REMOTE CONTROL REPAIR

Send

With prolonged and intensive operation, the remote control of the radio equipment begins to manifest a characteristic malfunction. The buttons on the remote control stop responding to pressing. This happens due to contamination of the contact pads of the board and rubber buttons, or due to wear of the conductive coating of the buttons. To restore the remote control, you can carefully disassemble the remote, clean the pads and buttons with a damp cloth, and apply a little conductive glue to the buttons. But there is another way to restore the remote control. This is to use pieces of foil glued to conductive rubber bands.
To repair the console, we need scissors, a knife, tweezers, Monolith glue and cigarette foil.

We remove the batteries from the remote control. With a knife, carefully divide the remote into two halves. The halves of the remote control are usually fixed with these latches.

Next, remove the board and block of rubber buttons. Using a wet towel, we clean them from contamination.
From foil we cut squares to the size of the contact pads.

We put a little glue on the conductive coating and, taking a small square with tweezers, glue it.

Our remote control does not use five buttons. Therefore, it is not necessary to glue foil on them.

Next, we assemble the remote control. We insert the batteries, observing the polarity, and check the operation of all buttons.

Using this method, the operability of many remote controllers of various radio equipment was restored. A repeated defect appears after about a year. It will restore the buttons again by tearing off the old foil and gluing a new one. And one more tip. To check the operation of the remote control, you need to direct the lens of any digital camera to the infrared LED of the remote control and press any button. If the LED blinks, then with great confidence we can assume that the remote control is working.
