A large number of modern household appliances are remotely controlled. Any of us experiences severe discomfort if the remote control from the TV, air conditioner or other equipment, which we are used to controlling remotely, suddenly breaks down. But in fact, there is no particular reason for concern if the remote control does not work, since most of these malfunctions can be eliminated if you make the right repair yourself. As a last resort, if, nevertheless, it was not possible to solve the problem and the remote control does not work, there is always a way out - to purchase a new remote control device.
You press the buttons - and no reaction
The complexity of DIY repair directly depends on the type of damage. It is often quite enough to simply clean the device from accumulated dirt, sometimes soldering of the elements is necessary.
Very often such a problem arises when you press the buttons, but there is no reaction: the TV channels do not switch, the sound level does not change either. Why isn't the remote working? In this case, the TV and the remote control do not establish communication. The problem could be caused by the following:
- Complete discharge of batteries;
- Multiple falls onto a hard surface.
If the remote control does not turn on due to discharged batteries, then no repairs are required at all. In this case, you just need to change the batteries and everything works again. If this is the second option, then fixing the remote control will be much more difficult. Most likely, there was a break in some soldering points in the device circuit, because of this, the device does not turn on.
How to find a fault
What to do first when the remote is found not to work? To check activity, you need a mobile phone. Activate the camera on your mobile device. Point the remote at the camera as you would for a photo and try pressing any of the buttons. If the signal is present, you will see a luminous dot on the screen of the mobile device. This indicates that the remote control turns on and responds to commands.
If you did not see the signal, then the remote control really does not work. You need to disassemble the remote control device, examine the board and make repairs. Disassembly must be done with great care to prevent damage to the case and not leave scratches on it. To begin with, take out the batteries and inspect the niche in which they are placed. When you find the screws, unscrew them. The latched remote control is carefully opened with a screwdriver or a plastic card.
For a better study of the board, small details, you can use a magnifying glass. A person with experience in handling soldering equipment will be able to make the repair qualitatively. The most common damage to the board is a falling off LED, a loose contact pad of batteries, damage to a quartz resonator. Shake the board slightly and if you hear a rustle, then the resonator is damaged from the inside, and it must be replaced. The part looks like a small box soldered to the board.In the radio components market, its price is low.
When the remote control does not turn on, a diagnosis must be performed first. Now you know how to check it for a malfunction, and now it will not be too much effort to fix the remote control. You can proceed directly to the repair.

One part of the buttons works, the other does not
Why do some buttons turn on and others don't? Sometimes it happens that the remote control gets dirty. Drinks are spilled on it, or it is in a room with high humidity, and oil sludge begins to condense inside the device. In this case, the remote control can be easily repaired by hand.
- Disassemble, remove the board and wipe gently with cotton wool moistened with alcohol. Remove plaque.
- Spray the key pads and housing with alcohol to disinfect. Do not rub with pressure to avoid disrupting the contacts.
On the network, you can find reviews of visitors who claim that after treatment with alcohol, the console ceases to function at all, that is, it does not turn on. Yes, some Chinese designs may actually fail. To avoid this problem, try a solution of water and dish detergent instead of alcohol. Dissolve the product in water, wet the sponge and gently wipe off all the parts you need.
Clean the spring contact. A heavily soiled spring is cleaned with sandpaper or the hard side of a sponge. After the parts are completely dry, you can start assembling. This way, you do the repair yourself and everything works as usual.

Frequently used buttons do not work
In the remote control, which has served its owner for a long time, the most used buttons begin to wear out from constant pressing. Rather, the conductive coating is rubbed off, and the device stops picking up the signal, in fact, it simply does not turn on. You can do it yourself if the remote control device does not work for this reason. Disassemble the device and take out the rubber base. Glue pieces of foil to the back of the buttons, you can take it from chocolate, which has paper on one side and foil on the other. Use silicone glue or Moment for gluing. Special conductive adhesive can be purchased to provide contact, but the cost is much higher.
In radio parts stores, it is possible to purchase kits that include both glue and coated buttons. These repair kits contain everything you need to do it yourself to fix a remote control that won't turn on. Just instead of worn out elements, you need to put new ones on glue. The device works better with new buttons.
Unrecoverable or lost remote controls can be replaced. Universal remote controls will come to your aid. If you purchase a new remote control similar to the old one, there will be no need to configure it.
