ONLY the backlight is working before AND after Display replacement
I have a problem.
My Iphone 8 had a broken screen and the display no longer showed anything. Only when you turn it on in a dark room you see a glow, from which I conclude that the backlight still works. After I replaced the display, the same error still occurs. Can this be due to the logicboard? It was not my first repair, I already have some experience. Or are there any computer programs with which one can go on troubleshooting?
Thanks for all answers
