Chosen Solution
I upgraded the RAM using tools and adhesive strips from this site. A few days later, the display separated from the chassis and torn some wires away from the display connector in the process. I have a few questions: What did I likely do wrong when I replaced the display? The strips are still attached to the chassis. Was I supposed to heat or significantly pressurize the display?Can the ribbon cable be repaired or replaced in the display?Where can I order a new display if that’s what I need? Thanks! John

At this point you’ll need a new display assembly, hopefully you hadn’t damaged the logic board connector.
