Can't reset Panasonic lamp hourmeter

    I have a Panasonic PT-45LC12 LCD rear projector TV. I just replaced the
    bulb and tried to follow the instructions to reset the lamp hour meter;
    i.e., hold down the TV's Volume-- button while pressing the remote's
    PIP/Play button. It didn't work...even after several attempts, and
    after unplugging the TV from the wall socket and reconnecting. Any
    suggestions would be appreciated for solving the problem, or am I just
    stuck with a TV that doesn't obey commands anymore?

    Diligence, even the professional technicians have occasional difficulty
    pursuing this specific function on the
    Panasonic sets. Try again, advance the volume to about 1/3 the way then
    attempt he procedure again. Eventually it will work unless the EPROM data is
    contaminated, which is highly doubtful.

    Thanks, Art, for the tip...but I guess it takes a better man than I to
    make that process work. Tried it for 20 minutes last night, with every
    conceivable volume setting, and still no results. Guess the EPROM is
    bad.

    Have you tried it with the set turned OFF? I struggled with a Hughes
    projector once which required a switch sequence like that, but it only
    worked that way.

    This works. Here is what I did.
    How To Reset Panasonic LCD Lamp Timer:

    Step 1: I turned the volume all the way up.
    Step 2: Hold the Volume - button on the TV (Not the remote) until it
    was at 0. Keep holding the Volume - button down.
    Step 3: Press and hold the PIP/Play button on the remote until the
    message shows the timer has been reset to 0.

    Hole that helps.

    Thanks to everyone who took the time to send me a suggestion. I finally
    got the hour meter reset--and the key was so simple I'm still shaking
    my head. I'd been trying to reset the meter while the "Reset lamp
    timer" message box was showing on TV startup. Based on the information
    I've received on this forum, I figured it was worth a try to reset the
    meter AFTER canceling out the message box. Sure enough, worked like a
    charm. Duhhh...

    Some of these units the lamp reset has to be done with the unit in
    "Standby".
