It's probably a tact switch problem, something we call in the industry awindex syndrome. The tact switches, depending on the ones effected, can turn the tv on/off by itself, channel +/- at will or in your case control the volume.
Tact switches are not expensive to replace but a bit difficult to get to if you're not trained. They are at the very front of the board - looking from the back - and some disassembly may be necessary to take the main board out.
A reputable shop wouldn't charge much do fix this problem, switches are about a dollar a piece.
Good Luck

    It's no doubt tact switches.. I think you'll find that surrounding temp plays a role in what's being affected.

    Good Luck!

Low volume on playback

The volume control on the TV does not affect the recording. However, if you were recording from a set top box, and you turned the volume down on the box and not the TV, then this would cause the problem you describe.

If this is the case, then try to keep the STB volume at maximum and only use the TV volume control.

Also, some DVD players and VCRs have a lower output than the standard TV tuner, so an increase in volume is usually needed.

You might want to try some test recordings to see what happens.
