Remote control repair

With prolonged and intensive use, radio remote controls begin to develop a characteristic malfunction. The remote control buttons 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 operation of the remote control, you can carefully disassemble the remote control, 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 remote control, we will need scissors, a knife, tweezers, Monolith glue and cigarette foil.

tools for repair

Remove the batteries from the remote control. Use a knife to carefully separate the remote control into two halves. The halves of the remote control are usually fixed with latches like this.

open the remote control

Next, remove the board and the block of rubber buttons. Use a damp cloth to remove dirt.

We cut squares from foil to the size of the contact pads.

foil squares

Drop a little glue onto the conductive coating and, taking the square with tweezers, glue it.

glue the foil

Our remote control has five buttons that are not used. 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.

This method restored the functionality of many remote controls of various radio equipment. A repeated defect appears after about a year. You can restore the operation of the buttons again by tearing off the old foil and gluing a new one. And one more piece of advice. To check the operation of the remote control, you need to point the lens of any digital camera at the infrared Light-emitting diode remote control and press any button. If Light-emitting diode blinks, then we can assume with great confidence that the remote control is working properly.

remote control works

If we don’t see blinking, then the remote control is faulty.

    ring the foil before you start working with the remote control! Cigarette foil often does not conduct current, aluminum is applied to the paper with a *mesh* or dots.

    Good day to all!

    I struggled with the TV remote control for a long time, the buttons only worked every now and then.

    After reading it, I rang the cigarette foil and literally in 5 minutes restored all the non-functioning buttons.

    A big THANK YOU to the author!!! wink

    I propose to slightly improve the method of gluing foil (from paper-based candies) to the rubber contacts of the remote control. More than once I tried to glue with different types of adhesives, but over time everything fell off. Rubber, and especially graphite-containing rubber, does not hold glue. But, I found a way. Using a stationery knife, we make 3-4 shallow (about 5...1 mm) cuts on each site. No effort required, cuts great. Next, take the epoxy resin and mix 2-3 grams with an acid hardener. This volume is more than enough. Using a needle, apply small droplets of resin to the cut contact pads and wait 3-5 minutes. During this time, the resin, due to its high fluidity, penetrates into the cuts and fills them. There is no need to fiddle with anything, it will flow in there on its own. Next, we place pre-cut squares or rounds of foil on the remaining drops and barely press them to the base of the rubber bands. You CANNOT press down with your finger, otherwise the remaining resin will fall from your finger onto other areas and after polymerization there will be no contact on them. We wait 5-8 hours until it completely “dries”. To control the polymer, we do not throw away what the resin was diluted on/in, but use it as a “tester” of hardening. After time, the resin has some residual elasticity and does not break when pressing buttons, and the adhesive strength is top class. Over time, the aluminum will wear off rather than peel off. At the end, you can (should) press a little with an elastic band on the thick fabric to give a spherical shape to the edges of the foil. We assemble the remote control, or whatever you have, and enjoy the light presses.Good luck everyone.

    This remote control was repaired by me at work, as they say, in the field. Material that was at hand. It's been over a year now and all the buttons are working perfectly. Although before the repair there were offers from work colleagues to buy a new remote control. Thank you all for your feedback and comments.

    The foil falls off after a week (the glue dries out - it crumbles), the conductive paste is smeared, mix with a silicate base - complex components are needed... the best and proven method: QUILTE THE WORKING SURFACE WITH COPPER WIRE LIKE A THREAD (3-4 stitches are enough for a century)!

    There is a much simpler method. Degrease and thoroughly wipe conductive coatings with a pencil lead. 100% result!

    I use keyboard film for repairs; I have been doing repairs this way for over 15 years. It’s impossible to describe in detail in the comments, so I’ll share a link to my master class in one forum.

    The idea is good, but in more than 30 years I have never had a case where a simple and effective remedy did not help - thoroughly wash the remote control body and then wipe the board and rubber band with the buttons with alcohol. Withstands this several times, in any case, the remote control of the TV purchased in the early 90s still works, although the TV itself is gone ;)

    First you should pay attention to the cleanliness of the contact surfaces. I always first wash the button block with water and washing powder, and wipe the board with a dry or alcohol-moistened cloth.In the vast majority of cases, this turns out to be enough.
