Vintage Synth Explorer Forums

Hi all, I replaced the two EPROMS in my Korg Prophecy and the unit is now just showing the KORG Solo Synthesizer startup screen, but no further. No red lights except for the Speed indicator which lights up, holds for five seconds, then flashes at a continuous speed.

Please help with any advice?

Maybe I disrupted a keyboard connection when opening the device.

I'm experiencing the EXACT same problem, did you ever resolve the issue?
