Pioneer Plasma 111FD To Solder or Not to Solder.

[pixelcap]

Hello out there in Badcap land.

I have a Pioneer plasma that gave me the dreaded 8 red blink and shutdown, I have been trying to trace the failure points. On my last inspection while replacing a Y Sustain Board I noticed on the original and replacement board some missing solder, the points of connection
are from the Digital Address Board and the Buffer Boards. I have included the pictures, should I resolder these points or are they unsoldered intentionally? Any help would be much appreciated.

Thank you

No those are not used.

I went ahead and put in a new Main Board along with the original Y S Board, the same problem the plasma powers on for two seconds then I see the screen energizing then the shutdown, and 8 red blinks. I'm going to put the cover back on
and put this old girl to sleep maybe I will pull it out again and try a component individual repair of the lower buffer board which I think is causing this problem.
