    I have an InFocus projection unit with a bad power suppky. I have fa
    action, and logic board action, ( 5v, 12v, 8.5v, -8.5v, but no 28
    I assume that the 28 - 60VDC is the bulb voltage since I have no lam
    lighting. Is there a particular component that I should be checking
    Anyone have schematics for the following?

    NMB power supply SP1621
    IFS p/n 520-0069-04

    Thanks for your help in advance.
    I have access to soldering tools and multimeters.

    Schematics, not available.
    Parts, not available.

    Call Infocus and if it is still a supported unit you can ship it to
    them for flat rate repair of around $250.

    If it is obsoleted by Infocus, time to start shopping.

    A very well experienced and trained technician might be able to repair
    it if the part failure is a standard part without any schematic.

    Infocus is factory exchange/repair only. At one time they had a few
    authorized independent repair shops in the US and you might be able to
    send it off to them.
