Try disconnecting all of your HDMI cables and plugging the power cord of the TV into another wall outlet. If this resolves the issue, you may have had a small power surge from either your wall outlet or one of your source devices. It is recommended to connect your TV to a surge protector if you haven't done so already.

If your Panasonic Television is blinking 3 times then you have a short on your power supply and the most likely suspect is your convergence IC’s.
I have repaired hundreds of these sets, so if you have any questions after reading the following, please reply to this post and I will help you in any way that I can.

With that aside I have some support suggestions that I have put together that may help you make an informed decision.

You should be able to get a local service center to repair this at your house for between $350.00 - $450.00, If you want to repair this set yourself, I have some instructions below that will be a help to you.
While it is not a very hard repair, this repair can be a bit tricky


How do I tell if the IC’s are damaged?
When looking at the area around the convergence IC’s you see some resistors that have changed colors, or you test a resistor and it no longer reads the marked value. You will have to replace the IC’s and the supporting components.

When you remove the old IC's, please be sure to remove all of the old heat sink compound, as it can act as an insulation for the new IC's and cause them to overheat. I usually clean the heat sinks with alcohol and a small rag.


Where are the IC’s located and how do I find them?
There are two and large IC’s that control the convergence in a big screen set. Some of the newer sets only have one. If you only have one, it is right in the middle of the set on the center circuit board. 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.

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.

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/ , they do carry OEM or better parts, and your will get a repair kit instead of just the IC's.


I hope this information allows you to resolve this issue.
I am doing this for free.
If I have helped you, please help me, and rate this suggestion the highest FixYa rating. (Two Thumbs Up)
Please Note: If you cannot rate this post with the highest rating, then please do not leave any rating. I am doing this for free and I do not think that any rating other that the best is needed.
If you need further assistance please comment to this post and I will try to help you further.

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.

Sometimes, in the Panasonic projection sets, one of the convergence IC's shorts out and draws so much current that one of the resistors next to it glows red hot. The computer senses the extra current and shuts the set back off. This is quite an easy problem to correct, but the set should be serviced by a qualified tech familiar with panasonic projection sets.
