PIONEER VSX-1022-K - VSX-42 -VSX-822-K 

SERVICE MODE SOFTWARE UPDATE IDLE CURRENT SETTING AND POWER AMP CIRCUIT 

SERVICE MODE
Purpose
The numbers of detections for various protection processes are displayed.
How to enter/exit
During Standby mode, simultaneously press and hold the [PRESET LEFT ] and [STANDBY/ON] keys for 2 seconds to enter this mode.
The display will return to the normal indication when no key operation is performed for 5 seconds.
Reset mode for numbers of protection detections
Purpose
For clearing all the counts of protection detections.
(This mode resets the counts of protection detections.)
How to enter/exit
During Standby mode, simultaneously press and hold the [ALC/STANDARD SURR] and [STANDBY/ON] keys for 10 seconds to enter this mode.
The display will return to the normal indication when no key operation is performed for 5 seconds.
Detailed explanations
1. When the procedures for Reset mode for numbers of protection detections are completed, all the counters will be reset to "000."
2. Prohibitions:
The protection detection counts cannot be cleared (reset to 000) with the MEMORY CLEAR process. They can only be cleared when the procedures of Reset mode are completed.
Notes on Ground Points Connection
During repair, before checking the MAIN Assy, etc., with the rear chassis removed, be sure to connect the GND terminal of the main capacitor to the back chassis (speaker chassis), as shown below, then connect the power cord.
Without grounding connection, the protection circuit will be activated. After repairing, be sure to remove the ground wire before reassembling.

SUB microcomputer firmware update
Preparations
Save the firmware file to the "root" of empty USB memory.
The file name of the firmware file is "RegM13Sub_V***.bcd". Don't save other files.
# NetworkStandby: OFF
# HDMI Control: OFF
# HDMI StandbyThrough: OFF (North America model only)
# Connect a unit to TV and HDMI, and the GUI output of the unit performs in a state to appear.
Procedures
1. Turn on the unit.
2. Set a function for a "NETRADIO".
Note:
Without a network connection, "Server Error" will be displayed on the TV screen. Under this condition, the Service Menu (menu for updating the SUB microcomputer) is not accessible. Set the remote control unit supplied with the unit to Network Function Operation mode then press the ENTER button so that "Empty" is displayed on the screen. Then proceed to Step 3.
(2) When a product cannot recognize a file, FILE NOT FOUND. Check on USB memory with a file.
3. Press the "ESC (A85F)" button on the Service remote control unit (GGF1381), then press the "+10 (A81F)" button to enter the service menu (for SUB microcomputer firmware update menu).
When you press other buttons between "ESC" button and "+10" buttons, be invalid.
4. Press the "ENTER" button of the remote control unit supplied with Network Function as the state that you can operate.
(1) When a product can recognize a file, become the following indication.
Select "Start", and press the "ENTER" button.
5. Update starts, and "UPDATE" blinks to FL screen and HDMI LED blinks. Be approximately 8 minutes for update at time.
6. When update is completed, "Completed" is displayed by TV screen and HDMI LED lights.
* "UPDATE" blinks to FL display and is displayed.
In rare cases, "Completed!" may not be displayed on th TV screen. In such a case, updating is completed if the HDMI LED has become lit. Proceed to Step 7.
7. Disconect the AC power cord. (The POWER button does not respond.) Confirm a version of the firm ware of SUB microcomputer.
Note:
Because update is not possible again, never unplug the power cord until the updating process is completed.
USB (BridgeCo) firmware update
Procedures
1. Select ‘Firmware Update’ from the Network Setup menu. The receiver checks whether the USB memory device inserted into the USB port on the receiver’s front panel contains updatable software.
2. To update, select ‘Start’.
3. When ‘Updating in progress, don’t unplug!’ is displayed, select ‘OK’.
# If ‘File Not Found’ is displayed, try the following:
No update file was found on the USB memory device. Store the file in the USB memory device’s root directory.
Try disconnecting then reconnecting the USB device or storing the update file again. If the error still occurs, try using
a different USB memory device.
4. The software update will start. Please wait. The OSD display will turn off during update and the words ‘UPDATE’ will flash on the front panel.
5. If ‘COMPLETE’ is displayed, updating is completed. The screen will return automatically to the play screen.
# If ‘FAIL’ is displayed on the front panel display, updating has failed. Try the following:
Turn the receiver’s power off, then turn it back on and try updating the software again.
Try disconnecting then reconnecting the USB device or storing the update file again. If the error still occurs, try using a different USB memory device.
DSP firmware update

2. Press the SPEAKERS and STANDBY/ON keys simultaneously to enter DSP UpDate mode. ("DSP UP" is displayed.)
3. When "PLAY" is displayed, playback of the .wav file starts. (Play the file only once. NEVER repeat playback.)
("PLAY" is displayed.)
4. After playback is finished and "ENTER" is displayed, press the ENTER key on the front panel. ("ENTER" is displayed.)
5. "WRITING" is automatically displayed.
6. After writing is completed, "COMPLETE" is displayed.
7. Turn the unit off then confirm that the version has been updated.
 IDLE CURRENT ADJUSTMENT
When any component parts which are within the red square on the following circuit diagram are replaced, the idle current adjustment of that channel is required. (Idle current adjustment for another channel is not required.) However, when any capacitors are replaced, the adjustment is not required. (The following circuit diagram is for SL channel, but another channel also has same circuit diagram and same adjustment is required)
