There is only a backlight fuse. There is no screen fuse. There is either a problem with the screen, or one of the components on the motherboard. Probably the IC that is in charge of video.

Try checking component ic4104. That's the backlight driver and is located in the 11,C quadrant of side A on a TA-085 v1 board. The part number is TB62752BFUG. Test each connected capacitor to ground in continuity mode with a basic multimeter for a short. If one or more of the capacitors are shorted remove those and check the pads where the capacitors were. If there's still a short on both pads where the capacitors were then put back the original ones. Odds are if there's a short to ground but doesn't go away when you remove the capacitors then TB62752BFUG needs to be replaced.
