Pt456c12 wont come on blinks green at the on off light

We turn it on and the green on and off light just blinks on and off but the tv does not come on we hear the fan but no picture, we had moved it to another location when this started. the lamp looks good and is not too old. what do you think could cause this? how do I tell if the lamp has gone bad or could it be another problem.

I had the same problem.  I fixed it replacing the thermal fuse.   You can get the thermal fuse from Radio shack.   Hope this helps.

Good Day, teagues;
It sounds like a bad lamp. Lamps normally have a 5,000-hour life. Looking at the lamp can tell you if it’s bad if it looks burnt, but not always. Your Panasonic TV is also known for having failure of the ballast, which turns the lamp on. 95% of the time it’s the lamp, trouble shooting the ballast is a little more challenging.
The lamp replacement is a very simple process; instructions are in the TV’s owner’s manual. Call the factory, they will send you the lamp to your home with complete detailed instructions.

Good Luck, Big Irish.

The red light is key to your issue---is it blinking in a sequence--constant blink or for example 3 blinks, pause and 3 blinks?

I have a Mitsubishi WD-62525 HDTV that suddenly wont turn on. Just has a green blinking light when you hit the power button. Any ideas?


I found this on another website, most likely it is your power supply capacitors.
  1. Press the "reset" button and hold for 10 seconds .... Does TV turn on and blinking green light turn to solid green.

  2. Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours..... Does blinking green light continue upon plugging in the TV.

  3. Disconnect ALL devices from the TV; DVD, Tuner, Cable Box, unplug the TV for various duration times .... Does blinking green light continues upon plugging in the TV.

  4. Press Power and Menu buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.

  5. Press Power and Display buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.

  6. Insure that no front panel buttons are inadvertently stuck in an "engaged" position.

Diagnosis: If none of the above test resolve the issue, then the failure lies in one of the following:

  1. DM Module Capacitors have FAILED.
  2. DM Module is defective.
  3. EEPROM Board failure
  4. Power Supply failure.

Red light blinking shows some kind of internal problem during circuit check and protection got activated upon some failure.
Count the red light blink as you will see 3 second long pause and post it here to diagnose what section of tv got problem.
Did you replaced its lamp in last 2-3 years?
Thanks.

The green light on front of tv keeps flashing and tv wont turn on


Howdy,

The green light blinking indicates your TV has a problem. The problem is that each Brand of TV has different codes and with out the Brand and Model number, I can not help you at this time.

Please, count blinking sequence. Model number will be on back of TV.

Recap : Provide Model Number, Brand and Count Blinks.

First though; unplug TV from power source for 3-5 minutes then plug TV & box back into a/c outlet.

Good Luck, BIG IRISH.

Please help with tv! green blinking light wont stop and tv wont turn on


Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
please post your error code
