Screen of iPhone SE shows only vertical and some horizontal lines
I replaced the battery in an iPhone SE - Model A1723 - Model name MP822DN/A.
After the repair action the screen shows only equidistant vertical and some horizontal lines.
I attach a picture of the situation.
The iPhone cannot be used any more.
I thought that some cables to the screen became loose.
So I opened it again and made sure that all cables are fix.
Unfortunately, the result was the same.
When I opened the iPhone SE the first time the momentum while pulling off the front screen was pretty high. Therefore the cable for the home button became loose.
Could it be that also a cable for the screen became damaged (during the opening process)?
I haven't seen this behaviour of an iPhone (and a screen) before.
Do you have any idea what is the reason for this behaviour?
Any feedback would be gladly appreciated!
