My Macbook pro has no backlight (you can see a dim image). I checked the backlight fuse on the logic board and it's burned out. I heard Apple recommends replacing both logic board and display to fix this issue, as the display be shorting out the logic board (so if I replace the logic board alone, the new logic board may get shorted out and damaged by the display again).
This way I may just replace the logic board without having to replace the display if it’s healthy.
How would one check the display pins for a short-circuit?
