I believe it is the digital projection chip that is beginning to fail. Causing white and black spots to appear. To repair this may cost more than a new tv. If you want to attempt it yourself check out the above link. Hope this helps

My tv has small white dots of lights in most of the screen can this be fixed.


Ensure your input device is not causing this, by changing the TV input to a different video device. Then, look for any loose contacts on the RC cable or input cable. If nothing works, better refer it to a qualified service technician.

Bright white spots on mitsubishi wd-73833 I just replaced the lamp and now these bright white spots have started to appear!


This unit uses a DLP (digital light processor) chip and if this starts to fail then you will get spots appearing on the screen. The DLP chip will need to be replaced.

GREY SPOTS ON BACK OF SCREEN NOTICEABLE WITH WHITE


Hi if your tv is a dlp it might be an issue with the DMD board Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!

White spots on TV Screen


<span id="ctl00_ctl00_MainColumn_CenterColumn_ThreadSolutions1_Repeater1_ctl00_lblSolution">DLP/mirror chip is going bad. A common problem on Sammy TVs after 2-3 years. Chip is user replaceable (try samsungparts.com or ebay) for about $150-200. Sammy was (last year) repairing the DLP White Spot problem for free. You MUST talk to ECR (executive customer service) to even think about getting that consideration--forget the standard CS people. Don't know if they are still covering this out of warranty in 2010.</span>

Numerous white spots on Smasung DLP TV


If your Mitsubishi TV has white spots in the picture , you can call Mitsubishi @ 1-800-332-2119 and request a free DLP Chip to fix the problem. They will send the New DLP Chip at no charge to a TV Tech in your area to install it for $200 flat rate. That is about a $250 savings if you had to pay for the chip . Call them with your TV's Model number and serial number and let them know when and where you bought the TV.
It saved me some hard earned money and now my TV is like New !

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.
