SOURCE: panasonic th-42pz77u 42ed

Pin 93 of the MPU IC9003 monitors the status of the SC, SU, SD board. During normal operation, the photo-coupler PC6480 outputs a low to pin 93. If the SC, SU, or SD board becomes defective, a high is provided to pin 93. As a result, the unit shuts down and the power LED blinks 7 times.

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!

SOURCE: power light blinks, but tv won't come on

I have the 52" version of the Viera model. Mine went out last night and started blinking twice over and over again. I suspected overheating so i just went to bed and tried it in the morning with no luck. Then I unplugged it for more than ten minutes and plugged it back in and everything worked fine. I hope this helps.

SOURCE: panasonic th-42pz77u has no picture.power light

seven blinks on this model is the SC board. it will need a new SC board and the software update for the new board. usually only authorized servicers have the software need to do the upgrade. but if you were to contact panasonic then they might be able to have it fixed for you for free since this was a defect in manufacturing. of course this depends on how long you have had the tv.

Panasonic Model TH-42PZ77U doesn't turn on


I contacted Panasonic and it seems that they will take care of the problem even though the TV is out of the 1 year warranty. They are aware that this is a manufacturing defect, apparently. I'll follow up later to let you know how it turns out.
