Re: panasonic tv don,t turn on
ONE: Check the power strip to make sure it has not tripped out.
Mostly they have a reset button somewhere on the bar. You can test
the tv in another outlet around the house or use a lamp to verify you
are getting power.
TWO: Also, check the line cord. Wiggle it near the molded ends which is where the greatest of open circuits happen.
THREE: Unplug the tv for 30 minutes and try again. This will reset the power protection circuit.
FOUR: If all above does not get you anywhere, then the problem is
likely an internal failure of one of the key sections of the tv. The
power protection circuit is constantly monitoring the current drain and
shuts the set down when too much current drain is detected. Culprits
are the deflection circuits (including the high voltage generator call
the flyback in the horizontal deflection amplifier), audio amplifier
and main power supplies.
FIVE: This set is getting along in years. If the problems turns out to
be an internal failure of one of the sections above, then replacement
of the set may be the better choice. If you must replace the power transformer, for example,
in your set the cost will be upwards of $200 to $250. Replacement of
the flyback will run around $100.

You need to replace the "Lamp" check Google Shopping for pricing. Enter your TV model # and add the word "Lamp" Make sure you get a Phillips or Panasonic lamp don't get a Chinese knockoff. They don't last!. Hopr this helps.
I have a 36" Panasonic TV (manufactured in 2004) that suddenly stopped working. It was working fine up until I turned it off one evening before going to bed. The next morning, when I went to turn it on, NOTHING. No power indicator light, NOTHING. I'm a big "do-it-yourselfer", so I took off the back cover of the TV case and discovered that it was just a burnt-out fuse. It is a small "snap-in" glass fuse that should be mounted to a circuit board near the area where the main power chord enters the back of the TV. I found the replacement fuses at Radio Shack. The fuse came in a package of 4, for $2.99. Cheap fix and works great! The biggest problem I had with the fix is that the TV weighs 386 lbs., so I had to get help lifting it out and back into the entertainment center.
*This was posted in another thread as a solution to your problem, it would seem that this procedure is for the TV savvy, and I would not recommend that you do this procedure, and that you bring it to a TV repair shop. Or if the TV is still under warranty that you turn it in. But if you are planning on following these instructions I wish you luck, and make sure you follow them to the word so you don't mess up your TV even more.
Found that the thermistor/temp measuring device is suspect, noresistance across legs. There is a label there that says F701 seeservice 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 backpanel, etc. Also think I had to splice in the fuse or something. was awhile 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
We played Wii sports and fit for few hours than tv started to flicker and change colors to green and black and white. We shut down Wii and not TV screen doesn't show any picture. The power is there and the sound... but the screen is just blue. Any one experienced anything similar?
