Why does my screen stay black but touchscreen works? (Pro 6)
1) I have an issue with my Surface 6 Pro, which I bought used with a broken display. I replaced the screen. When I turn it on, the backlight makes the screen bright for a few seconds, then it stays dark. When I connect the device to an external monitor, everything is shown there. I can even use the touchscreen of the device. Nevertheless, there is displayed nothing on itself. Which is weird, because the screen turns bright short, so there is a working connection somehow (I even tested 2 flex cables).
2) The weird thing is, I tested the same thing with the same screen on a Surface Pro 5 LTE Advanced. Same thing there, except, one time, the Surface Logo was shown. Otherwise, same problem. In addition to that, I replaced the battery on the second device. A small LED right above the battery turns on when I connect the charger. The device boots like the Pro 6 (nothing on screen except the short brightness after pressing the power button). But it also turns off immediatly when i remove the charger. When I first inserted the new battery, the LED also turned on just from the contact between mainboard and battery. This is not the case anymore and I dont know why.
Under windows, the battery charges regulary. Charger removed - device dead instantly. Cant turn on without battery.
Added: With the Pro 5, the LED also lights up when I completely remove the battery and connect the device to the charger.
