    Sony Bravia XBR-65A8F, no turn on

    TV does nothing when turning on, if I do a power/-vol and then plug in I have a solid green light but nothing else. I purchased a harvested Power supply and Logic board. Installing the PS had no changes but the Logic board gave me 1 white flash an 4 or 5 repeating red flashes.I tried a firmware update using the update file 3 times with 3 recomended files, no power, insert thumb drive and and power up, nothing happened.
    Board vendor says board is bad and will provide replacement but does not have any. Sony want $500 with $150 core refund.

    Am I on the right track or should I be checking something else

    TIA

    Forget all the above, the Tcon board connectors were unpluged. Once I plugged them in the mother fired right up
