Dim Laptop LED Screen – F1 or F8 Fuse just below the motherboard video connector | NWA PC Help

For those looking for assistance on finding the fuse on Various models, Please provide photos near the LCD Connecter, but also near where the power charger plugs in. I am seeing the possibility that some fuses may be located over near that area.

This applies to Dell, Sony and many other manufacturers of laptops with LED based screens.

These issues are also commonly search on as no backlight.  In most cases when you know the screen is good, it will be a power issue from the motherboard causing the backlight to fail to power up.

On the motherboard you should find a fuse labeled f1 in the case of dells, that is approximately .8 mm in depth, and 1.55 to 1.6mm in length. This fuse protects the voltage circuit to the led’s. in the case of a dell inspiron 1545, it is a 3 amp, 32v fuse, that can be replaced relatively cheaply. Make sure tho that you have isolated the cause of the fuse blowing. Good luck!

The Fuse is located on the Dell Inspiron‘s just below where the led video cable connects to the motherboard.
Use a Continuity Tester or Multimeter to confirm whether or not it has blown.  If you find any other fuses or different locations, feel free to comment, or even link to pictures of other fuse locations and I’ll approve them.

For other manufacturer’s the location is not so obvious unfortunately.
