Date: 25/09/98                       Revision No: 01                    Document No: 01
Subject: Grinding Sound from Capstan Motor


SYMPTOM:                 Crunching/grinding sound coming from the capstan motor, as if bearings
                         faulty. Replacing capstan motor has no effect.


CAUSE:                   Ripple on the 5V rail, from the power supply. This 5V's goes to the
                         capstan drive IC, IC2101, causing the drive to the capstan motor
                         to be incorrect.


REMEDY:                  Replace C1122 (Part Number ECEA1AFZ331X) 10V 330uF cap,
                         and possible dry joints on plug P2001.
