Hi,
I have faced this problem with many old electronic equipment like TV, VCR, CD player, HIFI system. As they get old the button logic seems to get mixed up!! say if you press the volume up button the player responds as if you have pressed the volume down button or any other button located close to the volume up button. I am presuming that this should becouse of aging of solder joints. But could it be because of other problem? Or could it be an indication of some eminent problem?

Hello asimov,

Can you specify which old electronic equipment it is.
For example VCR type DAWOO has this strange reactions. In fact it is due to a rotating switch which gets soiled. This switch has to be cleaned with alcohol en then the issue disappears. Some inexpensive equipment has no logical processor but a rotating switch.
I don't know for tv... Maybe bad elco's...
If you have an issue google can give you a lot of solutions. The issue of the rotating switch was found on it. Thomsom VCR can have the same trouble, with a such rotating switch.
I hope my answer is useful.
With kind regard

Hi,
I have a pnasonic Hi Fi system, purchased sometime in 2001, The buttons on the front panel are giving this problem. But I have faced similar problem with other old equipment like my car stereo, my personal CD player.
