Dark LED screen, very faint picture

Hi there,

I have a Lifebook AH502 which has a very dark LED screen.

If this was an LCD screen I would suspect the inverter board, but seeing as it's LED is does not have a seperate inverter board.

I have replaced the LED screen with two new ones, each one showing no improvement.

I have replaced the screen cable with a brand new one and still no improvement.

I am led to believe that the culprit is a blown fuse somewhere on the board either near the LED connector or the DC jack.

I would be forever grateful is someone could upload a pic of this board with the offending fuse circled so that i might replace it.

thanks
