Subject: Common Faults

                         CHANNEL LOCK UP PROBLEM

SYMPTOM:                 The position on the Front Information Panel (FIP) can be changed or locked
                         but the tuner picture is always the same when the customer changes the
                         channel on the VCR. Also, there is no OSD.

CAUSE:                   The channel data transmission between IC7706 and IC7704 (serial clock
                         & serial data) is corrupted (permanently keeping the signal HIGH), but
                         data transmission of the OSD microprocessor and system microprocessor
                         are correct (for FIP display). Therefore, the result being that the FIP
                         display works properly but the tuner data does not, resulting in an error.

REMEDY:                  Please add the oscillation circuit to prevent the noise effect on IC7708.

Date: 25/09/98                     Revision No: 01                    Document No: 01
Subject: No Sound Using PDC & Non-UK OSD Standard

                       NO SOUND USING PDC (See models above)

SYMPTOM:               No audio on Programmed Delivery Control (PDC) recordings.

CAUSE:                 Due to tolerance of channel carrier frequency (+/- 200KHz) audio mute
                       may occur particularly on cable systems.

REMEDY:                Where no sound is recorded using PDC we advise that re-tuning is carried
                       out as follows to store new value for channel offset frequency:-

                       1)     Switch the VTR ON.
                       2)     Switch the machine into shipping condition following the procedures
                              laid out in the appropriate instruction manual. (This should result
                              in memory erasure).
                       3)     Switch the machine OFF at the mains.
                       4)     Turning the VTR back ON will initiate the Auto Setup Procedure.

                       If problem persists, please contact Technical Support on 01344-853501.

                       NON UK OSD STANDARD (SD400/HD600 Only)

SYMPTOM:               Incorrect OSD data code, resulting in wrong video plus codes and auto time
                       setting not working.

CAUSE:                 There is a possibility of the data from IC7704 (EEPROM) getting corrupted
                       by disturbances on the serial data line between IC7706 (OSD uProcessor),
                       IC7704 (EEPROM) and IC7708 (TEXT IC). This can be due to switching
                       of power supply or by static current (thunder).

REMEDY:                Change the supply voltage (VDD) of IC7708 (Pins 1, 10) to non-switch 5V
                       from Reg. 5V.

                       1.     Remove L7704.
                       2.     Add a jumper wire between Pin 28 IC7701 and positive side of C7714.

                       Reset the OSD data following the procedure in the appropriate service
                       manual (Page 1-1).
