  1. Hi!
    I have a Sanyo HD TV Mdl DP32746 that has good sound no picture and
    no light on the screen, should I guess the back light inverter or the T Con
    Thank you for any help you can give me.

    It's most likely the inverter, but there is a quick and easy test to
    help decide. Working in a darkened room, turn the TV on. Does the
    screen get lighter, even momentarily? With the back of the TV off, do
    you see any lighted areas on the back of the lcd panel?

    Googling the model number indicates the TV has a history of inverter
    failures. Checking eBay finds that there are LOTS of tcons available,
    only one inverter.

    A brief flash on the screen indicates an inverter or CCFL problem; if
    the backlights never come on it's most likely an inverter problem,
    often a fuse.

  3. Not so, not in the U.S. anyway. I bought service literature for Sanyo TV,
    stereo, and VCR products all the time back then.

    Trick was, if you were not a dealer, you had to order the manuals and parts
    from a distributor, such as Fox International.

    Documentation is seldom a problem. Anyone with a little intelligence
    can locate schematics on the internet. My favorite source is Scribd often has documentation, even training
    manuals for some models.

    In the case of backlight / inverter failures, the service manual is
    seldom useful. In most cases the tcon and the inverter are considered
    part of the panel and are not documented. Again, all it takes is a
    little creativity to troubleshoot these.
