SOURCE: Panasonic Plasma TH-42PX60U, got a power surge.

Hi


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.


Thanks
Rylee

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!

SOURCE: (panasonic TH-42PZ77U plasma) the tv will power on

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 kiaeger@levjen.com.

Why is the orange power light stay on Panasonic plasma tv is on and have no picture?


It means you don't have it set on "power saver" mode. It is showing you that it's plugged in and ready. Go to settings, find "power saver" and turn "on".

Plasma tv picture not coming on and power light flashing


Yes, you have power supply issue.
the power on circuit is malfunctioning and the flashes is the indication that the voltage levels for the power on regulation is not correct therefore shut down to protect the circuit from further damage. You TV unit needs servicing by an plasma TV specialist.
Also check to see if you do not have the TV in sleep or hibernation mode.
