hi usualy the screen will light for about a second or so if this is the case you need a new inverter panel this is generaly a lond board with a line of transformers situated on the left hand side of the rear of the screen  although in some cases not sure about this model but you may have two smaller panels either side which are a master and slave inverter .are the back lights lit at all ??

Hi.Check for faulty circuit protector on the screen drive panel (T-CON) it usually provides 5 volts to the panel.
