White spots appearing - Mitsubishi WD-73735 Television

You may have bad pixels. What type of TV is it?

I’m happy to assist further over the phone at https://www.6ya.com/expert/jason_ee8f979baffc115f

1,white spots appeared on screen,means the DMD is broken,you need a new DMD.
2,the projector running off after only a few minutes,means the Inductor (Sensing element),near the Color Wheel. Use a cotton swab moistened with alcohol to wipe the Inductor.

Have a good day!

what is the cause for the televisions screen to get white spots that spread

The projection engine have problems,it the cause.Two years tv shouldn't have this problems already.Call talk to mitsubishi,might get some help the cost of the repair.

take the spinny thing out and ask bob the man to replace the rubby thing and then take the ducks guy in and that should do the trick.

It's a bad pixel spot. I have a TV that has a dark spot.
Nothing you can do about it.

plssss use for oil

above information is a bit extreme - most likely culprit is dirt/dust on reflecting mirror.....

If the white spots are appearing in different spots or "Moving" it is the DMD board beginning to fail. Samsung DLPs seem to have a lot of DMD board failures. I would expect it to completely fail in the next couple months.

If there are only a couple small white spots that never go away it could be a mirror that is seized on the chip, but it's far more likely that the DMD board is going bad.

the pixels are sticking . slow degeneration of the display panel
