I am getting little white dots starting to show up on my tv screen. It started with 3 and one by one i am getting more and more...i'm up to 13 now. it is an 50" Samsung DLP rear projection TV. Just wanted to know what the problem and if it can be fixed.

DLP chip needs replaced...about $200 for the chip and replace yourself. YouTube has videos on how to replace

projection tvs can display white dots from the dust that is on the reflector mirror your lamp shines the picture on before it is reflected onto the front screen of your tv, one must be very careful when cleaning this, may be worth a service man doing it for you

It is the Optical lamp board

The random whit dots you are seeing is more than not the DMD or million little mirrors board. The white spots represent some of the mirrors that are sticking in the on position. In that case they are always reflecting white light from the lamp. I don't concider the DMD board a do it yourself repair since on the older DLP set it requires mechanical alignment as well. The best thing to do is contact a techincian and see what they might charge to repair the TV for you. Please take a few moments to rate my answer...Thanks..

The only thing you can try is to adjust the tiny control on the Y board, if you want to try do this. Open the set , set it up so you can watch it with the back off. now looking at the back on the left side you will see a circuit board larger connected to a smalled one or two that go to the screen edge . on the larger board look for a few small controls, mark their positions with a dark sharpy then turn each a little while looking at the dots to see if one makes them better or worse. If one control effects the dots try to center it for the least amount of dots, if no effect is observed when a control is turned return it the original position that you mark before starting. if the dots do not clear either the Y board is bad or the whole scfreen is defective.

this seems to be an issue either with your DMD board or with your Digital Video board... turn on the tv and go to the menu if the white dots appear on the menu the issue is with your DMD board but if they don't show on the menu, the issue would most probbaly be with your Digital Video board

Its hard to say this but your tv has a bad PDP Panel unfortunately the panel is not available for the tv. If not in warranty see if your home owners insurance will cover it.
