Your Set is going into shutdown mode due to the convergence section of your television. Thats what 3 blinks mean. It could be just the Convergence ICs and resistors or you may need a new Signal board TNP2AH035 Let Me know if you need further assistance with this problem.

Power on the set, listen for afaint buzzing sound as the set tries to fire up. If you do not here it then your lamp driver, or ballast is most likely faulty. Also make sure you have the door and all covers back in place and secure. And make sure you insatlled an orginal panasonic lamp because some generic will not work.

It very well could be the ballast. I unfortunately have this tv and keep extra bulbs because they go out about once a year. Last time when I replaced the bulb the tv blinked and the red lamp light flashed like it does when the bulb is bad. Ballast repair kit fixed it up. This is certainly a design issue but you'll get no help from Panasonic. If tv comes on the goes out after a while, clean the fan filter.

If the front power light is blinking three times then your TV has a problem with the convergence. You can get the correct replacement parts and full step by step photo instructions from www.TvRepairKits.com

I have a Panasonic PT-50DL54 50" rear projection tv. My tv screen won't come on but the fans will. The power led light flashes green like normal but than starts to flash fast for about a minute than the...


Time to get a new TV. I have similar problem. In my case, the set turns off, LED blinking green for about a minute or 2, then the set will turn on by itself. Something the LED started to blink yellow after blinking green and then shuts off. I can turn it back on. This happens 3 or 4 times in an hour. After that, the TV stays on for as many hours as I want until I shut it off.
And then the problem repeats everytime I turn it on from a cold start.
I have my eyes on the 50 inch Plasma from Panasonic. Bestbuy has one for 999.99.

It looks like a problem with a tube (projector light) I suspect the green one. Pay attention to flickering on the lights and post me the results.

PT-45LC12 Problem after startup


When the lamp flashes 4 times this is what the error code means IC 2301 pin 11 has detected an LCD error which is caused by an error in the LCD power CBA. which means the lamp voltage has become more than 130 volts or less than 30 volts. Or the lamp current is more than 5 amps, or the lamp is cracked. Its one of thos 3 reasons that will make the lamp indicator blink 4 times. Hope this helps. If you need the service manual for this model you can get one emailed to you from the following link.

PT-45LC12 wont power up


You have a bad lamp. The "clicking" sound you hear is the ballast (lamp power supply) attempting to start the lamp. The warning on Panasonics that comes up on screen does so when the life expectancy of the lamp is approaching. Otherwise your "clicking" sound and the red light on front are saying bad lamp. When you replace the lamp remeber to follow the instruction that Panasinc provides with the new lamp on restetting the lamp timer. This is usually done with the volume down on the TV and the PIP button on the remote.

Tv keeps turning off


If it's staying on for just a short period of time it sounds like there is a sensor that is giving the unit a faulty condition (Perhaps for reason or due to a fault in the sensor). There are normally a few temp sensors in the TV around the Lamp and Ballast. They may be bad, or the lamp or ballast is just generating too much heat.
