hi c/j if it comes on for a second then goes off sounds like the inverter do the backlights go out or is it just a dim lit screen ?

Ok,I read at the top Plasma forum so i assumed it was a Plasma,but again have you actually checked anything psu supply volts etc???,
but to aid you somewhat further its worth checking the surface mount fuse F1 on the left master inverter board.
