Why won't touch work on my iPhone 11?

I had to change the bluetooth antenna of my iPhone 11. Everything went smoothly, and when I plugged in my screen, for a moment everything seemed to work perfectly. After about 30 seconds, I noticed some ghost touches on the iPhone screen. I figured that the connector might be a little loose or something, so I shut off the iPhone, checked the connections and turned it back on again. Now I saw no ghost touches, but rather the upper part of the screen didn't work at all. I repeated the previous step, and everything got worse: 2/3 of the screen stopped working, from the top to the bottom. I happened to have a screen replacement, and tried that: same result. Now I get no screen feedback - the screen works, is bright and all, but I can't press anything, unlock my phone etc. What might be the problem?

Hi!

Did you make sure to disconnect the battery?

If you left it connected you might have fried some of the display circuits on the logicboard

Also have you tried cleaning the connector with isopropyl alcohol?

Doing this can help clear dirt out human eyes cannot see

Thanks:-)

Thanks for your answer! I ordered some isopropyl alcohol and cleaned the connectors - they are for sure clean now. But it still doesn't work... :(

I'm also absolutely 100% sure that I disconnected the battery each time: it's the first and last thing I do each time I work on a phone.

Could the display circuits nonetheless be fried? Can you think of any other possibilities?

@hellomacos less likely on an 11 as its oled

@tech_ni

True…but I though the 11 was a lcd because it was meant to be a cheeper phone

Il need to look it up but your probably right XD

What do you guys mean? That the lcd-screen makes it more improbable that the circuits are fried? Or that it's less likely that there's dirt in between?

Did you replace the LCD/OLED and screen or just the screen? It sounds like the LCD/OLED is damaged or it could be something was put back together wrong causing increased pressure on the LCD/OLED.

I replaced entire the LCD-apparatus, with one that I am sure is working on another phone. That is why it feels incredibly odd that it stopped working, all of the sudden.

Then its probably connections to the lcd on the MB
