    I am trying to diagnose a fault on this tv where upon power up, relay clicks, screen flickers in a split second and stays off with no backlight. There is no faint image, the internal Onboard led signals system startup failure.
    Disconnecting one connecter from the power board connecting to the y - main and the x - main respectively has no effect. The powerboard pinouts to mainboard behave normally whilst load applied, same as to y - main .

    Any help in further diagnosis would be much appreciated.
