For remote controls that have been properly cleaned out and still
don't work like new, I understand some conductive material needs to be
coated onto the circuit board contacts on the inside of the pad
buttons. Reviewing web discussions of this I wonder if a good approach
may be to mix graphite in silicone glue and lightly coat the surface
of the pad's underside. Anyone tried this or have a thought on it?
Others have used electrically conductive paint (e.g., that purchased
at auto supply stores to reconduct broken rear window defrost
circuits) but that would not seem to be as flexible as silicone glue
with conductive material mixed in it. I did read where someone mixed
finely shredded copper (from pipe) with thinly diluted white glue and
it worked well (but for how long?). It would seem that the latter
approach would be better if silicone glue was used, as it is more
flexible. What ye think?


There is conductive paint for just this purpose at electronics stores.
Ford Electronics in Fullerton, CA had some. I saw it there. I think
they ship.

FWIW I tried the aluminum foil glued on, I didn't have 100% success.
Since I wanted a 100% working remote control any less than 100% is
failure. I haven't tried the paint.


Aqudag won't work, however the Chemtronics remote repair kit works
great. Chuck
How about Aqua-dag? I wonder if it is still available? Used to apply a
conductive coating inside and outside of CRT envelopes.
