So, hello! I’m not sure wether you can help me, as I am really out of my depths. I am really despaired right now.
As the title says, my screen stays black, the other, old one works. The other one is extrememly broken, full of splitters and even has a hole below the touchscreen, so I had no choice but to get a new one, if only in case that the old one fails. My phone is out of warranty. One thing though, the that phone isnt a nokia, the screen doesnt stay intact, but it really seems impossible for me to kill this thing in normal use. And I have dropped it more times than I could possibly count.
So well, I’ve spend all day with this shit, wiping my phone and installing switchers because I wasnt sure what exactly that update according to this guide was for, the OS or the Fairphone OpenOS. Then I flashed back to OpenOS to test a users claim that TWRP has special access to the screen and if it works with TWRP then its software related. Well, it stayed black. Cleaned contacts, reassambled and rebooted the phone multiple times. Updated again, just to be sure the failure wasnt just a fluke.
I’ve also checked for any kind of foils sticking out from the new screen that might be blocking connection, but I have found none. If you know of some, please point them out, that’s one of my hopes.
While comparing the old and the new screen’s backside I have noticed two differences in the following picture featuring the old screen on the left and the new one on the right.
First, the big metal plates at the bottom are different.
The right one is rectangle for the new one and a slightly smaller square for the old one. Then the metal plte
The left one is a rectangle for the new one and a clearly different and bigger shape for the old one.
Next, the contacts (stripes with profile) on the bottom.
The new display has one such contact on the left and it is noticably bigger than the stripe on the old display’s left.
The new display has two contacts on the right, but one is bigger than the other, unlike on the old screen.
I’ve also first regarded a third stripe on the left to be the same as the other two, but it doesnt have depth (profile) it seems it has just been printed on the plastic. It’s not my first supect, but since it’s a clearly noticable difference about something I don’t understand, I thought, it is worth to register it.
The rest of the backside is the same, I’ve used a lineal to compare the distances between contacts and I have counted the number of squares on this elongated group of contacts. They are the same.
I’d appreciate if you can help me to get this to work, preferably without having to send it back.
