    Samsung pn51d490a1dxza pixel problem

    Hello i have a 51 inch samsung pn51d490a1dxza and on the right side i am having some sort of problem with the pixels. I have not taken it apart yet but i will attack some pictures just to ask what is usually the cause for this? It is mostly noticeable when the tmobile commercial comes on with the pink screen or any other solid color comes on the screen. Pink is most noticeable and blue is least noticeable. Also when i first turn on the tv, alot of red pixels flashing across the whole screen.

      Panel Aging.

      Sometimes you can cover it up by increasing the Vs by 5 to 10V but the issue will return.

      Screen burn has retained the H logo.

            Ok one more question. I got it 3 years ago, is that considered old for a tv set like this? And to be doing this kind of thing with the pixels?

              Three years may not be considered old for a TV set, but if you're experiencing issues like pixelation, it's worth investigating further. Reach out to the manufacturer.
