I have an AV3000 for over 2 years.
I encountered the same problems a lot guys before me encountered - the coating on the buttons has worn and i have to press really hard for it to function.
I've bought a "Leitsilber L100 conducting silver", cleaned the buttom of the problematic buttons and applied the liquid. I've waited a whole night for it to dry.
The whole thing worked for a week or so until the substance started to crumble and i got back to suare one. I think its because the substance is used to repair damaged electronic circles and not meant to withstand rubbing. Have i done anything wrong?
I've seen a keypad repair kit:
[Link: replacementremotes.com]Did anyone use it? Is it different from the stuff i used?
I read several guys recommended Loctite Rear Window Defogger repair kit. How much time does it last? Is this the same matearial i used?
A new RC costs something like 75$ nowdays. How much does a new membrane cost and will it last long?
Is this only Sony's problem?
