Dell 7450 Backlight Issue

Hi!

I have a 7450 which suffered some liquid damage. The good thing is it still works and when plugged into an external monitor everything is hunky dory.

However, without an external screen the picture is barely visible. I thought the backlight had blown so I changed the screen however the replacement screen had the same issue?

I've read it is something to do with a fuse on the motherboard, is this correct? The replacement screen had the electronics bar (invertor?) as part of the screen but I did not change anything else.

Any help/advise would be much appreciated!

Thanks

Hi Windowscrashedagain

Thanks for writing to us. 

Do provide us your system tag#, email address and name via private message,by clicking on my name in blue and then select send a private message

Please provide us the LCD part# you replaced? 

If the issue is still the same with new LCD, probably the LCD connector on the motherboard is gone. In which case we have to replace the motherboard.
