that one diagram is all I have been able to find for the Sega Genesis MK1 and I'm not even sure it is the correct board revision.
For some reason I can find plenty of Service manuals for the Sega Genesis MKII though
What are the primary specifications needed for choosing a new Capacitor, Capacitance and voltage?
The capacitor I'm looking at replacing:
It is
surface mount.
It is
ceramic.
I don't think it is
polarized.
Voltage rating? As long as i'm equal to or higher than the original I'm ok ?
Capacitance ? There is probably no way to measure the capacitance since the part is damaged.
I'm not sure what changing the capacitance rating does, too low and It can't store enough energy? Too high and it ____ ?
I found this list of all the electrolytic(only) capacitors in the Genesis Mark 1 VA3, not really helpful since it doesn't list the ceramic capacitors though.
Label
Voltage Rating (V)
Capacitance (uF)
