I have an HP Chromebook x2 11 that was working great, but the display backlighting just stopped working and you can barely see anything. I had to figure out it was working by using an external monitor.
I was able to disassemble it, but I'm not confident of buying a replacement online, which would already cost like $70. It's not clear to me if this is a display with glass that only needs connecting the two ribbon cables, or there is more work: https://www.amazon.com/GBOLE-Replacement-Chromebook-11-da0000-Digitizer/dp/B0DLBG1X23
