Fix and upgrade a ShibaSoku 725D

Hi,


I need to fix and upgrade a ShibaSoku 725D. How can I get a copy of the service manual with schematics. The earlier models have this information available but not for the 725D. Can you please help me obtain the schematic information.

Thank you,
Richard N. Marsh

starstarstarstarstar 		Most common problems of AD725D
by: Henry Dienn

Ni-Cd memory hold battery has leaked and eaten away some pcb tracks and splattered blue electrolyte nearby. The aluminium support bar and side plates have formed a white oxide on them due to the battery leak.
This battery is located on the far right board near the support bar.
Next is bad contact of the boards to their motherboard connectors, especially the boards nearest to the battery. Just squirt some flux remover on the connector pins and seat and reseat a few times. Do this to all boards. Also reseat the flat cables and all other cables with connectors.
Of course any bulging caps and brown burnt areas should be addressed.
I have two of these AD725Ds bought 12 years apart and amazingly made in the same year and month and only 3 numbers between them.
