Question about Televison & Video
My guess is this is a power supply problem. It is evident in audio, so it is a problem that effects the circuit. Thus, the main power supply is suspected.
Maybe the electrolytics in the ripple filter are gassy and developing a low impedance path to ground. That would account for the crackling sounds, mabye.
It is the kind of repair that any good tv tech should be able to do. The cost is not great; house call plus maybe $100 or so. That is my best guess.
