Last night I exited the pvr list and the tv turned off. Every time I tried to turn it back on it just went off again. We just bought this tv so I thought it might be defective. When I turned the pvr off the tv came on, of course with no channel feed. Had to reboot which fixed the problem. Why would this happen, so frustrated that the problems keep up, at least every couple of months there is another problem, when will it end????
