Here's the problem. While watching the TV, the video will just disappear. Sound is still on and sounds normal. Lamp is still on also. Switch from one input source back around to where you were and picture is back. May not disappear again all day. Doesn't do it at any certain amount of time being on.
I did replace the bulb with a compatible one about two months ago instead of an OEM one. Just ordered an OEM one to put in it though just in case it is bulb related somehow.
Has had the board replaced years ago, along with a new color wheel and DMD chip a couple of years later when dots appeared.
