    Sorry about the bold type, as I'm pasting this info. Sky.

    Has anyone seen this? And can you cover the DVI module to

    "prevent" this from happening?

    JVC AV48WP30 Important Servicing Note

    If You Remove The Rear Cover While The Power Is On You Will Destroy All Dvi
    Programming Inside The Dvi Digital Input Module. The Only Way To Restore The
    Programming Is To Send The Unit To Jvc. There Is A Light Sensor Inside The
    TV And When The Back Is Removed With The Power On The Data Is Erased From
    The EPROM. First Turn Off Set And Remove Power Cord Then Short Pins 1 And 2
    On The Sb Connector Of Digital Input Module. Module has to be sent to Japan
    by JVC, & the repairshop pays for it.

    This is true. Unplug JVC projectors always confirm that DVI box have
    the light sensor and jumper the pin block (it is six pin block and
    correct knowledge will be successful.

    Another way is unplug all the wires to the DVI box and service the TV
    as usual (testing probing etc). When done and unplug unit, plug the
    wires back on that DVI box and install panel back on. Done.

    By the way, I have service call for 2 day old JVC unit with dead DVI
    and I told Jack about it. I said bring component output dvd player to
    test. DVI just outputs component signals. And it is about 200
    dollars new or send out to reprogram as other had said.

    Cheers, Wizard
