3 Blinks on the LED red power light followed by a 1.5 second pause, then another 3 blinks followed by 1.5 second pause. It keeps repeating the above. What is wrong?

This sounds like a main power board issue. After you unplug it, it will work? Are you planning on trying to service it or having it serviced?
Thanks,

3 blinks is the error code for the convergence ICs. You need to replace both STK392-110 convergence ICs. You can get replacement ICs at the following link and they provide installation instructions with pictures.

The 3 blinks is a error code for the convergence circuit. You can get the convergence repair kit for your model at the following link which contains both Convergence ICs and all six feed resistors and they include step by step instructions with pictures that show how to do the repair yourself. Heres a link to the proper kit for your model Panasonic.

3 blinks is short protection on this model---98% chance one of the two STK-392-110 Convergence chips it uses has shorted.
If you unplug set and look inside you will find two black chips that have that number printed on the front of them in white letters. Right in front of them you will find about a dozen light blue resistors---most are marked 2.2 ohms---look if you get a chance---if even one of those resistors is white in the middle (discolored) you have found your problem.
Both chips and any bad resistors need to be replaced.
The repair involves getting at the parts and replacing them--the chips each are mounted side by side on metal heat sinks with fins--each has 18 pins.
Most shops get 300 or more for this repair but the actual parts cost if you or someone you know can do it is under 30 dollars.
I have START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS SET. I got a notice from a lady who used them to fix the same set you have---she saved the set and a lot of money.
The instructions tell you everything you will need and how to do the repair----clearly I do not know how much skill you have---it involves soldering etc.
If you want the instructions I will post them here for you to look at and copy/ paste them. Once you read them you should know if you can do the repair------they are my own instructions based on doing this repair hundreds of times.
I will also post a photo here showing what the chips look like.
Repair takes me about 1 hour; if you are doing it for the first time it will take you longer.
I also know the best place to get the chips at reasonable price.

Well, Everything said on this site is true. I recently had a breakdown on the same type of TV and through this site and the comments left, I was able to repair my tv for less than $50. (Extra cost for upgrading my soldering iron that wasn't getting hot enough) It was amazing. The feeling when the tv powered up and stayed on. Credit goes to Howard and Chris Palmer for their comments. It is possible. You just have to commit and do it. Its not as hard as you might think. Thanks guys.
