Hello, first time Xbox repair-er here. So I took an old Xbox out of storage (10-ish years). Turned it on and it powered up fine, clock set screen came up which was expected since I assumed I was going to be ripping the clock cap out anyway. Also the disk tray wouldn't open, again an easy fix, no big deal. I open it up, clean the DVD drive and reset the belt (boiling water, etc.) and put it all back together. Only this time it doesn't turn on. I can hear a faint noise coming from the hard drive but nothing else, no indicator lights, no disk tray activity, nothing. My guess is more than one of the caps was going bad and that final power on I did was just the nail in the coffin. I plan to open it up and do a full cleaning to see if there's anything obvious, but the fact that the HDD seems to still be getting power makes me think that I possibly broke something. Is it possible that bad caps could cause power to stop going to certain components but not others?
