    Davis Powerbeam VI (my new toy) AKA Kodak DP800 (or DP880)

    Symptoms:
    It powers up (for like 2 seconds), and then turns right off.

    I will butcher it soon, and take the multimeter to it, but other than that, I am stumped. I honestly would rather have a "pro" take a look at it, providing i can find a place that is rather cheap.

    So, providing this isnt a simple fix, do you have any suggestions as to cheap electronics places?


    Here are some of my ideas with what the problem might be.
    faulty temp sensor
    blocked filter
    bad fuse
    faulty power supply

    please... toss out some suggestions.. I have this problem posted at like 8 different forums, and nobody can provide any help.

    I will be tearing it apart, I think. I really cant afford to pay very much to have it fixed, as I am a poor college student.

    If you guys can provide some ideas as to what I should look for, it would help.

    Does the lamp light?

    I'm wondering if it's past it's rated lamp hourage, and is shutting down due to that. There should be a way round this I would think, if that's the case.

    Another guess is maybe it has a heat sensor that will shut the pj down if it over-heats. If the sensor is faulty i.e open circuit, it may be reading a few hundred degrees and shutting down. Test it first of course - it's resistance should change with temp. So put a meter across it and see what it reads, then hold it in your fingers an see if it changes. Replace it with something like a 5k resister may get it running.

    Try CAV in Wandsworth for info maybe - they're the official repair people for Davis stuff now, and they might be able to point you in the right direction.

    Gary.
