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.

If you open the back,look at the can shaped items.If any of them have the tops bulged out,they need to be replaced.This should solve your picture problem,unless there is something else wrong.What is happening,is they are heating up,and the picture goes out.I bet the longer you have the TV off,the longer it stays on?Hope this helps.Thank You very much!

in protective mode the tv does not turn on and light is blinking, typically we must proceed by elimination as some faulty sections are preventing the tv to switch on. unplug the output power connectors from the power supply until the latter stop clicking. if it is still clicking after every of the output rail have been disconnected, then the power supply itself is faulty.
hope this helps!

How many blinks is the LED showing? The number of blinks correspond to a service code so that technicians can better diagnose the faulty component inside.
I'm doing factual research for a potential class action lawsuit regarding these "blinking lights of death" problems that the Panasonic plasmas are showing. I'd like to hear more about your experience. It's been a while since you've posted here. Have you contacted Panasonic? If you're willing to share your story with me, please email me at firstname.lastname@example.org.
