I pulled a remote out of a drawer that hasn't been used in a long

the remote to flash, but 1 doesn't flash.

I opened it up and blew on it. It is still broke.

The black button material on the end of each key is conductive, it
bridges the two printed patterns on the printed wiring board when you
press the key. Have you tried interchanging a good key with the bad
one to see if the conductive material on the end of the key has worn
off from use or is dirty?. I have fixed several remotes by cleaning
off the dirt that was on the surface of the PWB and on the surface of
the key, which kept the key from electrically bridging the two
intermingled fingers on the pwb.
+1 on that. I love this stuff from Radio shack.

Now wait just a minute!!!! He hasn't tried WD-40 yet. :-)


You beat me to it.

Deoxit is a great product. I can't see it eating corrosion, but otherwise
it's a good cleaner and protectant.

Again, CRC 2-26 available at the home depot, among others is a great
contact enhancer, but does leave some light lube.

MCM electronics, among others used to sell kits to refurbish remote pads.

Expensive-- but worth the price of a can the first time it save an
electronic gadget. I bought my first can to fix a tuning knob on
the TV wee were playing Atari games with. I just bought my second
can last year.
It eats corrosion, gum, gook on any electrical contact. I've cleaned
up remotes, cables of all descriptions, MP3 players, phones. . . .
