I took the laptop to a tech service that specializes in laptop screen
replacements. They diagnosed the problem as a malfunctioning LCD
screen cable (part # 447986-001). Apparently the original tech damaged
it during his service. The specialists are charging me $120 labor, and
the used part costs about $50+ on eBay.
Turns out it would have been cheaper to let the more expensive
specialists fix the screen in the first place.
