Question about Panasonic PT-40LC12 40" Rear Projection HDTV
How do I know that the bulb is bad by looking at it. Last time it blew
it actually made a loud popping sound and it was under warranty and
by replacing the bulb fixed the issue.
No popping sound this time and the wire on the bulb looks unbroken.
Is that all I look for in the bulb?
What small blue lever?

Check that the thermistor/temp measuring device is suspect, no resistance across legs. There is a label there that says F701 see service manual
I went here for a tech manual for the Panasonic tv.
Part Description: FUSE
Part Number: LSJA0411-1
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
Panasonic does not have a part number for just the fuse on the PT40LC
It is possible to cut off the fuse and replace with another but dont solder
