We have had this TV for almost 2 yrs. Lately, if it's left on for awhile,
it shuts off automatically. We can't see anything in the manual about a
"timer" which maybe we have set (although I'm sure we haven't). Does it
heat up after prolonged use? It's very annoying since it always seems to
happen just when something crucial is about to happen in our programme, and
although the sound still works, you have to wait until it completely powers
down before you can turn it back on again. Does anyone else have this
problem, or know what might be causing it? Thx
