Dear All,
this is my first post here, I've recently found a Revolution X (3 players version) that won't boot.
I've re sold some chips that was not showing in optimal conditions, replaced all the electrolytic SMD Caps, cleaned the board , fixed 2 damaged tracks close to C22 and C17 but game it's still not booting.
+5V Led is solid On
Status Led it's randomly blinking
All the 3 Clocks are present (40 - 8 and 25MHz)
Now, since I have the cab far from mine lab , let me ask you, can I just test the board without having the cab with me?
Can I just test the main board without connecting audio board and gun board?
what should i connect? just +5V, -5V, +12V and video out cable to a monitor for testing?
From where I should start from?
Reset signal High and stable ... then? Video Chip? GAL? Rom? Ram?
Thanks to everybody would like to help me
