Do-it-yourself casio synthesizer repair

Repair of the CASIO CTK-530 synthesizer - before starting to repair the synthesizer yourself, you must first make a thorough diagnosis of the device. A diagnostic inspection is performed to identify the nature of the malfunction and its location. This is most important in cases in which the synthesizer simply does not turn on, although visual defects are not visible.

When a faulty unit is found in the device, the faulty part is identified and replaced with a known good one. After making sure that everything is done correctly, you can start setting up and testing the device using the service programs. However, you need to warn: if you have little experience in repairing complex equipment of this purpose, then it is best to turn to professional specialists. Lack of skills and certain nuances in the repair of equipment can lead to an undesirable result.

Different devices fall into our service center. As a rule, these are smartphones and laptops, system units of stationary computers and stereos, and once there was even a rocking chair for a baby.

But for the first time we have a synthesizer as a guest. This is an amateur, but very advanced for its level, Casio LK80 instrument. Its main feature is a unique teaching system, which functions due to the backlighting of the keys (the name of the LK model stands for Lighting Keyboard, which means "glowing keys" in English).

The essence of this system is that the synthesizer plays popular melodies stored in its memory, highlighting the necessary keys. And, after a few workouts, you can already start playing on your own. However, in this case, music training was suspended due to the fact that the synthesizer stopped turning on. So he got to us.

The master of the service center "We'll fix everything!" Repair synthesizer begins with diagnostics - the external power supply is checked, since there was an assumption that there was no voltage supply to the device. However, it turned out to be in working order, the voltage is present at the power connector plug. We proceed to disassemble the case. After opening it, no damage or burnout was visually revealed, all the plumes were connected tightly.

The only problematic point found during visual inspection was the presence of dust particles, which could interfere with the normal operation of the device. However, a cursory examination did not reveal any problems.

In the photo below, you can see dust particles on the heatsink of the amplifier chip.

In order to check the functionality of the boards (there are three of them - the motherboard, which ensures the operation of the display and the amplifier board), it was decided to remove them. The first in line is the amplifier. We unscrew the fasteners.

After dismantling the amplifier board, the master calls its contacts - everything is in order with them, the signal passes.

Next in line is the display board. But at this moment, the specialist of the service center has an assumption that due to the contamination of the case with dust and the general condition of the instrument, problems may be caused by poor contact of the power button.Indeed, it turned out that there is oxide on the copper contact of the switch and the adjacent volume control tracks, which prevents the normal passage of the signal, moreover, under the partially hollow rubber power button inside there is a certain amount of dust, which also interferes with good contact.

After cleaning all contacts and removing dust, the power button is put back in place, there is a pause for a few seconds before checking it (did it work or not?), The button is pressed ... And - everything works!

Rejoicing at the successful solution of the problem, the master played a small fragment of the victory march on an already working synthesizer.

The sound is great, all keys work - synthesizer repair completed. For prophylaxis, the contacts of the remaining control keys were also cleaned.

So, the cause of the Casio LK80 malfunction was trivial - there was no contact on the switch button, and no complicated repairs were required to fix it. Now the instrument is working, its owner will play beautiful melodies on it again, and her children will be able to continue learning music. And all this is due to the professionals of the service center "We'll Fix It!", Who carry out high-quality and prompt repair of musical instruments. And to the list of services provided by us, the repair of synthesizers was added.

Is your TV, radio, mobile phone or kettle broken? And you want to create a new topic about this in this forum?

First of all, think about this: imagine that your father / son / brother has an appendicitis pain and you know from the symptoms that it is just appendicitis, but there is no experience of cutting it out, as well as the tool. And you turn on your computer, access the Internet on a medical site with the question: "Help to cut out appendicitis." Do you understand the absurdity of the whole situation? Even if they answer you, it is worth considering factors such as the patient's diabetes, allergies to anesthesia and other medical nuances. I think no one does this in real life and will risk trusting the life of their loved ones with advice from the Internet.

The same is in the repair of radio equipment, although of course these are all the material benefits of modern civilization and in case of unsuccessful repairs, you can always buy a new LCD TV, cell phone, iPAD or computer. And for the repair of such equipment, at least it is necessary to have the appropriate measuring (oscilloscope, multimeter, generator, etc.) and soldering equipment (hairdryer, SMD-hot tweezers, etc.), a schematic diagram, not to mention the necessary knowledge and repair experience.

