I had the same issue twice with a TH 42PWD5. turns out it was my UPS that was killing the switching power supply. Warranty covered it but when I removed the UPS not a single issue in 3 years.

The six blinks indicates that an internal fan is either bad ot blocked by dust or debris, You should be able to look in the back of the unit and see some cooling fans. Chances are one on them is not turning and will need to be replaced

I had this problem in 2007 / 2008 here is what happened to me.
Jan 09, 2008 - I also have brought the unit to the authorized Panasonic repair facility and the problem is a failure in the P-board which is the power supply board. The P-board needs to be replaced. The repair will cost $475 plus tax. $250 is for labor. The unit was nop more than two months out of warranty. This does not speak well for Panasonic. I have been researching the problem and it looks like this has happened to many of the Panasonic plasma TVs.
Jun 14, 2008 - As an update to my problem with the failed P board. Contacted Panasonic Service and talked to a customer service representative. I told them how I have purchased many Panasonic products and how unhappy I was with the failure of the product. They proposed paying the labor cost of $250 and I would pay for the part. I just hope it does not happen again.

Thanks for using FixYa.These kind of issues in plasma usually happens due to bad cap on any of the boards inside. However, to check what has gone bad you’ll have to open the back of the unit you’ll need to check bulged/swollen capacitors on power supply board. As the unit won’t show anything for a long time so it means that it is the power board which is causing this issue. These issues usually happens due to overheating in plasma TVs after sometime, as these sets are very hard working device and produces a lot of heat.Please do accept the solution if the issue is resolved or post a comment for further assistance.
