This novice soldering iron operator needs some more help. I've attached my BW screen to the Pi Zero and get no response upon powering on the Pi. I've already tested to make sure the Pi itself is still working via HDMI. One thing I regret not testing was whether the screen would work prior to disassembly. Is there something I need to set up on the Pi itself before it will recognize the screen? Looking at the images below, can anybody identify possible culprits for the failure?
I've tried both white and yellow wires to no avail. I've also clicked the buttons on the screen, also with no result. Also, I noticed that piece of white fluffy stuff on the BW board. It was a piece of dust that must have fallen off and is not attached to the board itself.
Any ideas I should try before I throw in the towel and spring for a GearBest screen? Thanks for the help.
