TV won't shut off

The TV picture loses its color(almost looks lke a partial black & white negative)freezes up and the TV won't shut off. I have to pull the plug to turn off the TV. Upon restart, evrything is fine for about an hour when the TV again gose into the same mode as previously described. Pulling the plug and restarting the TV restores the picture for a short period of time. The lamp is on.

    Have the same problem. Picture freezes in black & white like
    a negative with lots of snow. Even the closed caption is
    frozen. You cannot change channels, you can't do anything except
    turn it off. Repairmen came out & said they couldn't find
    anything wrong & maybe it's my cable box. Problem is getting
    worse. The only thing the repairman said that was helpful was
    that when you turn it off, you have to leave it off for 2-5 minutes
    until the fan shuts off. Otherwise, it just keeps recycling
    trying to come on, but it can't. I have a service contract on
    this unit, but apparently they don't know how to fix it?

Color problems vizio lcd hdtv


If your tv has a custom settings area, first turn all color down on set so picture looks black and white. Now in color settings look for red blue and green color bars. Use the bars until the picture looks as true to black and white as possible. Also, try changing color temp.

That sounds like one of 2 things:
  1. Color wheel
  2. Light engine
Color wheel because of the losing color, but the light engine because of the picture freeze. It's very difficult to judge since I can't be there to see it. I'm leaning toward the light engine though. The only fix is to replace the DMD board, or entire light engine.

Black and white screen...


The color wheel can cause a black and white picture but not the jumpy or negative look.
Those symptoms are usually caused by the DMD assy which drives the color wheel and is somewhat expensive, most of the time you can purchase the whole Light Engine which includes the DMD assy for the same price.

HLN4365W Picture goes askew and turns to black and white.


Hi...what you are seeing is the DMD board (digital Mirror display board) going bad. And if you leave it turned on like that it will damage the DMD mirror and freeze that picture into the mirror. It will look as if someone etched it into the mirror. DMD boards can be repaired and some cannot be repaired. The DMD board can be replaced. The DMD mirror can also be replaced too.

Picture freezes Black/White


It's most likely the digital board, Samsung p/n# Bp94-00385a but I'd trace test both the digital and analog first before blindly replacing it - too costly to just guess..
