Question about Panasonic PT-40LC12 40" Rear Projection HDTV
I just had the ballast replaced on my PT-40LC12 40 inch Panasonic. I have only used the TV for a total of 5 hours, and now the lamp button blinks with no picture after I turn it on. I get a picture for 30 seconds, then blinking lamp button. Can you help me?
Sent me the serial number, and I can check for any re-call ...

Found 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
