Question about Televison & Video
Why some channels scramble we have cable tv, have replaced the main power board.
Posted by Anonymous on
If not the cable source then the MAIN pcb (not power pcb) controls all tuning. If you're using a cable box & some channels good/some channels scrambled, then is a cable issue.
