so reseating behind the screen? I only tried reseating the cable on the mainboard
I suspect bad electronics. There is a control circuit board underneath the screen any pressure on this or the screen can cause this issue, these are incredibly delicate screens, I know from personal experience. They used to make screens with a metal surround frame to prevent flexing and such like, not any more.
Forgot to say, I’m selling a brand new screen for £100 if you need one.
Might as well try it while you’re waiting on the mainboard replacement, especially if you think you might have disturbed any other part of the cable
Reseating on the screen side did nothing unfortunately same issue
So I replaced by the new mainboard (with the 2 sticks of RAM), works but the screen remains as broken
I just looked into your ticket, support has indicated the issue is the display. All you need to do is reply to their message and support has a resolution for you.
