Keypad repair ?

I recall I saw a simple solution of fixing the rubber keys on TV remote which have the carbon part on the bottom.. But it has completely gone out of my head..
Basically the volume up button does not work on the remote any more :roll: I know there is the keypad fix stuff but that is £15 and id only use a tiny bit, not worth it.
My only thought is maybe trying to heat up carbon area to see if it will re-amalgamate without destroying the rubber..:shrug:
Anyone any ideas on how to simply fix it ?

Only with carbon conductive paint.
Some of these rubber mats have the carbon impregnated within the surface. I think the carbon on the surface oxidises and leaves the surface non-conductive. Washing with an organic solvent just makes things worse.
Other rubber mats just have carbon paint on them which corrodes or gets rubbed off (as my Zero 1 mat did).

Might be as simple as pulling apart and cleaning. Had problems with our Sky remote and there was some kind of liquid inside so I cleaned it IPA and that did the trick.
Trouble is, some have carbon traces on the PCB and they wear out quickly and also are susceptible to being slightly washed out by IPA so care is needed.
I wouldn't try heating the carbon area, you may damage it. Carbon paint all the way if cleaning fails.

Yeah the pain is more expensive than a new remote. Only problem is the new ones are "universal" so its pretty huge remove just to change the volume on the sound bar :(

An MG Chemical carbon paint pen is £17 and will last ages though.

Suppose the simple fix is just to swap the left and volume up button around as the side buttons are never used anyway.

Oddly the carbon looks fine,, so just going to clean it all up with a bit of IPA and see what happens...
