Check your cdrom ribbon cable. It’s probably backwards.
I happened to have a newer build of Saturn laying around and I tried installing the MODE board in it minus the external power wire included and recommend for use on the original Saturn I installed the MODE into that wasn't working. The MODE at least is coming on, I haven't loaded any ROMS on it as of yet. I reconnected the mode into the first Saturn minus the external power wire and turned the switch off. So far it seems to be working so either the installation instructions need to be updated as to when the extra power wire is needed or maybe a firmware update remedies any issues that may occur.
