GENERAL INFORMATION 7.1 DIAGNOSIS 7.1.1 TEST MODE 1. Conditions During Test Mode • During Test mode, the unit will not be shut down for an emergency even if one of the failures mentioned below occurs. • After the unit has been shut down in Normal mode for an emergency upon detection of one of the failures mentioned below, you can turn it on immediately, without waiting for one minute, in Test mode. 2. How to enter Test mode • During Standby mode, hold the AUDIO INPUT and STANDBY/ON keys on the Display unit pressed for 3 seconds. • Test mode can also be entered in either of the following ways: 1. Turn on the power with the STEST port (microcomputer terminal IC5501: 43-pin) at High (5 V). (See "Test mode connecting point".) 2. Turn on the power while holding both the AUDIO INPUT and STANDBY/ON keys on the Display unit pressed. Note: If the power cord was disconnected immediately before, be sure to wait at least one minute before turning on the power in the manner mentioned above. Otherwise, the unit may not operate properly. 3. How to quit Test mode, and conditions for quitting • To quit Test mode, turn the power off to turn the power off. • When Test mode is quit, only data on failure in RAM will be initialized, and data on user settings in RAM will not be initialized. 4. Indications on the FL display when Test mode is entered • The function setting will be DVD/DVR1. • The indication on the FL display when Test mode is entered will differ depending on whether the unit was shut down normally or with an abnormality detected, as shown below: • ADV mode will become 5-channel STEREO so that multichannel output can be obtained. 5. Operations during Test Mode • Basically, operations in Test mode are the same as in Normal mode. However, to indicate that the unit is in Test mode, the following are displayed when the functions are changed: [After a normal power-off] [After a shutdown caused by an EEPROM failure] FL display FL display FL display FL display FL display FL display FL display FL display FL display [After a shutdown caused by high-temperature detection] FL display FL display FL display [After a shutdown caused by over current detection] [Functions] [FL display] • North America • Excepting North America P O W E R O N V O L 0 V 1 D V S E R E E P E R R V O L 0 V 1 D V S E R V O L 0 V 1 D V S E R O V E R P T E M V O L 0 V 1 D V S E R O C E R R R O V 1 S E R DVD/DVR1 I G S E R DIGITAL N A S E R ANALOG T X S E R FM/AM V V V V D V 2 S E R DVD/DVR2 V D D A [Functions] [FL display] V D S E R DVD C S E R PC/GAME U X S E R AUX T X S E R TUNER V V V V D T V S E R DTV V D P A www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com SX-SW77 42 1 2 3 4 1 2 3 4 C D F A B E S TEST U TEST 6.

DSP error display • Each time the SOUND key on the remote control unit is pressed while the power is on, the DSP error display and the normal display are alternately switched. • Power-on time is always counted while the power is on, regardless of unit's functions and operations. However, it is not counted during Standby mode. • The maximum countable power-on time is 255H59M (255 hours 59 minutes.) The indication will not advance beyond that. • The accumulated power-on time basically cannot be cleared. • If "OC ERROR" is not displayed when the unit is turned on in Normal mode, short-circuiting of the speaker terminals can be suspected. • If "OC ERROR" is displayed again when the unit is turned on in Normal mode, the following causes can be suspected: 1. One or more of the ICs among the three digital amplifier ICs (IC3201, IC3301, and IC3401: TAS5122DCA) on the MAIN Assy is in failure. 2. The line between one of the above digital amplifier ICs and the speaker terminals is short-circuited. 3. The XSD line from one of the above digital amplifier ICs to the system-control IC (PDC128A) is short-circuited by grounding or is broken. O V E R P T E M • If "OVERTEMP" is not displayed when the unit is turned on in Normal mode, the unit is normal. (It is likely that this was a temporary temperature rise, lower the volume of the speakers.) • If "OVERTEMP" is displayed again when the unit is turned on in Normal mode, the following causes can be suspected: 1. One or more of the ICs among the three digital amplifier ICs (IC3201, IC3301, and IC3401: TAS5122DCA) on the MAIN Assy is in failure. 2. The OTW line from one of the above digital amplifier ICs to the system-control IC (PDC128A) is short-circuited by grounding or is broken. 1. Breakage or short-circuiting of the communication line to the EEPROM can be suspected. 2. A failure in the EEPROM can be suspected.

