This is a dlp projector and has a bad DMD chip. Most models are very similar. Here is a video of a similar repair.

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

I have a white dot on my lcd computer screen when the screen is black but with the screen on other colour the dot is not significant . I just wonder what the consequence of this dot is?


Hi.

Basically the white dot is a dead pixel, this is common with LCD screens. You have nothing much to worry about unless the screen develops more dead pixels which could lead to a screen replacement although its highly unlikely.



Regards.

White dots appearing on screen, also have black dots if you look closely...


It can be pixel problem. Every pixel has one transistor to switch off or on. I hate how manufacturers treat us because lot of them 'believe' that this is not a problem (must be more than 6-8 pixel problem on screen for changing). Sometimes little press with finger and shutting down screen can help, but it is possible to do worse if it is to hard press. Price for screens depend on that tolerating of bad pixels from manufacturing. Only few manufacturer can give you guarantee pixel free screen. It is good to know that we have right to return device after buying if we are not satisfy.

White dot on screen


Most likely its a dead or stuck pixel (a dot on the screen which makes up the overall picture).  You can read about it here (Link) .  If its a stuck pixel you may be able to fix it.  That wikipedia article gives some methods of removing it under 'Dead vs Stuck Pixel'.  However if its a dead pixel there isnt much you can do except bring it back to where you bought it if its still quite new or ring the manufacturer if you still have a warranty and try get it replaced.

Hi , 2 weeks ago i noticed some dead pixels showing up on my screen (white dots) since then i'm up to 10 dead pixels. What can i do? I heard it might be the dlp projector that has to be replaced...


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.

Losing pixels like crazy


Shure, you can have it fixed. I strongly suggest that you call around and check prices first. Samsung IS a quality brand. How many TENS OF THOUSANDS, if not more units do you think they make? Getting ONE bad, is a pretty god ratio. Sorry it had to be you that bought the bad one.

Theres a black dot on the top right side wat can i do to fix it.


Is this a LCD and is it a very small dot ? If the answer is yes to both then it is a dead pixel (a white dot would be a shorted pixel). Most LCD makers wont do anything about this unless a certain number of pixels are bad. The only way to fix this is to replace the whole panel and that will probably cost more then a new tv.

I have a Maxent MX-50x3 50 inch plasma. built may 2006, bought at best buy in april 2007. Allways has occasional red pixels randomly when switching inputs. Now we have vertical red lines and pixels and...


if you take the back cover off the tv, you will see in a white screw in almost every board, those are called pot. (potentiometer).
if you can get to meter the Ve. Vs. and Vset. start to screw or unscrew those white screw according to what the label says.
usually the ones who gives you the blue and red dots are the white screw on the right of the center panel, and the one on the right of the right panel right under the metal thing to hang on the wall.

Green and Blue spots on screen


Sounds like stuck pixels, you really can't fix that. Do some google research if you are curious what a stuck pixel is.
