Hi, i had a issue with my display (MacBook Pro i7 mid 2012) and i took to apple repair centre thinking it was a display problem because the screen was black and all other things were working properly. But it was discovered there is a fuse (or other name I don’t remember exactly it’s name) damaged in logic board which “gives” bright to display. Which I think it’s true because if i put a strong light in Apple’s logo i can see things in display. Then I realized how expensive is replace this part and i was looking for alternatives. I found a site (powerbookmedic) which says i cand send this board only to repair. It’s half price of take a new logoc board from Apple, but does it a good option? Has anyone had a similar problem and took them to repair? What to say about repair a logIc board? Thanks Update (07/20/2017)
This is what shows
If you can see your desktop icons using a flash light then the backlight fuse link or the WLED driver is burnt (or both). Yes, you’ll need to find someone who has the skills and access to the needed parts. PowerBook Medic is one option.
