    Greetings Gadget Gurus...

    I've searched the archives but found nothing on the
    subject...

    I have a 1989 Mitsu projection tv model VS-5002R (51")
    that won't come on. It makes a clicking sound like it's
    trying, and will flash lines of color after several
    attempts, but something won't quite catch. The problem
    was intermittent but it now seems thoroughly cooked.

    A friend thought it may be magnet related but that's as
    much as anyone's been able to offer so far.

    Any clues/hints/thoughts/speculations/conjectures are
    appreciated.

    PS: please reply here - thanks!
     
  2. Get your ESR meter out and start checking all the electrolytic caps in the
    set. Check out the vertical deflection and power supply circuits.

    This model suffers from vertical failure associated with a defective cap in
    the power supply.
    A known failure mode and a kit is available from Mits to overcome this
    problem.
    There is also another problem associated with the horizontal driver
    transformer.
    You would be best advised to unplug the set and have it serviced before the
    CRT's are ruined from repeated attempts to turn it on.
    There will also be quite a number of leaky caps in different areas of the
    circuits that will need replacing to circumvent future failures.

    Good Luck,
    Bill Jr
