Screen flashing This tv recently started this problem after about 5 months. After it is on for about an hour on bright images like sky there is intermitent pinkish shimmering on the screen. These flashes continue then until the set is shut down. Thanks

    tv screen looks like a strobe lite

    Exact same problem. The picture is perfect for the first 10-15 minutes after being off for 12 or more hours. Once the flashing starts, it won't stop until the tv is off for another 10-12 hours. So, I get 10-15 minutes of quality viewing a day. GREAT BUY!

You need the voltage on the ps board and the ysustain board adjusted. Possibly the z sustain board needs replaced if this doesn't fix.

Flashing screen on Toshiba 42HP66

Plasma sets use high voltage to produce their displays and it sounds very much like the HV supply is losing (or has lost) regulation likely due to the impending failure of a semiconductor.Check to see if Toshiba has any extended warranty on this since it could be a series problem.If there is none, ask for a price on a new or repaired supply on an exchange basis.

900 hours and I am seeing some image retention. How to remove them?

In a few words, you can't.
Panasonic Plasma Screens have a movement option that slowly moves the screen around a few milimetres
I the burning is bad and all you can see is Sky TV's frames or Sport frames, the way to reduce the effect, and this is official, is to turn up the screen brightness on a white background. This will burn the rest of the screen to a similar level!
Unbelievable but having done that for a number of hours, when one increases the brightness to compensate for a burnt screen, it is slightly better.
(I do not advocate that, I would not let it burn in the first place.)

Good luck
Hope that helps.

Black/Green Distortion - Picture Quality - Wharfedale

This is no solution but a point in a probable direction.

A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.
