No Image and no iTunes connection

So this iPhone 7 has no image and does not connect to iTunes.

After opening it i figured that it was little bit low on battery, after charging the phone, the battery was on 3.8V which should be fine.

After hooking it on a DCPS, the ammeter didnt show any suspicous behaviour.

No current without booting.

Around 200 - 400 mA current on booting with one spike to 1 - 2 A. I think this is fine right?

Additionally, I checked all the display connector pins on the logic board in diode mode and they are normal.

However I have no idea what I could check next. Any ideas?

At first I was thinking it might be that the display is the problem, but since it doesn't show up in iTunes as well, I think it might be a bigger problem.

The readings from your DCPS are that of a phone that is booting. If it has a passcode iTunes will not recognise it till it has been entered. Your next step is to determine if it is an image problem or backlight.

·         Check for image with a torch on the screen.

·         Check all pins on the LCD connecter and make sure none are pushed into the plastic.

You're right with iTunes.

The pins are fine, and i also could see no image with a flashlight, so it seems backlight might not be the problem.
