Hello and sorry you're having problems. I may be able to help, but I need to ask for more info.

1) How long have you owned the set for?

2) How many groups of blinks are there between pauses (for example: 7 blinks, 7 blinks, etc.)?

Do you need assistance with this?

Expert:  Aric replied 1 year ago.

The light blinking on the set is an "Error Code" used by Panasonic to determine what has failed in the TV. If you can get me that code (for example, the light blinks, 7X,7X,7X, or 10X,10X, 10X, etc.) then I can narrow down what is wrong with your set.

Without that code, there are many possible failure points on this TV.

The power supply is a common cause of this problem. The capacitors on this board can swell and bulge due to receiving a surge, and can cause a voltage drop on one of the outputs on the PS. This typically will cost you $150 to have repaired.

The other very common issues, are problems with the Sustain boards failing. They are responsible processing the Plasma display and are common failures for this type of TV. The voltages need to be measured by an experience professional between the power supply and these boards, and also from the boards to the Plasma Panel. Average cost for this type of repair is around $450 parts and labor.

If these boards test good, then the problem is the Plasma Panel itself which will mean you need to get a new TV. The cost to replace the Plasma panel will exceed the cost of the TV itself, as the panels are very expensive and very labor intensive to replace.

I wish I had better news, but the set will require component level testing and replacement in order to function properly again.

If you're not comfortable testing voltage or working inside of electronics, then you can locate a tech using the link below:
