Sounds like DLP chip not making good contact or bad. It's not soldered, but spring clamped down to contacts.

Repair dead pixels?


Dead pixels can not be repaired.
The model# WD-52525 you provided is for a DLP TV.
If you are seeing white dots on the screen it is due to a bad DMD chip or light engine. Unfortunately, it is not a cheap fix.

Good luck

Those are called pixels depending on the manufacturer of the tv they may replace depending on age size and location of the dead pixels

White dots on the right side of the screen


these are called dead pixels if your television is under warranty you should replace it with new one cause dead pixels generated new ones until it will fill up your screen completely.

I have blue dots on the screen. I cleaned the glass on the projection bulb and the prizm but still have blue dots.


Your tv is an LCD projection one - in which the image is generated by 3 small LCD screens. The blue dots are pixels from the blue LCD that are dead - always fully open.The only fix is to replace the LCD panel and that is going to cost you around $300.

White pixels are STUCK pixels, not dead. Read the warranty beacuse at a certain number of stuck/dead pixels, the tv is repaired for free by the seller if is in warranty period.

I have a 42" samsung rear projection tv which has developed 1 white dot about 1/16" it has been there for about 3-4 days. Is this a sign of more trouble to come? Can it be fixed, or is this a warranty...


It is a dead pixel and samsung will not honor any warranty on dead pixels under 20 of them. It is considered within tolerence level despite it being a damn pain and a fault that shjould be rectified by replacement.

But you can try.

Good luck!

Yellow Spot dead center on screen


most likely the yellow dot is due to a burn in the picture on the "green" lens. It's not removable because it's burned it, but you can try cleaning it because sometimes, dots are caused by dirt. The worst that can occur is that if the dot is permanant.
