TAB error or other display/connection problem?
I was trying to find answers for colored vertical lines that pop in and out of the display and eventually came across answers on iFixit that seems to indicate my issue is TAB related. I just wanted more information about TAB errors since I wanted to confirm that it’s the same issue that I’m currently experiencing!
The display randomly seems to return to normal when the laptop is on a flat surface and when the lid is not in motion. Is this indicative of TAB errors? Like some other posters have mentioned, pressure on the display does seem to multiply these lines, however after letting the display rest for a while it seems to go back to normal (no visible lines).
The lines seem to always pop up on the login screen but seem to disappear on the desktop page (which has the same image as the login). I’ve tried performing the hardware diagnostics and nvram reset but nothing seems to pop up as odd.
Lastly, is it likely that Apple would be able to replace the display since it’s still under warranty and there were no incidents involving falls/drops/pressure/water with the device?
Pics added in edit, screen is a little dirty but I think it’ll be clear to see.
Normal (No lines are visible whatsoever):
When pressure is applied via finger:
The screen returns to normal when on a flat surface and gets 3-5 lines when in motion at a specific small area.
