Question about Panasonic PT-40LC12 40" Rear Projection HDTV

TV will not turn on just green blinking light

Replaced lamp in my projection TV about 2 weeks ago and was working great then all of a sudden first the picture went out and a few seconds later the sound went out and the red light was flashing, tried to turn TV back on and all I get is a green blinking light. What could be the problem as I don't see that it is the lamp.

If you paid a low price like $20 to $60 for the lamp it may not be an original replacement and may have failed.
But another thing it could be is to check the lamp cooling fan(s) where you might have to take some of the TV apart to do it.
If they have lots of caked on dust it would kill a lamp due
to inefficient cooling.

You very well could have problem with the Ballast board that powers Lamp or your Lamp Fan maybe defective and if you need orinagnal hand unit for set Call Encompass Parts Distrubtion or Go to their website type in Model number they will list Parts /Prices for your model.
1-800-638-3328 Mats Electronics also sells handunits .To reset timer
Hold VOL- on front of TV and Menu on hand unit at same time for 5secs
if this does not work try it in reverse Hold Menu down on TV and Vol- on hand unit. Check your Lamp Fan see if it quits running while turning set on,if it starts and stops it is defective, other wise Follow wires that Lamp plugs into it will connect to Ballast board that powers Lamp CK it Problem M/B Ballast Board.

The TV keeps shutting off, then shortly after turns back on, then shuts off again... Plugging the cord into a different wall outlet doesn't solve the problem. Please help! Thank you

I'm having the same problem. My TV will play for for awhile and then it just dims down for about 1 to 2 minutes then powers up again. The green light stays on doesn't blink at all, and there is no red light that comes on or blinks like when our lamp went out. We replaced the lamp about 6 months ago and it's been working great until this week.

I would suggest it is a ballast problem. You can check supply of 5 volts to ballast's small 5 pin connector (trigger voltage) and about 300V-330V to large 2pin connector. If both voltages present at the start and lamp is working with in another TV - it is bad ballast.

Turns on and off green LED flashes until TV turns back on.

this is a symptom of a bad lamp. for some reason it won't spit out a lamp error. shaking up the lamp will sometimes fix temporarily but you will find replacing to be the answer. if your tv has a fan error, you will get 4 red blinks.
