Re: Panasonic TH-42PZ77U No Pwr, Blinking 7 Times
When I unplug the SU board and turn on the TV as the tech manual requested the screen turns on and I can see the menu. But I can only see the bottom half of the screen because the SU board is out. If the panel was bad would it power up and the screen turns on? As soon as I put the SU board back in the screen does not turn on and the power light flashes 7 times then pauses and repeats. If it is a buffer board how do I figure out which one?Leave a comment:

Panasonic TH-42PZ77U No Pwr, Blinking 7 Times
I have a Panasonic TH-42PZ77U; I am experiencing the 7 blink power issue. I did the usual troubleshooting by trying a new outlet and unplugging all the cables from the plasma. Then I downloaded the tech manual and went through the troubleshooting steps. When I unplugged the SU board the TV powered up so I ordered an SU board. When I installed the new SU board the same thing is happening. Could the SC board be frying the SU board when I power it up? Your help would be very much appreciated.
