Question about Samsung HLS4266 TV

The picture has white dots on the display. It started with a few and has gotten worse. I believe it is a problem with an IC on the digital board.

Hello:

The white dots are mirrors that have gone bad on the DMD Chip (Digital Mirror Device). Its the chip that has about 65,000 mirrors on hindges that tile back and forth depending on the what polarity of voltage is being applied to it. This chip is part of the DMD Module, I do believe you can replace the DMD chip without replacing the DMD Board assembly. But your problem is the DMD chip some of the mirror on it are sticking that is why you see the white dots...

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

It's a connection inside the TV that's faulty. It could be as simple as reseating the ribbon cables that connect the control board to the glass display. Or it could be that the fault is on the board and needs to be replaced. The fact that the problem comes and goes should tell you it's fixable.

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.

Samsung DLP HL-S4266W White dot problem


Its the DLP IC chip itself that is bad. The DMD board is where the chip resides but if you order a board, it will come without the chip. Its not cheap and the replacement is tricky because the DMD board must be removed and then an alignment of picture centering will be necessary.
