I have a serious problem with my Tyros - If anyone can help or suggest anything I would be very grateful.

When I power on the keyboard I get the following message almost immediately at the top of the initial Yamaha screen:

"Improper Shutdown! Backup data and/or uerfiles have been lost"

The screen then clears and a plain blue background appears with the following text:

Unexpected error
Turn off the Power and on again
................................
hisysdwn.c/133/8C258926

Obviously I have tried to power up again and again but always get the same mesage.

I re-loaded the operating system (all 14 disks) which completed succesfully but at the end I still got the same error message.

I also ran the diagnostics (by holding down the Direct Access button when switching on)which after going through all the checks gave the following results

Main Boot
Sub Boot
Main Prog.........1.4 OK
Sub Prog..........1.0 OK
Bmp...............1.0 OK
Style.............1.0 OK
Voice Parameter...1.0 OK
Preset............1.0 OK
Font..............1.0 OK
Wnn...............1.0 OK
Wave..............1.0 OK

The error message first appeared as I was starting the Tyros up in Bulk USB mode. I was wondering if I momentarily lifted my finger ifrom the Music Finder button while the system was starting. If any of you guys use this mode for fast file transfer then I advise you to take care.

Thank goodness I still have my Ketron XD3 which I can use with my old dad's Technics 6500 as a keyboard controller for my gigs.

I will call Yamaha tommorow and the local engineer but I just know it's gonna take a while to fix this.

Aaaaaaaaaaaarrrrrrrrrrgggggggggggghhhhhhhhh
