After dropping my FP3 on the floor something seems to have happened to the screen. It is not cracked, but the screen shows some kind of colorful snow most of the time, see picture below.
Every 10th try it seems to display as normal (i.e. the login screen), but the image is still and does not change. From the vibration motor I can deduct that the system still reacts to touchscreen inputs, but does not update the screen content. The backlight dims and goes on and off as it should when hitting the power button.
Does anyone have experience with this? From my layperson’s understanding I would guess on a partially loose screen cable, but I am not sure whether this is the case. Any pointers are welcome.
