Internal display problems after repair
After I replaced a faulty right speaker in my MacBook Pro 15" Mid-2014, the internal display went awry. The screen is distorted, visually squeezed to the left-third, is fuzzy like static in an old TV.
External displays work. Both HDMI and DisplayPort. All other functions, like airport, keyboard backlight, FaceTime video, and all work.
What I tried:
- I've reset PRam, SMC. Tried safe mode and recovery.
- Cleaned any dust/dirt away from connectors with dry, soft toothbrush
One of the steps says be very careful not to touch the cable connector after removing it. Could it be that I did, and this is the result? I've tried reseating it several times and I see no change. Do I need to clean it, with what?
Login page. Internal display glitched. Functioning external display (in mirror mode) above laptop.
The display connector looks clean. What's a cheap/easy way to clean it more?
Is this a good question?