Let's consider a situation if you are a beginner / advanced radio amateur soldering all sorts of electronic gizmos and having some of the necessary tools. You create an appropriate topic on the repair forum with a short description of “patient symptoms”, ie. for example “Samsung LE40R81B TV does not turn on”. So what? Yes, there can be a lot of reasons for not switching on - from malfunctions in the power system, problems with the processor or flashing firmware in the EEPROM memory.
More advanced users can find the blackened element on the board and attach a photo to the post. However, keep in mind that you replace this radio element with the same one - it is not a fact that your equipment will work. As a rule, something caused the combustion of this element and it could “pull” a couple of other elements along with it, not to mention the fact that it is quite difficult for a non-professional to find a burned-out m / s. Plus, in modern equipment, SMD radio elements are almost universally used, soldering which with an ESPN-40 soldering iron or a Chinese 60-Watt soldering iron you risk overheating the board, peeling tracks, etc. The subsequent restoration of which will be very, very problematic.

The purpose of this post is not any PR of repair shops, but I want to convey to you that sometimes self-repair can be more expensive than taking it to a professional workshop. Although, of course, this is your money and what is better or more risky is up to you.

If you nevertheless decide that you are able to repair the radio equipment on your own, then when creating a post, be sure to indicate the full name of the device, modification, year of manufacture, country of origin and other detailed information. If there is a diagram, then attach it to the post or give a link to the source. Write down how long the symptoms have been manifesting, whether there were surges in the supply voltage network, whether there was a repair before that, what was done, what was checked, voltage measurements, oscillograms, etc. From a photo of a motherboard, as a rule, there is little sense, from a photo of a motherboard taken on a mobile phone there is no sense at all. Telepaths live in other forums.
Before creating a post, be sure to use the search on the forum and on the Internet. Read the relevant topics in the subsections, perhaps your problem is typical and has already been discussed. Be sure to read the article Repair strategy

The format of your post should be as follows:

Topics with the title “Help fix the Sony TV” with the content “broken” and a couple of blurred photos of the unscrewed back cover, taken with the 7th iPhone, at night, with a resolution of 8000x6000 pixels are immediately deleted. The more information you post about the breakdown, the more chances you will get a competent answer. Understand that the forum is a system of gratuitous mutual assistance for solving problems and if you are dismissive of writing your post and do not follow the above tips, then the answers to it will be appropriate, if anyone wants to answer at all. Also keep in mind that no one should answer instantly or during, say, a day, no need to write after 2 hours “That no one can help”, etc. In this case, the topic will be deleted immediately.
You should make every effort to find a breakdown on your own before you get stumped and decide to go to the forum. If you outline the entire process of finding a breakdown in your topic, then the chance of getting help from a highly qualified specialist will be very great.

If you decide to take your broken equipment to the nearest workshop, but do not know where, then perhaps our online cartographic service will help you: workshops on the map (on the left, press all buttons except “Workshops”). You can leave and view user reviews for workshops.

For repairmen and workshops: you can add your services to the map. Find your object on the map from the satellite and click on it with the left mouse button. In the field “Object type:” do not forget to change to “Equipment repair”. Adding is absolutely free! All objects are checked and moderated. A discussion of the service is here.

It is advisable to use an oscilloscope to check the hold time of log.0 at the reset inputs of each of the microcircuits (HG52E35P, HG51B155, TC74HC174AP) from the moment the DVDD is powered on. The active reset level is low. Held in the process of charging the capacitor through the resistor. There is a delay, very short.
Also check the reliability of resetting the CPU itself on the HD6433298A (LSI2) microcircuit at the moment the power plug is inserted.

Next, check if a clock frequency of 10 MHz is issued from pin 7 of the CPU, if it passes, when the power button is turned on, through the IC7 chip to pin 12 (CKI) of the HG52E35 (LSI6) chip. Check if there is a clock signal from pin 2 of the CPU (LSI2) and if it goes to the CLOCK input (pin 9) of IC6.
Check if the CPU, after turning on the power by the button, issues polling signals of the block of buttons and indication - lines KO0-KO5, KI0-KI7, whether there are short circuits in the wires that are between the boards, whether there is any "sunken" button or something else on the board of the button block.
Is there a log. 1 on legs 8, 15, 19 CPU (LSI2). Are there any signals on the address lines A0-A14 of the CPU and on its data lines D0-D7?
Are there any signals being issued along the RD, WR lines, did they arrive as intended to the microcircuits ..

There are no datasheets in the internet on CPU, DSP and RAM.

This forum is not intended for searching keyboard players!
For this there is a special forum SEARCH GROUP / MUSICIANS

On the PSR-R300, the On / Off button only works for turning on. The press is clear.
When the synthesizer is on, pressing it does nothing.

Turning on Yamaha with the extreme right “C” clamped did not help.
Tell me what needs to be done?

drmorgan , good day! I have not come across a similar one. I think a byte copy of the hard disk might help. Yours may have started to “crumble”. I can't say exactly how Triton will behave, but for various techniques I have met two scenarios: 1) the donor disk fits any similar size, 2) the donor disk should be with the same number of bytes (not just 2GB, for example, but 2,147,483 760 bytes) apparently the buffer size is critical for firmware.

Astemir the instrument WON'T TURN OFF? This is the first time I come across.

> Hello everyone! I have a Roland EXR-3! The other day I had him literally!))) Faced such a trawl! I tried to download a firmware update up to 1.03! And accidentally kept another combination (Function + 3) instead of (Function + 2). Kasyak !! now, when turned on, the display is on, but there is no information! Keys don't play! now, instead of the version number (holding the Function + 1 button + turn on) the version has a creeping line with letters and hieroglyphs and! DRAM Test -OK! Flash Test -OK! Did the firmware fly off the tunnels? Has anyone encountered such symptoms? Write your opinions! It's just that Ronald might fall off because of the buttons !! Although considering that he has not been “Made in Japan” for a long time, there is nothing to be surprised at.

Have you tried doing a factory reset? In theory, if the firmware did not get up, then you can roll back to its original state.

Yes, simply, it's trite to try to repeat the procedure with the correct buttons. In theory, the hotkeys should work, since this is all hardwired into the backup rom of your device at the hardware level, specifically so that you can downgrade or upgrade the operating system.

In this case, contact Roland technical support. They should be more accurate.

Good afternoon. I am engaged repairing Casio synthesizers in Ryazan for over 10 years... At one time, I even managed to work as a service engineer in the official authorized Casio service center in Ryazan for electronic musical instruments.

It would seem that there is an official service in Ryazan, why else would there be private craftsmen? As a rule, the official Casio service has a whole bunch of authorizations for various equipment, including laptops, tablets, digital equipment, household appliances, etc. And all service repairs or non-warranty repairs of Casio in Ryazan are made on a leftover basis. Typically, this repair is done modularly. That is, replacing a board with a board or an assembly for the entire assembly + the time spent on delivery and ordering spare parts may exceed all reasonable limits. Therefore, as practice shows. The official service center for Casio in Ryazan, with great difficulty, solves the problem of finding and delivering the original power supply unit for the Casio synthesizer or digital piano in Ryazan.
I - Human - Sergofan come to the rescue in this situation, repair of Casio synthesizers.

The synthesizer is broken and you do not hear anything, or instead of the sounds that caress your ears, you hear a strange grinding sound from under the keys. Let's see what could break in your favorite instrument.

The synthesizer will no longer turn on or turn on, but the sound is distorted, most likely your instrument has problems with the external power supply or plug / socket. Replacing this element requires some professional experience, because it is not easy to find parts for a synthesizer in Ryazan in stores and fit them specifically to your model. The stabilizers / converters on the board could have burned out, but in any case, you need to open the tool and measure the voltage at the test points.

Repair of the synthesizer Casio Wk-3300

Why did the keys start sticking? Everything is simple, perhaps you or your children before playing another home masterpiece, you dined on delicious sausages, did not wash your hands and touch the keys with oily fingers, but even a minimal touch is enough for the fat to get into the contact network and “write wasted” to the keys of the synthesizer.It just so happened from antiquity that musical instruments are played with clean hands, especially Casio synthesizers and digital pianos are anxious to this.

I will carefully remove the adhering dirt with a special cleaning agent and restore the conductive keyboard connection with a graphite pencil or conductive grease or scraps of conductive tape. Probably, you faced a similar situation when the TV remote control stopped working, especially curious ones even climbed inside and tried to wipe all this greasy disgrace with alcohol, I do not argue who it helped. And someone just threw out the old "broken remote control" and bought a new one, since the price for them is low. The situation is different with the keys on the synthesizer, if you are not distinguished by accuracy and have done this disgusting act in relation to your favorite instrument - you were too lazy to wash your hands before playing it, but do not disassemble the instrument yourself! Do not try to clean the rubber bands of the keyboard yourself, as you risk being left without a synthesizer at all. You better trust me.

Dismantling and cleaning the keys of the Casio synthesizer in Ryazan

Another unpleasant situation when you suddenly discover that your Casio synthesizer has defects in the keyboard or keys and requires their inevitable replacement. Do not worry and do not get off your feet in search of original spare parts for Casio synthesizers. Firstly, they are not sold in regular stores, and secondly, for models older than 10 years, Casio ceases to produce and release spare parts. This is a stupid policy of the capitalist world - you know, it stimulates new sales, purchases of a new Casio synthesizer instead of a half-hour repair of an old and capable instrument. In these cases, the world is not without kind people and all original spare parts can be bought on the Ebay site from Western usurers. If you contact me, I will help you find, order and install original or suitable spare parts for Casio synthesizers.

Repair of Casio digital piano in Ryazan

The musical equipment is pleasant to use, but difficult to repair, especially when it is a Japanese Casio synthesizer!
The speaker systems (speakers) of the synthesizer themselves are the least likely to break down. The second most popular are faults from the sound amplifier, as a rule, it is a two-channel integrated circuit of the TDA series, or the contacts of the output jack's headphone simply stick. But the most common problem is a malfunction of the sound processor or digital generator, which is responsible for the formation of a sound wave in the bowels of the synthesizer. Eliminating the first two is not exactly a difficult task. Repairing the digital part of the synthesizer is more problematic but amenable to a solution.

Casio Synthesizer Keyboard Rubber Replacement

This is an equally serious problem that must be resolved! You turn on the synthesizer, and the display is white (blue) and does not load - this is a clear sign that your synthesizer has problems with the digital part. First of all, the Casio synthesizer repairman will always open the "patient" in order to make the correct diagnosis, check the voltage at the output from the stabilizers and control points, if at least one of them is "wrong", you will not get melodies and songs. First of all, you need to reset the instrument to factory settings, you can read how to do this in the instructions for synthesizers. The second solution is to solder radio components, restore oxidized contacts in the digital and analog parts of the instrument.

We try to make the forum not only informative, but also convenient for finding information.
Let's keep it clean and informational together!
It is not difficult, you only need to adhere to a few simple rules.

Synthesizer - an electronic musical instrument that creates (synthesizes) sound using one or more generators of sound waves. The required sound is achieved by changing the properties of the electrical signal (in analog synthesizers) or by adjusting the parameters of the central processor (in digital synthesizers). A synthesizer made in the form of a body with a keyboard is called a keyboard synthesizer. A synthesizer in the form of a body without a keyboard is called a synthesizer module and is controlled from a MIDI keyboard or other device, such as a MIDI guitar. In case a keyboard synthesizer is equipped with a built-in sequencer, it is called a workstation.A synthesizer in the form of a computer program using a universal sound card for scoring and standard input-output means (computer keyboard, mouse, monitor) is called a software synthesizer.

However, this is not so important. Contact the ASC.

The problem with “wiggling contact” of the plug is most likely an existing non-contact between the plug and the printed circuit board of the power supply. There are two reasons for such non-contacts: the first is a defect in the soldering of the contact during assembly; the second is mechanical damage (including simple frequent twitching of the plug when moving, installing, etc.). In addition to the power supply unit, but much less common, on devices with a power button in the form of a slider, the graphite coating is worn out. Both problems are solvable
