    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

    May want to have it service for intermittent shutdown. May be lamp or
    ballast related or just the fact that the fans inside are getting clogged up
    with dust and need to be serviced. Either way have it professionally
    diagnosed. At that time you may also ask the technician about Hitachi's
    pixel out specifications, which are in the training/service literature.

    Also you might try posting your question on:

    www.avsforum.com

    There is a section for rear projection sets that include lcd.

    Could be a bad connection somewhere inside. The wait is normal though, most
    of those metal halide lamps need to cool off before they'll restrike.
