Most likely cause is the optical light engine this set uses--starts sometimes with a few then more and more.....

SOURCE: I have White and black

I developed white spots on the screen of my Mitsubishi WD-57734 in increasing numbers over days and weeks. I called a repair service who quoted me $1500 to replace the light engine. He suggested I call Mitsubishi Customer relations at 800-332-2119 option 5 which i did. To make a long story short after several conversations with them they agreed to replace the part for free if I picked up the labor (Would have been less conversations if I had the original purchase receipt). Instead of $1500 I paid $250. The tv was only 3.5 years old. Perseverance paid off.

Little white dots in tv modle# wdt657 what are they how can i get them off


Your TV is DLP projection TV. DLP is Digital Light Processing. Digitally processed light coming out of DMD (Digital Micro mirror Device) is projected on the TV screen. This DMD is made of thousands of tiny mirrors & the size is about 0.7 inch. These mirrors are fixed with tiny hinges for its movement. They reflect light as per processed signal. DLP is invented by Texas Instruments. When there are dots on the screen, that means the tiny mirrors representing the dots are stuck in its position. If the dots are few & the viewing is bearable, just leave as it is. If the dots are more than bearable then you will have replace the DMD chip which is quite costly.

I have white dots starting to appear on screen. what's the problem? other than paying over 1800.00 and already having problems.


It sounds like the problem is coming from your DMD board this part has millions of micro mirrors that have to turn from the on position to the off position thousands to times per second to reflect the light some of this mirrors are getting stuck and that is the reason you get this effect here is some info about your TV projection

I have a Mitsubishi WD Y-657 that started out with a single white dot. Now there are over 50. This all happend in a week. I believe they are dead pixels. ?? What to do?


Dead pixels are a problem with LCD screens. You have a DLP set, so this is not possible. I unfortunately don't know anything else about this problem.
