I just had my picture go out two weeks ago. I took it to a local tv repair shop. They replaced the thermal fuse. I also had a spare lamp so they also replaced that. I'm not sure if they reset the lamp meter but this is what I found surfing around...try at your own risk. I'm going to try this when I go home tonight.

Good Luck...

Press the power button to turn the unit on.
While pressing the Vol-(volume down) button on the projection display,
hold down the PIP button on the remote control at the same time for more
than 5 seconds. When the reset procedure is complete the following message
will appear on the screen. "Lamp time was reset to 0".

Many projectors use a lamp hour timer for predicting bulb life so they can give you fair warning of impending failure. Since a bulb may be removed and reinstalled because it is still working or another used lamp installed, the timer is not automatically reset to zero when the lamp is replaced. I surmise your set is complaining because the timer was not reset or the time verified when you changed the bulb.

To fix the problem, buy or borrow a remote control; a universal remote control with a menu button may work. (If you borrow a universal remote from a friend, be sure to record the code for your friend's TV first so you can set it back before returning it.)

You could probably get back into the timer reset menu by removing the new lamp and reinstalling it. Caution: follow the directions on page 68 of the user's manual or the sheet that came with the bulb - let the set cool for an hour first, unplug, and wear gloves when handling the bulb since skin oil can cause discoloration and possibly an explosion when the bulb gets hot. You can download the user's manual from Panasonic's support page for this set.

If you can edit the timer hours instead of just resetting, you may want to set it for the number of hours the new bulb has been used.

It is likely that you can get into the lamp timer menu if the set is in service mode, but the user's manual doesn't tell how to get there (I don't have that info either - it's in the service manual, which may be available online from a third party for a price). Usually it is something like holding a volume or channel button on the front of the TV while turning it on with the remote control. After that you need the code to switch to the timer menu. If you have problems getting into the timer menu, ask your dealer's service department or try calling the Panasonic help line listed on the bottom of page 68: 1-888-VIEW PTV(843-9788).
