MacBook Air 13" Retina Late 2020 LCD issues after startup

My Macbook air m1 a2337 is having LCD issues. On startup & login, the LCD is fine.

Then when i click on an application, that's when the screen quality turns into this:

I have the IFIXIT Pro Tech Toolkit. Im just looking for someone to identify which part inside is the issue? Apparently it's one of the connectors. Also if you can identify the part, where will it be located & a picture example. If there's a video that's even better. This is the only issue. The macbook runs fine.

Your going to hate me☹️

Your issue is not a cable, this is likely a T-CON board failure which is part of the display assembly. Basically the scan rate of the display changes when jumping from the OS to when you launch the App. The T-CON sets the scan rate but when the clocking is messed up you can encounter this effect as the screen is not being driven correctly.

To prove this plug in an external display, if it reacts correctly and the internal is still messed up, thats the problem. Now if the internal starts working correctly when the external is connected then the logic boards video driver logic is messed up.

@danj I decided that i'm going to purchase a new display. Either the T-CON or video driver will cost to get replaced, so may as well just buy a replacement display. Thank you.
