Same here! I also findout that lcd still works, if you get some flashlight on screen in a dark room, you will see that only backlight not working when battery plugged. I tried to baking it but it still didn’t worked. It’s obvious that backlight could properly operate as it works when you take off the battery. I’m looking for solutions, if I find any, will wrote it here.

Did someone find a solution to this? I also replaced my screen and it keeps black solid when I turn it on, even with the touch working properly.
