Good Day!
I have exact same problem after replacing cracked screen, I have x1 gen 2, almost the same smd fuses, for me the fuse F7 was blown i replaced it but still black screen and the fuse is blown again right after replacement, Can you read the number on that 8pin IC next to the fuse something like F28 or something, i need to replace it but couldn't find the part number as i can not read it, I think it is the power regulator or driver for back light. i checked all surrounding parts like diodes and capacitors all good only the fuse is blown which is connected direct to this IC, so i think it is short or blown, i see picture with torch on screen but no backlight,
thanks
