Re: oscillate dark to light and back again

If you get the problem initially when you switch on the tv means improper misalignment of screen control or screen control malfunction. Problem continuous means check filament supply when the screen in dim condition. There is no supply around 3v change filament supply resister and check any dry contacts.

Hello, why does my plasma tv have thousands of red and green flashing dots all over the dark parts of screen after it has been on for roughly half an hour? if i turn tv off for a while then turn back on...

I had a similar problem but mine was just red specks that showed up in dark scenes. I opened up my plasma and found the adjustment pots that are labeled Vsc, Vy. I then marked the factory default with a sharpie first. Then I lowered the Vy a little and my red specks disappeared. Now my tv looks awsome again like it was new.

I had a similar problem, except I could make the screen and sound come back by banging on the the TV. I opened the TV and poked around on the circuit card and found a loose pin on one of the regulators, labeled C3852. I resoldered the pins and its working fine now.

Power problem?

Try th set in another room, if only to see if this phenomenom happens with other light fixtures or appliances. Would suspect the switching type supply in the TV as suspect if the problem "moves" with the set....accordianman
