Any information on the C17 capacitor for the Apple Cinema Display 23? I accidentally damaged it while desoldering the MOSFET

 

100 nF and likely not critical.

 

Same as C15.
They are in parallel with a 100uF 35V ele cap
Choose a 35V or higher cap. Probably 100nF or 10nF or in that range. If it is on the power supply the value is not critical.

 

Thanks!
