PSA: That weird flicker on a 2018 MacBook Air took me a full day to track down
It was a simple screen flicker that only happened when the lid was at a certain angle. I replaced the entire display assembly first, which was a big waste of time and money. After that, I spent hours checking the board for cracked solder joints under my microscope. The real fix? A single, tiny piece of conductive foam that had come loose from the lid and was shorting the LVDS cable connector when the hinge moved. I spent 8 hours on what should have been a 30 minute cable reseat. Has anyone else had a 'simple' flicker turn into a major hunt for a stray part?

Check for stray foam first, like @lily_black44's bent pin.

Spent a whole weekend convinced my old Thinkpad's GPU was dying from graphical glitches. Turns out I had just slightly bent one pin on the RAM connector when I upgraded it. Felt like a total genius after all that stress.

That piece of conductive foam is a classic. Always check for loose debris in the hinge area before you go deep. It's saved me from a few pointless board repairs.
