. If the remote control does not work after a fall, then by 95% you can be sure that this element of the circuit has broken. It is quite simple to determine this on your own - shake the board, and if a rustle is heard from the quartz, it means that it is not functioning. Repair in this case comes down to replacing the quartz.

If you can turn off / on the TV, change programs or sound only at close range, either the dead batteries or the diode are to blame. In the latter case, you can check the health of the emitting diode at home by visual inspection of the soldering, as well as by checking through the phone camera. If the diode is really hooked, it will also have to be replaced.

Well, the last malfunction is damage to the contact tracks. If you see cracks on the microcircuit, then repairs will be inappropriate here, and it is best to just buy a new remote control device.

You can clearly see how to repair some of the faults yourself in the video examples below:
