How to repair the remote control?
Sequencing
If the buttons do not work on the TV remote control, for starters, no matter how trivial it sounds, check the batteries by replacing them with new ones. The situation has not changed? Try to turn on the camera on your mobile phone, point it at the diode in front and see if it blinks when you press the buttons. The fact is that a person cannot see infrared radiation, but the camera fixes it, as can be seen in the photo.
Does the diode not blink? So, in order to repair the remote control from the TV with your own hands, you need to disassemble it and check the condition inside. First, pull out the batteries and check if there are screws under them that hold the case in place, then make a visual inspection of the back cover for screws. Having unscrewed all the fastening parts, insert a straight screwdriver at the junction of the two parts of the case and disconnect 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, simply disconnect 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 examine all the details yourself: the board, the contact pads of the buttons, the spring contacts for the batteries, the emitting diode, the conductive paths and ceramic quartz.
Let's start with the spring contacts for the batteries. Check if the contact from the microcircuit has decayed, if everything is in order, go ahead. No - take a soldering iron and gently solder it. By the way, you canDIY soldering ironif 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 very dirty and rusty. If so, to repair the remote control from the TV with your own hands, you need to clean it with sandpaper.
The next possible reason is the contamination of the button contacts with oily dirt. The appearance of this dirt is a long time using the device, as a result of which condensate of fat from the skin of the hands settles on the contact pads. If these rubber pads need to be wiped well with a swab dipped in alcohol, or with wet wipes. Wipe the board as well. possibly dirt closes the contacts, as a result of which the buttons on the remote control from the TV do not work.
If the contacts are with graphite spraying, the malfunction may be that this spraying has worn off over time. Repairing the remote control from the TV 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 remote control from the TV 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 buttons are to turn on the TV, switch the volume or channels, then most likely the graphite deposition has worn out!
A possible cause of the breakdown may be a malfunction of ceramic quartz. If the remote control does not work after a fall, then by 95% you can be sure that this circuit element has broken. It is quite simple to determine it yourself - shake the board, and if a rustle is heard from quartz, it means that it does not function. Repair in this case comes down to replacing quartz.
If you can turn the TV off / on, switch programs or sound only at close range, either the dead batteries or the diode are to blame. In the latter case, it is possible to check the operability of the emitting diode at home by visual inspection of the soldering, as well as by checking through the phone’s 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 in the microcircuit, then repair will not be appropriate here, and it’s best to just buy a new remote control.
You can clearly see how to repair some of the faults yourself in the video examples below:
What else is important to know?
If the buttons on the TV remote control do not work, you can also repair them with your own hands, buying a repair kit in ready-made stains and glue. Of course, it costs a lot, but one such kit is enough to repair 3-4 devices.
You can also, instead of gluing patches, just drop a special glue called “contact” onto the fat-free rubber contacts of the buttons. The only problem is that it costs quite a lot, but still such a glue is useful to a beginner electrician at home in order to repair other electrical appliances.
In conclusion, I would like to note - if your remote control from the TV sticks or does not work due to contamination of the buttons, after thorough cleaning, we recommend wrapping the device with a bag (even special ones are sold) or a thin film. In this case, the fat will not get on the chip and pads.
That's all I wanted to tell you about why the remote control from the TV does not work and how to repair it with your own hands at home! We hope that the instruction with photos and video examples was useful for you!

Well done and well done, I knew everything about quartz, that after a blow, it makes a noise inside and is no longer fit, I didn’t know how good guys are !!! Although pulses through the camera are visible on all buttons.
If the diode is functioning when the buttons are pressed and the lamp on the TV duplicates the pressing on the remote control, but there is no action ??? What is the problem?
Most likely the problem is in the TV itself. Here you already need a wizard call.
Hello, the deod is constantly on. what to do?
only one HOME button on smart tv Philips doesn’t work ??? What to do?
Probably worn graphite spraying on it. It needs to be restored, they wrote about this in the article.
After the fall the remote control stopped working for me. I disassembled it, checked the contacts, everything is fine. But there is no ceramic quartz on my remote control. Samsung smart TV. What can be done
Thank you very much for your help and tips. On the Toshiba remote, several buttons stopped working at once, thanks to your instructions, I disassembled it, and it turned out that between several contacts there was a coating of fat, wiped with alcohol and a bang !!! The remote control is working again !!! Collected - everything is OK! Thank!
My buttons have changed places, the menu - exit, decrease - turn off and so on. What to do?
Disassemble the remote control and clean the entire board with a rudiment of alcohol.
Gentlemen, the situation is as follows: I connected the phone as a magic remote control to the lg 49uj630v TV, after which my native remote control stopped working. Moreover, if in a tight place to bring the remote control to the IR - receiver of the TV, then it works every other time. Moreover, the situation with the “Mi Remote” application on the phone is exactly the same, and the “lg webOS magic remote” application works fine. Most likely the application “lg webOS magic remote” is connected to the TV via bluetooth, and “Mi is the remote” via IR.
Thank you for the article and the videos especially helped) I had to google what nulling is, but these are little things in life 😂
Thanks a lot! Dismantled, wiped everything with a wet towel and ... voila! It all worked!
BEST SITE !!!! I WILL GET FIVE STARS !!! HELPED TO REPAIR THE REMOTE UNDER HOME
A good article, everything is true, except for the restoration of spraying and foil. In this case, just like replacing quartz, it’s easier to buy a new remote control for 200-300 r
Everything is much simpler - no need to glue the foil, - disassemble the remote control, turn the rubber coating upside down, take a simple pencil (preferably soft or hard soft), rub the pencil on the sandpaper (or bar) with a graphite rod (stylus) and then dipping the tip of the stylus into the formed graphite the dust will cover it with the inner surface of the rubber buttons (the side that is in contact with the board). Assemble the remote. ALL. Now it will work like new!
The remote control works without the upper case, I put the case in place, does not work. What is the reason?
Unfortunately I believed a man who says that with a zero skin you can fix everything, they say rubber is conductive and all this can withstand. There it was. Several movements of the sandpaper and all the keys that worked worked stopped working. The inside of the contacts is visible with a spray coating and is very thin. Now you need to stick some conductive. Ohm, which after 3 days will fall off. Thanks again to him. Degenerate.
Toothbrush with soap, we clean the rubber band with buttons, as well as the body. We wash away with a stream of warm water. After everything we dry in the sun and collect it back. Attention! Do not use alcohol for cleaning! You will partially erase the conductive layer. After several such wipes, firstly, the conductive varnish on the buttons comes off, and secondly, the rubber of the buttons collapses and becomes sticky. For many years I did not know this and stupidly ditched several remotes.
