I don't know where it is on that motherboard. Usually people replace the boards, but fuses can be changed. You need better equipment than a simple soldering iron. I usually tell people that I have the minimum equipment to do it. I have a quartz preheater and a temperature-controlled rework station. Some shops do that kind of repair, but it is often too expensive to be practical. There are often 2 fuses affected. There is a 0.5 amp that controls the LED status lights and a 2.5 or 3amp fuse for the backlight. They are often very near the LCD connector.
