im trying to sort a 42LE4900, it turns on does its cylon red light thing with the power led then that goes to white but nothing on the screen. no backlight and from what i can see no display. there is a click from the driver board like a relay closing.
measured the voltages on the backlight connectors to the metal back plate and get 65v red 0v black 11.5v black this is the same for all the used connector pins apart from one that reads 9.5v.
ive tried to disconnect the main cpu board as id heard it should then just fire up the leds when power is applied, but this didnt work.
