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...

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.

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?
