Question about Panasonic TH-42PD50U 42 in. Plasma EDTV
Does it start blinking as soon as you plug the tv in or only after you hit the power button? Also, how many times is it blinking? Count the number of blinks at least three times

Most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you the flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.
I hope I shed some light on the subject for you.

The power supply board is dead,that the board where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

The light blinking twice means there is a fault within the system and it is a code to tell Panasonic where roughly the fault lies.
Go to Panasonic's web site and look for your set then input the fault code and hopefully they will tell you where the fault lies.
