Philips/Magnavox TV Schematics

  1. I have an inoperative Philips/Magnavox TV set and no schematics. Where
    can one go to find/download/purchase schematics and maintenance
    documentation?

    I think it took a hit a few months back when we had a power outage. One
    of the components let all of its smake out, but upon opening the set up,
    its not evident which one. Nothing works (not even the pilot LED).

    Its a chassis no. 25B800-7562

    Paul:
    The schematics may be of little help unless you first can do some basic
    troubleshooting and testing without them. There are NO step by step
    troubleshooting procedures and the schematics are only most useful to those
    who are experienced in television repair. A dead set due to a power surge
    is usually one of the simpler repair scenarios.
    Obvious first steps after your visual inspection would be dust off your DMM
    and to test the power supply components and look for properly regulated B+,
    in addition you should test the HOT to see if it is shorted and test for
    other faulty components in that area of the cicuitry.
    You may want to go to the website for this newsgroup at
    www.repairfaq.org
    there, with some of your search time, you will find a weath of repair,
    troubleshooting, testing and safety information.

  3. I've done quite a bit of electronics repair (and a little bit of TV
    repair), and I wouldn't start poking around in something unless I had
    some idea of what sort of circuit I was looking at.

    I'd much rather rely on a schematic than trying to trace the power
    supply around the traces of the main board.

    You do not need a schematic or service manual to check and test the
    components that Sofie indicated in his reply post. As he said, "dust
    off your DMM ........."

  6. Try answering the question originally posted. That is, "where can one
    obtain a schematic", not "do I need one".

    I'd much rather have one in hand while searching for faults. I don't
    repair TV sets as a profession.

    THANKS! I may check that out myself. I've got a few things here I could sure
    use a schematic for to finish up.
