Black screen after install on fresh C2

See original GitHub issue

Describe the bug

My comma two stopped working a couple weeks ago - it will power on but once it goes past the Comma logo startup the screen turns black (with the backlight still on). I was able to get into fastboot and do a factory reset via eon-neos, but once it finished installing openpilot it returned to a black screen. Same results with installing dashcam.

Install logs:

Just read thru this thread. Received my brand new C2 on Saturday. Same exact issue. Starts up, gets to the Comma logo startup screen, then goes black with the screen backlight still on. this occurs both plugged into the vehicle using the supplied harness and plugged into my Mac. I’ve tried powering off and back on and rebooting. Figured another example of same issue might be helpful.

I am having the exact same issue. ~1 y/o comma two with identical blank screen behavior after openpilot installation. I noticed that I have a similar line in my installation log to you as well. Mine is:
