iPhone X Dropped my phone and now it has a cyan bar through it

[Mark200789]

Knocked over my X this week (in a case) and when I turned it on there was a thick, super bright, cyan bar running through it. I did some reading and some folks with a similar issue said it could be a poorly attached cable. I took the phone apart and undid and redid their cables. The problem remained. Now I don’t know what the fault is and what to replace. Is it the screen? Is the the logic/graphics board? Running screen mirroring on my Apple TV doesn’t show the error. But maybe the mirror output is a different chip than the screen output? I don’t want to spend too much on fixing this, but also don’t want to buy a new phone until September. I mean, we’re nearly there, right?

Let a shop take a look at it. It's rare that a display connector becomes loose after a drop. In many cases, solder joints are outright broken. It's not something that can be repaired without skills, knowledge, and tools.

I have all of the above. There’s nothing in this device I wouldn’t be able to replace.

these phones are not as sturdy as macbooks, but taking apart the phone is good on your part.
which you know is a hardware-logic board issue.
you could use an app to forward calls to a laptop until the new ones are released in early September.

Buy a used old iPhone and use it until the new phone 13 comes out, then buy the 13 and sell the old one. Or better yet keep the old one too- because everyone should have a functional backup iPhone anyway

Grab a third party screen to test. It looks like screen especially when the display outputs to another screen.

I wouldn’t know 100% though sorry.

I'd say it's the screen. I've had similar on regular monitors.

Display is FUBARed... replacing the display should fix it as long as there isn't damage to the logic board as JPack stated...

OP could you tell us what case is on your phone? So we can avoid it lol
