I have a panasonic 'quintrix' 32" widescreen TV. It's quite old and very bulky and heavy. When I have it on ITV (through a virgin media cable connection) and the national news and weather has finished and the regional news 'Scotland Today' comes on, it switches off and goes into standby. I can switch it back on, but if Scotland Today is still on, it switches off again. If I change channel it will be fine. Also, it never switches off when I watch any other programme whatsoever. Anybody know why??
