Plasma Board Condition - help
So I've been dealing with my panasonic plasma (2012 TC-P50GT50 woes for awhile now; gone through 4 main boards, always the same issue, ONLY the HDMI ports die, coax/component in have worked fine...see thread:
https://www.badcaps.net/forum/showthread.php?t=51318
So I utilized the PTS electronics board repair for my main board as mentioned in the above thread...however when I was hooking everything up I figured I'd give the other boards a look and found that the TNPA5670 board looked like this (pictures below).
Is this board toast? It looks like its got some really bad brown flaky stuff around a bunch of the solder joints (is it solder resin?) Can I just scrape this stuff off with my fingernail - it seems to come off rather easily. Could this be the reason I've gone through 4 main boards?
Thanks, hopefully I can get this thing running again as I loved the picture when it worked.
I haven't checked the voltages yet on the power board, that's next before I hook up the new main board, but I wanted to check on this first in case I need to order a new board. For what its worth my father is an electrical engineer and has access to an oscilloscope and tons of other electrical testing equipment (semiconductor test engineer) if anyone can point me in the direction on how to test individual boards to see which is responsible for frying my main board constantly
If my main board dies again I'm just gonna say screw it and get a new TV - love plasma's tho, wish they still made em.
