Question about Flat Panel Televisions
I have a Phillips 42PF320A/37 Plasma TV (Chassis # BP2.3U) that has a full screen picture and good sound but it has a red noise or flicker that is superimposed on the bottom half of the screen. (See Photo)
I have replaced Plasma TV circuit boards before but am not sure which to replace this time. I suspect the Main Logic board (LJ41-03387A) but I also am not sure about the Signal Processing board because it contains the VIPER circuitry.
Thanks in advance.
Have simular problem w/50pf7321d/37.
Red noise cloud on black parts in center of pic.
FiOS box switched out. Can turn color down,
set color to cool, brightness down way low or use ECO setting and get minor relief. But, that's a poor pic.
I'd replace board if I could figure which.
Panel replacement can't be found...

The old saying that a pictures is worth a thousand words could have been looking at this one... If the lower screen had been streaked in B&W or bands ran completely through the picture Old Drummer I would suspect the logic board also but that's lower y-board failure.
