There are a number of different problems that you could be experiencing, including a potentially defective digital micomirror device (DMD). Unfortunately, the only way to determine if a part is actually failing would be to contact a factory-authorized service center.


Problem is a chip that will need to be replaced. Possibly D or Y board.

    PS. There have been reports of the HDMI cable being old or bad
    connection that may cause this. Generally though, its a bad chip.

For this kind of problem, you need to check the video connector. Check if there's a bent pin. Bent pin causes tinted shade on the display.

If there's no bent pin found, you need to contact the manufacturer of your screen and get the latest upgrade.

Have a great day!

No need, the screen is indeed dying and there is nothing that even the can do to save it.
You must replace it, and quickly, otherwise when it will finally fail completely it may fry the video chip.
