I have an Onyx 550 showing no signs of life (light ring on power plug doesn't even light). Swapping in a known-good logic board confirms that something on the board is the problem. The C1 capacitor rattles when I shake the board, so I'm thinking it has dried out and simply replacing that might fix the problem. Do you know the full specs of the C1 capacitor?
Some specs I can read/see on the cap:
* surface mount design
* Rubycon (manufacturer)
* 220 uF
* 35 V
* 105 degrees C (apparently the top end of the rated operating temperature range)
* NO144 (not sure if that's exactly what it says or what it means)
* 10 mm diameter and 10 mm high
* presumably this is an aluminum electrolytic type
If I have all that right, then it narrows down the selection of caps at [http://www.mouser.com/Passive-Components/Capacitors/Aluminum-Electrolytic-Capacitors/Aluminum-Electrolytic-Capacitors-SMD/_/N-75hqx?P=1z0wrjqZ1z0sq5yZ1z0scm8Z1z0rxa7|Mouser] pretty well.
But there is at the least a question of the low-end temperature rating, and beyond that I would be happy to have someone confirm my overall assessment above.
