Turning on problem with Panasonic Viva PT-43LC14

I just purchased this TV from a frined about 4 months ago for a really good price. He purchased this unit about a year ago brand new and never had any problems with it. The unit was working perfect ever since i brought it from him and all of a sudden last week Tuesday I hit the power button on the remote and the TV turned on after about 10 to 15 seconds, which is normal but after it turned on it all of a sudden turned off. Now when ever I hit the power button the power light flashes on the TV which it normally did before it powered on but after 10 to 15 seconds the screen still stays blank and you can hear a like light rattling sound coming from the TV not sure what that is. I am not sure if a bulb blew or what is wrong with it. Any help would be greatly appreciated. Thank you.

Re: turning on problem with Panasonic Viva PT-43LC14

Sounds as you have a bad ballest. The ballest is the power supply that turns your lamp on. You can check your lamp by removing it and it should be clear and no broken pieces of glass. With the lamp removed install the cover and turn it on you should hear no noise and when the power light turns red you should see a LAMP red led blink every 5 seconds. If no noise then the lamp is bad. If you do hear noise you have a bad ballist. Hope this helps. Frank

Panasonic projection lcd pt-44lcx65 pink wavy lines

The problem is the computer in the TV is set to hold data for 2500 "On/Offs" Once you turn the TV on and off 2500 times, the dots start to appear as the computer cannot store anymore date. Call Panasonic, they will send a tech to your house for free and reset the computer and update it at the same time from 2500 to 1 million on/offs so it wont happen again. It takes maybe 10 mins to complete.

Hope this helps.

TV turns off after being on for just

I have the same problem and I believe the new problem is the cooling fan is not working properly and the unit is shutting down to protect itself from the heat.

How to reset the meter of lamp

You need to have your Panasonic remote.
1. Make sure the power cord is plugged into a properly grounded outlet and turn on the set with the power button on the projection unit or the remote control.

2. While holding down the (VOL -) key on the projection unit press the PIP or SPLIT key at the same time. Hold it for longer than 5 Seconds. The PIP or SPLIT key is model specific:

PIP for Models:

SPLIT for Models:

3. When the unit resets the lamp timer it will display a screen on the TV indicating it was reset to zero. You press recall on the remote to exit.

You will find a PDF of the instructions at this site:
