PS50Q97HD

[tv john]

hI guys, customer complained of an int.slight screeching noise when warm (PIC OK),I soldered regs on power pcb and it lasted a week. Her description makes me think of a picture contrast fault, because it seems ok on a dvd and playstation. On euras I found also that ZDX801 could be d/j. Any one had this before, and where is ZDX801 ?

Thanks  John
