Panasonic TC-P65S2 issues money pit

[Philip18360]

Hey guys and girls I have a tc-p65s2 I got it for free I knew it did not work. When I got it home and plugged it in I got 7 blinks I disconnected the sc board and I got 6 blinks. I ordered a sc board off eBay and put it in it powered up for less than a minute and shut down and I got 7 blinks again. This time I ordered su and sd and sc put it in tv powered on I hooked up my laptop to hdmi and I had a lot of pixelation all over.. I switched my laptop to 1080i and the picture cleared up. So I was super excited put the back cover on me and my wife carried it to our bedroom. I was watching the tv and fell asleep 😴 when I awoke this morning the tv was off blinking 10 times so I unplugged it and plugged it back in and it powered up for about 10 minutes and shut down and blinking 10 times.. So I unplugged it again and waited an hour or so now when I turn it on I get 7 blinks again.. I already spent close to $350 for the parts any suggestions on what I should do next it has such a clear picture when it works. Should I dump more money into it or should I just dump it? Any help is greatly appreciated.. Phil

One of the reasons some of these boards go out is due to improper grounding. Are you making sure that every screw is securely screwed in? You don't need to tighten them like a mad man, but make sure its snug.
The pixelation is strange, I am not sure what was going on there. Have you had a chance to look at the voltage output from your power supply board? Back in the older hitachi plasma TV's a few models were infamous for blowing IC chips on the buffer boards, and I don't know it is true or not but I was told that it was correlated to bulging capacitors on the power supply. I never got into Hitachi so I don't know if its true but it's possible your power supply is causing the failure. I don't know enough about this model to give you facts about it, but I figured since no one had posted an answer yet.
I look forward to seeing how this one turns out to be.

Here is a panasonic guide I got it works for most models of plasma.

Hate to just stab at a guess but it could be your panel killing the buffer board. the sparkles is one of the signs. It also could be as simple as a bad connection. Also to confirm what Nick already said Panasonic plasmas are known for losing ground connection thru the screws. if you wanted to spend the time you could remove the board and look for evidence of black burn marks where the screw screws in or where the board makes contact.
