Question about Protron PLTV-4250 42 in. LCD Television
Let verify first to narrow down to where the problem can be, attach the powered PC speakers to the Audio Line out RCA jacks to see if you get the crackling sound there also, if you do, then the problem is in the sound processor circuit. Please post back what you find. If not, then the power section is bad. If you can live with sound from the Powered speakers, you may want to keep on using it that way, just muted the speakers in the sound setup menu, otherwise the repair bill can be in the $200~300 range.
