Is it RPTV, old set? If so, probably need to just replace the set. Replacement of the projection tubes is very, very expensive; more than the set cost new.

There is a good post on this subject at the FixYourDLP's blog... I believe your issue is result of a defect DMD DLP Chip. You can read more about this issue here:

White death DLP TV


White dots on your RPTV television are the result of the DLP chip being worn out. You can replace it very easily by buying a new DLP chip for just under $190 and installing the new chip. There is a very good forum over at fixyourDLP that offers tutorials for replacing the DLP.

Had one last week and now there are 6. they are


Hi,

You get white spots inside the samsung DLP tv due to bad Digital Micromiror Device , or bad DMD board .

What is actually the problem is the DMV chip connected to this board . Inside this chip are 3 million tiny mirrors ,and when they physically get stuck , they either show black or white instead of a color
This is well know problem with SAMSUNG DLP...

The DMD chip is failing.If not under warranty expect to pay a few hundred to several hundred to get it fixed

The mirrors on the DLP chip are slowly sticking either fully open (white) or fully closed (black). The part that contains the DLP chip is the Light Engine. It is the most expensive part of the TV.Only the Samsung TVs has this issue.

Replacing the DLP chip and the micro mirror would solve this issue...

Pleaserate this solution,

Red band at top of tv


Hi,if its a an LCD RPTV it sounds like a light engine problem.Basically your tv uses 3 LCD chips that create the image .Each chip is like a tiny screen that blend together to get the colors and picture right.They are green,red and blue.When they start to fail you will start to get color discoloration or that red band you are getting.May the Lord Jesus bless you!

Cannot adjust convergence on Mitsubishi RPTV


as long as there is no bowing in the picture and the color does not want to move then there is probably just a bad resistor on the convergence IC that controls the color alignment , thus the resistors would have to be tested to find the low valued resistor on the IC
