    I have a Sony Vail SVE1511BGXS. I'm not finding an F2 fuse. I've found F1 (on the back of the mb) with TN on the top of it and an F5 fuse also with TN on top of it (on the front of the mb). Am I just missing it or is one of these the offending fuse that has dimmed my backlight?

    Hi,

    I've been given a Sony laptop, VPCEB4C5E (Model PCG-71211M) where the battery was left in whilst screen was replaced; suspected blown fuse.

    I think I've located the blown fuse but was hoping you could help confirm?

    Many thanks!

    I must say that this forum and this particular post have been a great find. Having already sent 1 replacement screen back and parcelling the 2nd up to go back tomorrow, I thought I'd try 1 last Google search :)
    I have a Sony Vaio VPCEA4S1E (PCG-61211M) with the same problem. New screen in, display like you're watching it through a pair of dark sunglasses.
    Fairly confident that this will be a fuse issue. If I post up mobo images, could someone please identify which component is at fault?
    Also as a complete novice, what do I need to do to fix it? Solder a wire across it or something else?

    ***UPDATE***
    OK I found a video on YouTube (even though it's up incorrectly as PCG-6121M). It identifies the fuse as F15.
    I've dismantled the laptop and solder blobbed the fuse. Trying to get a micro fuse is as rare as hens teeth. I had no alternative. Anyway the screen now works.
    However... having solder blobbed on the motherboard, is the laptop now a fire risk?

    Hi. I have a Sony Vaio Duo 11 SVD112A1SW that had a cracked screen, I have replaced the screen with one from another Vaio Duo 11 but the backlight is not working. Can anyone identify a fuse amongst these pictures?

    Cheers.
