    Panasonic sc boards TC-50GT30 & another Pan 50"

    Hey guys I have a couple panasonic plasma TV's with bad sc boards. I have replaced the IGBT's on both boards(the ones that were shorted). When I power them back up they both end up shorting another IGBT on the board.
    I get using fets/igbt's to power up a transformer but I don't understand the theory behind what these "switches" are doing?
    Maybe then it would be easier for me to figure out the issue I am having.

      Re: Panasonic sc boards TC-50GT30 & another Pan 50"

      What did you use to replace the orig. igbts with, and where did you get them.
      There are a shitload of fake parts being sold on ebay.
      There are quite a few threads about this model and its known problems such as Q660/Q661/ ics and their drivers. DO ALOT OF RESEARCH! Read every thing about Panasonic plasmas posted. You may have a bad buffer board, read how to check them and isolate them from the sc board. Read up on the SC50.

              I did use IGBT's that had a higher voltage rating....otherwise they were very comparable....
              Thanks for the links!

                  Three 820-01700 32GB Logic Boards Same Issue: Won't Wake From Hibernate
                  by ugamazing
                  I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!

                  We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre...

                  Panasonic plasma A boards/Kuro media box repair.
                  by Erik Masters
                  Hi all.

                  I have 2 Panasonic plasma A boards for ST50 50"/65" and Kuro KRP 500A media box which needs repair.
                  I'm not good enough at component repair so I need some help.
                  A boards and especially Kuro media box is still very valuable and I can't throw it away like some average Joe,lol

                  I'm from Europe/Slovakia and I'm searching for someone who is willing to repair these things or some tips at least.

                  Both A boards have HDMI issue either no signal or flickering.
                  And media box possibly with voltage regulator issue which is common...

                  Panasonic TX-P42UT30E, IGBTs on the SN board
                  by rivetcity
                  Hi,

                  I'm having problems with my plasma Panasonic p42txu32e. The issue started about 12 months ago.

                  I have a remote controlled main outlet so whenever I turn off the TV set at night, I also switch off the whole power outlet.
                  It gives me a better feeling to know I don't have 230V on any cables, so my dog can't get hurt if he gets the idea to start chewing on something.

                  About 12 months ago the TV started to have the following problem: when pressing anything on the RC to get it on, the red led would go off.

                  Sometimes it would turn...

                  Panasonic TC-P65S2 SU or SD Boards Bad?
                  by midnightg35x
                  I have a TC-P65S2 that blew an SC board (I had a previous post about some cross references). When I put the repaired SC board in, it worked with the SD and SU boards isolated and SC50 jumped. I reinstalled the SD and SU boards. I did forget to remove the SC50 jumper, but from what I understand about how that jumper works, that should not cause SC board destruction with properly working SC/SD/SU boards. When I turned the TV back on, the SC board blew again. Based on the fact the SC board was working without the SU and SD boards, it at least makes sense that one or both of them is bad.

                  Panasonic TC-P55ST50 8 blinks then no blinks
                  by Andre Gilbert
                  Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
                  Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.
