    Hi, I just got this TV from a friend and I have never had one like this before so I was wondering is there any special way to clean the screen? Can I use Windex or just water?

Found that the thermistor/temp measuring device is suspect, no resistance across legs. There is a label there that says F701 see service manual
http://www.goodmans.net/get_item_th-tf117c_thermal-fuse-117-degrees-celsius.htm
I went here for a tech manual for the Panasonic
tv.
http://www.ManualsParadise.com
then ordered
Manufacturer: Panasonic
Part Description: FUSE
Part Number: LSJA0411-1
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

Power button blinks green about 1 minute then goes red


There is an additional problem,

if the bulb had been replaced by a technician, call them back and ask for additional support, since they did not fix the problem.

Turned itself off. I turned it back on and the green power light blinks for awhile then blinks red for awhile.no picture or sound


Get rid of this TV. Had one and replaced the bulb and light engine many times. Just buy a Samsung or Vizio 50+ inch instead and be very happy. Those Panasonic projection TV's were terrible. You will find a 50 inch Vizio for around $500 bucks and it will blow your mind how great the picture looks.

It very well could be the ballast. I unfortunately have this tv and keep extra bulbs because they go out about once a year. Last time when I replaced the bulb the tv blinked and the red lamp light flashed like it does when the bulb is bad. Ballast repair kit fixed it up. This is certainly a design issue but you'll get no help from Panasonic. If tv comes on the goes out after a while, clean the fan filter.
