i was just watching tv when it turned itself off ! the on / off button shows a red light which normally goes green when it is switched back on, but it just stays red. I have tried switching off at the wall but it is still the same. any ideas ?
Sounds like your tv is in stanby mode. Try new batteries in the remote. Or try pressing a channel button on the tv itself to switch the tv back on to rule out the remote as a cause.
