Hi Guys,
I have been given a 2012 13" MBP i5 which has an internal display that doesnt work. Nearly everything i find online points to the backlight fuse, however, the backlight still works perfectly (when i turn the brightness up, the screen becomes perfectly white) . Theres just no image whatsoever on the internal display. I am writing to you on this machine using an external display. I have 2 x spare logic boards (both not working but good for parts perhaps) for this model as well as a few spare cables (eg LVDS etc) etc.... any thoughts on what could be the problem?
The previous owner had the bottom cover off with the MBP still on and when he moved it, a puff of smoke came from the LVDS socket or cable on the logic board and even burnt his finger a little when he touched it.
So its obviously a short.. but what, a fuse? or some other component. Ive read HEAPS online and still don't seem to be any closer to understanding which components are in play, and even where they might be located. I have studied the logic board closely and cant find any usual telltale signs that something fried.
Any thoughts, assistance, testing procedures and even downright schooling on the issue would be greatly appreciated! I don't have a spare LCD screen anywhere so that might limit my testing perhaps?
cheers,
batchy
