Have a Sony Model SVO-9500MD Videocassette Recorder in our shop for
repair.
Customer Complaint: Video jitters up and down.
Have seen intermittent Error codes 20 and 90, but don't know what they
are, as we do
not have an owner's manual or service bulletin on this unit.
Can anyone advise what these error codes represents?
Your help would be greatly appreciated.
Thanks,
Jim
