Roland W-30 no startup

Hi,
My Roland W30 startups but doesn’t ask for the OS disk. The display keeps showing “Roland W-30” and that’s it. Any ideas ?

Ive disconnected the drive data cable and power to isolate any potential issues but no luck. I can do in depth troubleshooting if needed

Thanks

Any help will be appreciated

Usually this problem is related to a defective floppy disk drive. Also, If the floppy disk drive is removed, the same thing will occur and the sampler freezes at the “Roland W-30” screen. There’s some useful info about replacements at this link --> http://llamamusic.com/s50s550/fdd_tech.html
