from
PartStore.com
it was mounted to the case that holds the lamp. had to remove the back panel, etc. Also think I had to splice in the fuse or something. was a while ago.

i purchased a NTE8115 from my electronics supplier, closest I could find.
Radio shack also has them.

remove the back cover and measure for continuity across the thermal fuse
above the lamp housing.
if open jump it wth a 5 amp fuse, be sure to close the safety switch with
the small blue lever then try to power on.
If comes on ok you will need to replace the entire ballast assembly to get
that fuse.
Panasonic does not have a part number for just the fuse on the PT40LC
series.
It is possible to cut off the fuse and replace with another but dont solder

Just replace Blub.

most likely the bulb has blown, often they will actually shatter which can sound like a large popping sound

you may want to try to do a hard reset, the way you do that is, you turn your tv on, and unplug it while it is on, after 15 seconds, plug back in, should turn itself back on, if not turn it on, and see if it is gone, if it isnt gone, you will have to look online for the code to get into the service menue, there will be another reset in there, that should definatly get rid of it.

I had the same problem.  The TV is in store mode.  Unplug it for a few minutes, then plug it back in and select Home mode.

If the la,p still works, just reset the timer and wait for the lamp to go bad, Which it will do eventually, but lets not fix it if it ain't broke. In the mean time you can find that lamp online anywhere and by the time you have to buy one it may be a little cheaper. If this helps please take a few minutes to rate the response. Thanks

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".

Pull the left front panel off of the unit and you will find the lamp door behind that panel. It is very simple to pull the lamp and most times you can even see the element in the lamp has blown. You can easily buy and install the lamp yourself.

better to call the manufacturer so they can test it and check for problems. If still within warranty they will replace it, I guess.
