C20 and U21 Identification

I’m trying to fix an xbox one x with no display. I’ve replaced the retimer chip, but in the process I lost the C20 capacitor. Is anyone able to identify the capacitor so I could order a new one?

I’m also pretty sure that the issue is actually the U21 chip. I’ve been unable to locate anywhere to get this chip. It says ST G NFD 738. Does anyone know where I could get this, or am I stuck hunting down a donor board?

Were you able to identify the C20 capacitor?

Thanks

I’m in need of a U21 chip as well but I don’t think they are available for purchase. From what I found so far you need to get it off a donor board.
