Huawei P20 Lite backlight shuts down after boot

Hi all,

I just replaced my LCD and when I boot up my phone the display seems to work but after 1 or 2 seconds the backlight shuts off. The screen is fully functional; touch works as well as the pixels. I can only see the pixels by holding the screen at a 45 degree angle while shining a flashlight.

Any solutions? Did I connect anything wrong?

I've had a very similar symptom happen on an iPad 2 for example.

I fixed it by cleaning the screen connector on the board with a soft bristle brush and 99% isopropyl alcohol, wasn't making a full connection so backlight would shut off because it couldn't get full power.

That doesn't seem to work. Also I forgot to mention that the backlight of the broken screen is working when I try that one.
