This set is a component of the MHC-S9D. The MHC-S9D system configuration is as shown belo w , and there­fore it does not operate normally unless all four components are connected. In performing the repair, connect all components with the system cables. Note: The precaution to the users is described on the label stuck on the back panel (DVD/video CD/CD player) and in the trouble­shooting section in the Operation Manual.

Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUB­LISHED BY SONY.

TEST MODE

ST-S9
Note: Use following buttons in the test mode.
no mark: Button of tuner unit (ST-S9)
1
*
: Button of amplifier unit (TA-S9D)
2
*
: Button of DVD/video CD/CD unit (DVP-S9)
[MC Cold Reset]
• The cold reset clears all data including preset data stored in the RAM to initial conditions. Execute this mode when returning the set to the customer.
Procedure 1:
1. Press the ?/1 *1 button to turn the power ON.
2. While pressing the [DIGITAL]*1 button, press the
[DISPLAY] button.
3. The set is reset, and becomes standby state.
Procedure 2:
1. Press the ?/1 *1 button to turn the power ON.
2. While pressing the both [PLAY MODE]*2 and x *2 buttons,
press the M *2 button.
3. The set is reset, and becomes standby state.
[MC Hot Reset]
• This mode resets the set with the preset data kept stored in the memory. The hot reset mode functions same as if the power cord is plugged in and out.
Procedure:
1. Press the ?/1 *1 button to turn the power ON.
2. While pressing the both [STEREO/MONO] and [CINEMA
STUDIO C]*
3. The set is reset, and becomes standby state.
[Change-over the AM Tuning Interval] (EXCEPT AEP, UK and Sauidi Arabia models)
• The AM tuning interval can be changed over 9 kHz or 10 kHz.
Procedure:
1. Press the ?/1 *1 button to turn the power ON.
2. Turn the [FUNCTION] *
the [TUNER/BAND] button to select the BAND “AM”.
3. Press the ?/1 *1 button to turn the power OFF.
4. While pressing the [ENTER] button, press the ?/1 *1 button,
and the display on the fluorescent indicator tube changes to “AM 9 K STEP” or “AM 10 K STEP”, and thus the tuning interval is changed over.
[Change-over of VACS ON/OFF]
1. Press the ?/1 *1 button to turn the power ON.
2. While pressing the both [STEREO/MONO] and [CINEMA
STUDIO C]*
and VACS ON/OFF is change over.

buttons, press the [CINEMA STUDIO B] button,
[GC Test Mode] Enter the GC Test Mode
Procedure 1:
1. Press the ?/1 *1 button to turn the power ON.
2. While pressing the both [STEREO/MONO] and [CINEMA
STUDIO C]*
1
buttons, press the [CLOCK/TIMER] button.
3. LEDs and fluorescent indicator tube are all turned on of all units.
Procedure 2:
1. Press the ?/1 *1 button to turn the power ON.
2. While pressing the both [PLAY MODE]*2 and x *2 buttons, press the Z (DISC 1)*2 button.
3. LEDs and fluorescent indicator tube are all turned on of all units.
Version Display Mode
Procedure:
1. Enter the GC test mode.
2. Each time the [TUNER MEMORY] or [DISC 1]*2 button is pressed, microcomputer or mechanism deck version is displayed of each unit.
3. Press the [TUNING +] or [DISC 3]*2 button to detail is displayed the version.
Key Check Mode
Procedure:
1. Enter the GC test mode.
2. Press the [TUNING -- ] or [DISC 2]*2 button to set the key check mode.
3. In the key check the mode, the fluorescent indicator tube displays “K 0 J 0 V 0” . Each time a button is pressed, “K” value increases. However, once a button is pressed, it is no longer taken into account.
VACS Level Display Mode
Procedure:
1. Enter the GC test mode.
2. Press the
[TUNING +] or [DISC 3]*
2
button to display VACS
level on the fluorescent indicator tube.
Segment Check Mode
Procedure:
1. Enter the GC test mode.
2. Press the [ENTER] or x *2 button to set the segment check mode.
3. In the segment check the mode. Each [ENTER] or x * button is pressed, the fluorescent indicator tube displays is switching variously.
2
Releasing the GC Test Mode
