Plasma TV Fault

I"ve had the TV for about 15mths and have noticed a red speckle that appears on black background. The speckle type of appearance seems to travel from one side of the screen to the other that is only visible when there is a black background

Color Speckling in Dark Part of Picture


the set needs to have an adjustment in the panel voltages. this must be done by a qualified tech. the panel has now gotten it's full aging and now needs to be adjusted. this adjustment does not need to be adjusted again after this has been done.

Colorful "speckles" on screen


Could be the screen burn from watching T.V. on a show and the thing burnt in (in this case the colors, yes it can burn colors.) and there's nothing you can do. The insides of the T.V.'s have plasma gases which can flow out of control.

Pulsing/strobing on black screens or dark backgrounds


It is very likely that there are electrolytic capacitors going high in ESR on the processor and driver boards, and also in the power supply areas. The tech should be able to see this by monitoring supply distributions with a scope.

Depending on the complexity of changing the caps on the boards (if it is actualy a cap problem), the best choice may be board replacements.

In almost all the cases where I had this type of fault, it was a number of capacitors that had to be replaced.
