    This Sanyo DP26648 television powers up with a white screen. Looking through
    the archives, it has been reported that there is a defective ribbon cable
    that causes this problem. One specific report which is detailed here:
    http://www.docendi.org/sanyo-t240744.html?s=374b1e6b350125947468fde1448e0935&
    says,

    "Clean glue like material from spaced further apart trace of FFC ribbon - or

    Replace the ribbon wire < P/N: N6CD FFC>

    Connects panel to timing control assy."

    The comment about the glue like material makes sense. The second part about
    the "further apart trace," doesn't make sense to me.

    Secondly, the connector that is interfaced with the cable seems to be one of
    those zif connectors. Anyone know the sweet spot on how to open those
    things? I know that one push in the wrong direction will snap that thing
    right off the pc board. If need be, I can photograph it and upload it later.

    Thanks for your reply.

    I wound up prying underneath the black piece very gently with two small
    screwdrivers. I just made my way across the piece with the screwdrivers
    putting slight pressure on it. It took several times to see any progress.
    Eventually, the piece started to rotate and finally stood up at a right
    angle. I got the feeling that one extra ounce of force was going to destroy
    that thing.

    I really didn't see anything that resembled glue in or near the connector.
    There was some double-sided tape midway down the cable to secure it but I
    don't see how that could have interfered with the connections.

    Thanks for your reply.

    I received the new cable today and installed it. Problem fixed. I guess that
    was a good tip after all.
