Subject: [disklavier] Mark IV Service manual
 
  
Apologies if this message appears a second time not sure if the first one got through it was my first to the group. Forgot the subject line.
 
Can anyone help me out with access to download a Mark IV service manual.
 
My recently acquired used Mark IV has failed within a month and has various sequences of flashing lights. 
 
The manual will help me understand the problem before calling out a tech if needed. 
 
Basic things like hard drive or board replacement I can do myself, beyond that I will call in a Tech.
 
My main aim is to work out what has failed.
 
I am in Melbourne Australia
 
Thanks in advance for your thoughts.
 
Darren
