    Looking for assistance troubleshooting a Panasonic TC-P65ZT60 with 3 LED Fast Blinks

    Hello all,
    As the title states, I followed the troubleshooting guide located here: https://www.manualslib.com/manual/23...page=53#manual, which concluded the 'A' board needs to be replaced. Looking around the net and eBay, I see that there are repair services for the board (TNPH1043UE? Not sure if it is a 'UE' as the suffix grid does not appear marked). What additional troubleshooting can be performed to ensure 1) this board is the problem and 2) since there are repair services, what are they fixing on the board?) I expected 3.3V not to be available anywhere with this code, but on the 'A' board, I momentarily found 3.3V at the LD117 regulator. I also found 3.3V again at the test points on the C1-3 boards.

    Any other suggestions for me to look in to? Thanks,

        Look at the photo. Compare it to your board for thr resistor placement. Post a clear photo of yours..

          Here is my board. It seems to be missing the "masking" to IDs the rev.

            Your board is the same as the one in my post. It is a UE suffix board.
