If I guessed correctly your motherboard model is 820-3023
If that is correct and my schematics are right it is a fuse, however it is a 3amp 32V and it is 603-HF
Good news is that, that is the main fuse for the backlight.
Not so good news: once you replace that I would definitely check Q9707 which are the transistors that open the backlight communication. Make sure they are not bad before you power your computer on, otherwise you would have to replace that fuse again. Q9707 looking at your picture same direction and everything it is the 6 leg IC chip on the right side of the fuse.
I would also check R9788, R9789, C9782, and Q9706.
