is it a constant blink, or does it blink a nummber of times in between payses? Let me know the number of blinks. Please respond to this same post so I have access to previously posted info.

just got back today for same problem. convergence went out. took to repair shop. $200 part plus $60 labor. second time in a year convergence went out. was told it will happen again.

Your symptoms sounds like a damaged convergence IC.
There are two and large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110, and they are located on the signal board (on the left as you look into the back of the set).
What happens in the Panasonic set is that the convergence IC’s will short and cause the power supply to shut down from the overload of current. Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.
There are also two resistors on the front of the board located in the middle that are fusible link resistors, these should be checked for opens and replaced if they are found so.
I would suggest that you contact a service center in your area for a complete diagnosis and repair, as this type of repair can get a little tricky. But if you want to repair the set yourself, just remember to be careful. The capacitors and CRT’s can hold a charge and may shock you.
If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.
I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.
You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.
I hope this information allows you to resolve this issue.

Three blinks is short protection in this model.
98% chance one of the protect resistors around the two STK-392-110 convergence chips is bad.
Good news here----total parts cost would be under 25 dollars on EBAY. I use a seller there.
I also have start to finish, step by step instructions for this repair in this set.
They tell you everything you will need and how to do the repair.
Let me know if you want help or the instructions--I can tell you how to look to see if the protect resistors are bad.
This is a very common problem and I have fixed hundreds of these sets with this problem.
If this information told you something you did not know, rate this solution as very helpful as I do this here for free.
If you need more help or want the instructions let me know, we will find a way to get them to you for free.
