    I've been having a problem with my 14y/o Mitsubishi
    VS-585R 50" rear projector TV - It's performed pretty
    flawlessly through the years; so far all I've had to
    replace on it was the sweep board.

    Lately,though, and with increasing frequency, it spontaneously turns itself off, sometimes after
    having been on for quite a few hours, sometimes
    several times right after I turn it on in the a.m.
    There is usually a brief, sharp spike in the
    sound VOLUME just as it shuts off.

    I had the local Mitsubishi authorized repair
    people come and look at it but they said they
    had no idea what the problem was, which was not
    very encouraging. Basically told me I should
    buy a new TV, which is not an option for me at
    this point. That seemed like kind of a cop-out,
    and I just can't believe nobody's ever encountered
    this problem before.

    Any ideas on pinpointing the problem?!! Any help
    would be greatly appreciated!

    Received a response on this problem from another Forum and the poster suggested I try replacing C906 on the main defector board - a 22uf 100 volt capacitor that he claimed
    can cause a number of voltage problems on the chassis....

    I also tried calling the local Mitsubishi service center again and they said it could be a number of things, including even vertical sweep problems triggering a safety
    shutdown... the peculiar thing about the shutdown each time it happens is that there is a split-second spike in sound
    volume just as it happens.

    Anybody have any ideas on this or where I could get a
    replacement board for a set this old (1989-1990), please
    speak up! Thanks...
