Hi,

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.

Goodluck,
Please don't forget to rate me as fixya..

    The only solution is to call a technician and get it repaired so that you don't face any problems in the future..
    There can bee reasons for the TV not turning on.There are many circuits which may have burnt.

    If you have any other problems please ask me..

    Do you remember what was the last thing you did on your TV before it stopped working? Has the TV experienced any power surges?

    Try leaving it out of the power more than 30 minutes. Try a few hours.

TV has no power


Someone would have to check for short starting in Horizontal output circuit at the output transistor--voltage checks will also narrow down where likely problem is at.

If power light does not come on usually trouble is at fuse or very near it.

My tv fuse gets fused of so far i have fixed 6-7 fuse but it fuses off with spark/light


Get it to a service because you have a short-circuit. It will burn every new fuse.

Green light blinks.. wont turn on.... standby pwer appears normal.. ihvt and hor output check fine


*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
