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.
