Guys,
I have a Panasonic 50 plazma tv. I have had it for about 2 years now and last week I got the 7 blink of death. I looked all day on monday, called many shops and they all want 450 just to look at TV. Saying it could be many things.
So me being the fix it myself kind of guy, not good idea at times. Well I never could find the manual, so I got on here.
This is what I did and how I got to where I am at. I first took the tv off the wall mount, do not do this alone its a killer. I have the full range mount, so pain let me tell you. Back on track I traced the power board wires and seen what was all connected. I then started disconnecting 1 by 1 the big boards. The one on the right gave me 10 blinks. so i plugged that one back in and went to the one on the left. I lifted the power from the SC board and my power light stayed on. No more blinking 7 times. I then went deeper in and removed everything going to the SC board. With nothing hooked up but power to the Sc Board I still got my 7 blinks. So I ordered the SC board it showed up and I installed the board. Turned on the TV and it set me up through the program installing of tv.
My box on the channel area are white and the picture of TV is snowy white and red at times. I can see all the sections of the tv at times. Left area right area channel box, ect ect.
From finding the service manual online finally and have the troubleshooting manual I think I am to the point of ordering the D board.
I have both led glowing on the board for the SC and SS, I have a 15.8 volts at p6 pin 1 and 3. I have done factory resets, the self test show all boards ok.
Where to go next beside shotgunning and changing out D board. Any help would be super awesome. Thanks
