My 73" screen started going dark. We figured the lamp was going out. It didn't go out quickly like when the lamp went out in our 65".
We watched it until it got too dark to watch, while we waited on the new lamp to come in. When the lamp came in, we installed it, and the picture now is completely black. The green status light flashes, then goes solid red.
We never got a picture at all, after replacing the new lamp.
