Alright, electrical engineer friends... I'm trying to figure out why my drawing tablet's display broke. I was able to pry it open, and found a cracked diode, but I can't identify it. A bit of searching makes me think it's a tvs diode, but I've no idea what it specifically is (or what an appropriate replacement might be). It looks like it's marked "XM", and I can't identify the logo beneath it (thought it was ST, but that doesn't match their logo)
