So far, I successfully fixed 3 or 4 screens with one or more vertical lines missing, and it is always corroded pcb traces or pads, only one screen was unfixable, and I'm almost certain it is trace on the glass that somehow got damaged, swapping the strips didn't bring line back :( In one case pad was just gone, totally corroded, I cleaned zebra strip with some isopropyl alcohol and used thin copper wire in place of pad and it worked! https://twitter.com/S0N1Czzz/status/1121517768657055744
