I just completed iFixit’s Google Pixel 3 Battery Replacement guide. Upon powering my phone back on, I was greeted by the sight of beautiful green vertical lines.
I was wondering where I might have messed up; do any of the steps shown in the aforementionned guide present a risk to the display if done by a poorly skilled technician such as myself? I ended up using some 99% isopropyl alcohol to loosen the pull tabs on the old battery. Could an excess of that be responsible for my current problem? Update (03/30/2022) The problem “evaporated” on it’s own. I guess it was the alcohol, after all…
FYI, I had the same thing happen, though my lines were on the left side of the screen. I too used isopropyl alcohol to get the battery out. My lines also disappeared - only took a few hours.
