I have a Samsung HLN567W TV. Recently I started having problems with it. When its turned on, the colors will look bad, just like when you have your computer video settings turned down to 256 colors. It will stay like this for around 5 min, then the Picture will start getting very blurry and finally the TV will shut off. At the point it starts going blurry, The remote will stop working, I will see the light flashing on the TV but It doesn't do anything. I will then need to unplug the TV and plug it back in before it will do anything again. I tried to change the lamp, but that made no difference. I checked and cleaned all of the fans. Anyone have any ideas?
