    You need to remove all other parts, then take out just the motherboard.
    Take a clear and high resolution photo of both sides of motherboard.
    Take the area around LVDS (LCD) connector on both sides

    I have replaced SONY VAIO VPCCA290X screen, no back light. I took the battery out while I was doing it. Then I put the old one back. it has back light. It shouldn't be the fuse problem, right? What the problem will be?

    NO, it's not fuse problem.
    Make sure you have LED LCD. If so, it's LCD problem.

    Hi, i have the same exactly problem with the vpcea24fm, got no backlight after replace the screen, and i already tried two screens and still no backlight, i open the laptop and found the fuse that you showed in the photo but it seems normal... please explain how to do the solder blob.. Sony wants to charge me $600 dollars to do that and the laptop does not worth $400!... Thanks

    Can anyone confirm if this is the fuse that is the trouble maker on my Vaio? Multimeter says its a dud and its located right on the backside of where the LVDS connector is but I need some reassurance :)

    It was the correct fuse and soldered a bridge to fix it!

    I'm surprised but it actually worked. I soldered the F16 fused with a jumper and it works. thanks for the help!

    Another success story from me, i managed to get work my vaio vpceb4l1e burnt fuse, after 2 hours of work and i found f16 fuse marked with an N sign, soldered it and it worked like a charm. Thank you... Have a nice day :)

    note: i replaced broken screen with battery on, it was the cause.

    I'm shocked how many people are replacing lcd screens with power on and/or battery installed. What exactly would prompt somebody to do such a thing?
