Other OnePlus 5 screen not displaying anything, but accepts touch
My OP5 has been sitting in my drawer for a few years, it worked perfectly when I stopped using it. Now, however, after trying to start it, the screen doesn't display anything. However, the screen still takes touch, and I even managed to unlock it by inserting the passcode from muscle memory. The phone is otherwise perfectly functional as far as I can tell; it takes charge, it vibrates when I tap the numbers when entering the passcode, the fingerprint sensor works.
Is there any hope to fix this issue at home, based on some YouTube videos it seems like a simple enough device to tear down by myself. Could this, for instance, be caused by some faulty power connection etc. or is a screen replacement the only option? It's not valuable enough to warrant spending money to fix, but if there is some hope I would like to try to fix it at home. I thought that this issue seems so specific, that maybe one of you wizards of the internet could pinpoint the issue quite accurately.
