Ours does that every now and then. We think the wire at the back comes loose or something because once it would not come back on until dh played around with the wire. Most of the time it comes back on after a few minutes.
differentID, now that sounds complicated Where is DH when I need him? . I have just figured out that our sky remote turns the tele off though. See, a learing experience <goes to locate cable amongst sea of cables behind tv> I may be some time !
DifferentID, thank you for fixing my tele. turned it off, then on again. And now I have that stupid annoying man telling me if I turn onto stand-by I could power birmingham for a whole year...why do I give a toss about birmingham, what about my power?
