Fujitsu AH512 No backlight

[liamoc74]

I have a fujitsu AH512 with a broken screen, when i took it in it had backlight but screen was cracked - routine job so I ordered screen and replaced, put back together and no backlight, checked old screen again and no backlight either!

Has a fuse blown.??

Ive done some looking and the AH530 has an F4 fuse that causes backlight failure - is this the same on the AH512.?

Ive stripped it completly at this stage and looking around where the LCD connects to the board, i cant see anything labelled F4.?

Anyone had similar prob or know where i start solving this one..?

Cheers

Post good macro shot around connector from both sides of mainboard. F4 it should be.

As you have a different board, It may not be F4, It could be any number with the F in front as in F101 or F2, or even may come like this, PF101
But there is nearly always the F, can you post a picture of the Area around the lcd connector
BTW this failure usually happens when you leave the battery connected when you change the screen
