Some things come to mind:

I have seem some 5" CRT TV with strange sympton, and resulted to be only the ON/OFF switch, with intermitent good/bad and resistive contact.

Maybe a bad cap near to sweep dedicated IC, or bad solder?

Or, the IC...

In any case, track down the 12V input and check the switch; they can love to have bad habits
