tv john:
This samsung lcd starts as usual, after a short period starts hissing and crackling through speakers.
When the noises get louder the video blanks and set goes to standby. When it cools down the process star ts again. Thought about audio amp,but customer won't let it out of his house.

Any ideas John.
