Service manual for SHIMADZU model: EB-3200H

[sree1974]

Hello,
I'm working on a SHIMADZU electronic weighing balance model EB-3200H. The display cannot be zeroed and sometimes the unit doesn't even enter measurement mode. Tried contacting the manufacturer but no luck since the model is now obsolete.Would be appreciative if someone could provide the service manual and/or give me some repair tips.

Thanks in advance.