Overview Several types of speakers are planned to be used with this product, and according to speaker type, the sound-quality parameters to be sent to the Digital Amplifier section are different. Since the parameters for the planned speaker types have been written in the EEPROM, by simply selecting the speaker type, as shown below, speaker setting is completed. 2. How to select the settings 1. While holding the VOL+ and STANDBY/ON keys on the Display unit pressed, connect the power cord to the wall outlet. Note: If the power cord was disconnected immediately before, be sure to wait at least one minute before turning on the power in this way. Otherwise, the unit may not operate properly. Or, during Standby mode, hold the VOL+ and STANDBY/ON keys pressed for 3 seconds. 2. The power comes on; then the following indication appears. 3. Press the key corresponding to the speaker to be used to determine the setting. The power will automatically be turned off. 3. How to confirm the speaker setting 1. While holding the AUDIO INPUT and STANDBY/ON keys on the Display unit pressed, connect the power cord to the wall outlet. Note: If the power cord was disconnected immediately before, be sure to wait at least one minute before turning on the power in this way. Otherwise, the unit may not operate properly. Or, during Standby mode, hold the AUDIO INPUT and STANDBY/ON keys pressed for 3 seconds. 2. Enter Service/Test mode. 3. Hold the AUDIO INPUT key pressed for 8 seconds. 4. The setting is displayed. 5. If no setting has been written in the EEPROM, "UNKNOWN" is displayed. In this case, the unit will operate in the same way as if "REGULAR 1" (satellite) were set. 4. Error indication When the unit is turned on without any speaker setting, a warning "NO SPTYP" will be displayed. Even with this warning displayed, all key operation is possible. After a key operation, the display will return to this warning indication. R E G U L A R 1 T A L L S P N X T S P R E G U L A R 2 A V G A T E N O S P T Y P S P .

At the output stage, after conversion from PCM to PWM, the signals are output to the Power stage. In this section, timing is controlled so that the MOSFETs on the high and low sides will not be turned on simultaneously. The voltage of the PWM signals are raised to drive the gates of the MOSFET, and the PWM signals to drive the speakers are output from the MOSFET at the output stage. Detection and protection functions against short-circuiting of the output signals and temperature exceeding the standard value are also provided. The carrier elements, high-frequency signals that are unnecessary for these speakers, are eliminated. The signals passed through the LPF will become sine-wave signals, as shown in the figure above. Attention : As a signal to drive the BTL is output from the negative speaker terminal, DO NOT short-circuit between the negative speaker terminal and ground, such as the chassis.

The error indication on the FL display shows the reason a protection circuit was activated. Upon diagnosis of the Digital Amplifier, refer to the specifications for the protection circuits here and the overview of the Digital Amplifier circuitry. 1. Overview The system microcomputer monitors the ports for shutdown requests (Pin 23:SD_AB and Pin 24: SD_CD) and the ports for abnormal-temperature detection (Pin 25: /OTW) of the Power Stage ICs (IC3201, IC3301, and IC3401). As soon as any abnormality is detected, it shuts the unit down. To notify the user of the possibility of a too high a volume, when the unit is turned on the next time, the volume level will be set to 0, and an error message will be displayed on the FL display. 2. Ports on the system microcomputer to be used for detection Pin 77: SHUTDOWN Low voltage at this pin means overcurrent or voltage too low (= V+B27) at a Power Stage IC. Pin 79: XOTW Low voltage at this pin means the temperature at the Power Stage ICs exceeded 125°C. Note: As one Power Stage IC is provided with two channels, three Power Stage ICs (in total 6 channels) are mounted in this unit. For abnormality detection, the unit implements a logical OR operation regarding these three ICs. Therefore, which IC is abnormal cannot be known directly. To find which IC is abnormal, it is required to check whether abnormality detection is activated or not with the abnormality detection port of each IC open (by temporarily removing a series resistor (IC3201:R3201-R3203, IC3301:R3301-R3303, IC3401:R3401-R3403) ). 3. Detection timing Start : Detection starts 500 ms after the PWRCONT 2 port (Pin 84) of the system microcomputer becomes active by your pressing the STANDBY/ON key. Finish : When the STANDBY/ON key is pressed again (when the power-off process starts). 4. Operation of the protection circuits The following three protection circuits are activated when the conditions shown below are met: Overcurrent detection: Indication on the FL display: OC ERROR Conditions: If the SHUTDOWN ports, which are monitored every 10 ms, become low 7 out of 10 times. (If they become low 7 times in succession, the conditions are met at that point.) Abnormal temperature detection 1: Indication on the FL display: OVERTEMP Conditions: If the XOTW ports, which are monitored every 10 ms, become low in succession for one minute. Abnormal temperature detection 2: Indication on the FL display: OVERTEMP (Prerequisite: The XOTW ports, which are monitored every 10 ms, become low three times in succession.) Conditions: The above prerequisite is upheld, and the conditions for an overcurrent detection are met. 5. Process when the protection circuits are activated The unit is shut down within 30 ms after abnormality detection then the volume level is set to 0. The unit can be turned on immediately after the shutdown. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com SX-SW77 47 5 6 7 8 5 6 7 8 C D F A B E 7.1.6 CONDITIONS FOR SWITCHING THE ROTATION SPEED OF THE FAN A fan is provided with this unit. Its rotation speed can be switched between low and high under the following conditions. 1. Conditions for switching the rotation speed from low to high In a case where an audio signal is input and the main volume becomes VOL 20 or more • The rotation speed is not switched to high immediately after the main volume becomes VOL 20 but with a delay of 30 seconds. • If a digital stream signal is not input, the rotation speed is not switched to high even if the main volume becomes VOL 20 or more. • If the function is ANALOG IN, even if there is no audio signal input, 30 seconds after the main volume becomes VOL 20 or more, the rotation speed is switched to high. 2. Conditions for switching the rotation speed from high to low • If the main volume becomes less than VOL 20 • During muting • If a digital stream signal is not input Note: The rotation speed is immediately switched to low when one of the above conditions is met. 3.
