Make sure you didnt replace non polarized caps with polarized ones.
I believe that all the capacitors in the audio section of a MV1-FZS are polarized.

Bummed. I can't create threads because I'm new.
I recently picked up a MVS system. I am
Not getting any sound or picture from the monitor. I've replaced the power supply but that did not work. Do you guys think a cap kit would solve the issue?
First... ALWAYS reset the backup RAM in the hardware test menu and power cycle the board if you have zero sound.
If that's not it then probe the YM2610's digital inputs with a logic probe that has audio capabilities. You WILL hear the digital information on the clocked pulses going into that 2610. If it's there then the digital part of the circuit is working. If it's not then you have a problem in the digital section.
When I get home from Japan this week I'll record a video and throw it up on YouTube to show you what I mean about checking the inputs to the YM2610 with a logic probe that has audio capabilities.

Is your issue resolved yet?
Problem solved by replacing the Z80 on the board.
