Let me begin by saying that this switch is absolutely horrifying. Nothing is in it’s place, and I see a lot of capacitors missing. I’m going tomorrow to pick up some 1uf 10v capacitors and some isopropyl alcohol, then clean this thing until it looks brand new and replace the missing cpu capacitors. I also see a missing capacitor near the 3.3v line (circled), and I’m wondering if I can use one of the ones I’ll have to replace it. Is there anything else I’m missing? I checked with the multimeter and there is no voltage between the 3.3v point mentioned and a ground one. The problem of this switch is it doesn’t boot, literally black screen, so I’m hoping you could help me spot anything else I might be missing. I don’t want to send it to a repair shop and spend 60 bucks just for a easy fix. Thank you.
