Tv has white dots all over it. It was where you could turn it off and turn it back on and it would be a little clearer. Now it is the same all the time.

Have you tried playing with a DVD? If it does the same, the main board needs replacing.

Cracked screen & white dots appearing since the crack appeared


I have a Mitsubishi TV and had the same problem. There is a mirror that moves to control each pixel. When some of them fail to move you get the white dots. Google your problem and a company will come up(sorry forgot the name).,you can buy the new part from them and they have exact utube videos to help you do the repair. Took me about an hour. Part was around $150. Very rewarding feeling when you turn the tv back on with no white dots.Still dot free after two years

My mitsubishi 65in tv has a lot of small white dots on the screen what causes this?


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

White dot for DLP Projector TV is not because of the light buy. It is caused by aging DLP chip ( DMD Chip.) Your TV DLP Part should be the following image:

White dots in plasma tv


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.

I have white dots on the screen of my hsl4266wx/xaa?


If these dots are only seen when the picture is on I would look for the Optical Block to be causing it. Are the dots in the same place each time you turn it on?
