Long story short I needed a replacement LED LCD for my thinkpad x220. I left the battery in when swapping lcd and it blew a fuse or so I believe. There no longer is a backlight, the screen is almost black, but I can still see a faint startup logo.
I looked online for a solution and found out that people had the same problem and suggested using a solder ball to connect the ends of the fuse together as a temporary fix. I tried bridging the suspected blown fuse with solder, but it didn't work. I also managed to break off one of the capacitors(?) in the process. The computer still works but still no backlight and I have no idea what that the broken capacitor or soldered fuse will do. I really need this fixed but I don't want to buy a new motherboard yet. I am really hoping this is repairable. Would something like this be possible to repair for a computer shop? I'd really prefer it to shelling out $$$ for a new motherboard.
Attached are the pictures of the bridged fuse. The fuse is marked F15. Although I don't have a multimeter I thought to solder this one because the LCD cable port on the motherboard was encircled and labeled F15-2Amps-32 Volts very clearly. They also printed the volts and amps and labels of other fuses from f11-20 etc.
Of course didn't work so now I am left with a soldered fuse, broken off capacitor(?) or whatever that small piece is, and no backlight on my lcd.
To clarify, I know its the motherboard because I have 2 replacement screens plus the original cracked screen that should all work, and all of them are dark. I also have 2 lcd cables that both don't work, so I am confident its something with the motherboard. I really need this computer.
Here is the picture of the solder ontop of the f15 fuse and the broken off capacitor.

The quality is bad but I only have a phone. I hope this gets the message across.Is it possible to solder a new
