    Panasonic TC-P42U2 - no click...no blinks

    When plugged in will not turn on...no click no blinks.

    Suspect it is the A Board...what is the procedure to troubleshoot to confirm A Board is bad?

    Thanks.

    You say no clicks when plugged in. Do you also get No clicks even when you press the Power button to turn it on?

          I don't think its the PSU...fuses check good and I'm getting power to the board.

          Based on what I've read here and elsewhere I think its the Main or "A" board that is bad.

            Would anyone happen to have a Panasonic TXN/A1LJUUS / Board Number(s): TNPH0831AG main board they would like to sell?

              Apparently Main Bds for these 2009 TVs are hard to get...I am looking for a TNPH0800 2A Main Bd for a TC-P42X1....Just can't find any at all.

                    Are you getting the std-by 5V when you plug into ac?
