We have a magnavox model #TS2552 chassis 25p503.It cracks twice volume drops down and a few seconds later sound comes back to normal. Some days set is ok.never did it in shop.Changed IC240 & IC230 the audio outputs.supply voltages are right on.But never had a chance to check when it cracks.Philips tech line has no record of this problem.Any help will be welcome.
