Hello All— I have acquired a damaged MacBook Pro 15" Retina 2015 that actually appears to be fully functional with the exception of the built-in display. Connecting to an external display works fine, and everything boots and runs as you’d expect. I was told that the machine “got wet”, but the moisture indicators on at least the lower side of the logic board are clear (haven’t pulled board to check the topside). The left side of the case has a slight bend right about where the forwardmost Thunderbolt port is, so I’m wondering if the actual damage was from a fall or if it really did get wet (or both). Anyway, the screen displays a picture, but it oscillates every couple of seconds between the lowermost couple of inches being scrambled and the entire thing being scrambled, w/ multiple iterations of the desktop stacked vertically. Almost like a vertical sync issue. Pictures below. Any suggestions on what to look at? If I can get this operational w/o buying a screen OR at least figure out if the problem lies w/ screen or logic board, that’d be great. Thx, Fred
Sounds like a damaged display. I would replace it. Here’s how: MacBook Pro 15" Retina Display Mid 2015 Display Assembly Replacement Here’s the part, if this doesn’t fix it, you can return the part: MacBook Pro 15" Retina (Mid 2015) Display Assembly
