The power supply board seems to have died. If its under warranty, check with Panasonic. If not, whats your nearest electronics repair shop? Just make sure they dont charge you an arm and a leg.

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!

Panasonic plasma TV TH-42PWD7 blacks out..


These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs. Pull up older posts. Check the site in 'Mosaic' view. It will make search easy. http://electronicshelponline.blogspot.com/

TH-42PX60U red light blinks 10 times wont come on


On a Panasonic TV the 10-blink error code can sometimes be caused by low voltage running through an HDMI cable, particularly from a Media PC or some video game consoles. Try disconnecting any HDMI cables and unplugging the Television for 30 seconds, then power it on without the cables attached.

If this works, connect the cables to the front panel (usually HDMI-3) which uses a different controller board.

Picture and Sound flash from 'on' to a black screen


Hi, The problem lies within the unit. You have a hardware failure within the board. The power supply board needs to be repaired or replaced. If you are a handy person, you can easily swap the power supply board.. If not, bring it you to local reapir shop, they will find the parts and replace it for you. I wish I had a better solution like an easy fix for you. Sorry, but on hardware failure, there is no easy fix. Thanks, Mike
