    Yes I'm 100%, I replaced a cracked LED screen just few days ago and the backlight was out on both new and old screen, this is driving me crazy as everything works but the backlight, I can see the images with a flashlight up against the screen and it's LED as there's no inverter and the model number PCG-71811W VPCEH26EA which only come in LED option

    wow, amazing thread just fixed my friend's vaio vpcej28fx. Same problem with blown f4 fuse, after lcd panel replacement, fuse had big "H" on it, bridged it with solder - boom worked like a charm. Thanx to everyone!

    It could be the one.
    If you have a ohm meter, you will find out.
    It's also worth a try.

    Hello!
    I had the same problem and used the bridge to solve. I really appreciate everyone's help. My notebook is VAIO PCG-61411L
    Now I wonder where I can buy the fuse N to do the job the right way because if it's there is because it has some utility.
    Thank you!

    I've got a Sony VAIO VGN-TZ31WN with the same problem. I've just replaced the LCD panel and have no backlight. The screen works perfectly well on a similar TZ computer so I know it's not a fault with the screen panel. There are two options I can think of - either the hinge switch is sticking down or the the fuse, as mentioned above, is blown. Problem is I can't find either!

    Anyone help on this, especially the hinge switch as I can't believe I cannot find it, on most laptops they're obvious.

    You should have a steady hand to take a picture.
    Those blurry pictures like these are really hard hard to see.
    However, the small green one in the last picture could be the one.
