USB ERROR CODES 
USB ERROR1
Detection of overcurrent to a USB device
Overcurrent (500 mA or more) is consumed at the connected USB device.
# Some USB devices, such as a portable HDD, need more current than that this unit supplies. (Use the AC adaptor for the connected USB device.)
# The USB power is short-circuited.
USB ERROR2
Detection of a medium not supported
A USB device that this unit does not support (other than the Mass Storage Class) is connected (such as a mouse, printer, or digital camera).
# Connect a mass storage class USB device.
USB ERROR3
Communication error with the system microcomputer
Communication between TCC8600-00X-EA-UG (IC401) and PEG467/469A (IC9001) failed.
# Defective connection (connectors) inside this unit
# See STEP 3 of Troubleshooting.
If a USB ERR message lights in the display, try following the points below:
# Switch the receiver off, then on again.
# Reconnect the USB device with the receiver switched off.
# Select another input source (like DVD/BD), then switch back to USB.
# Use a dedicated AC adapter (supplied with the device) for USB power.
AMPLIFIER SYSTEM PROTECTION OPERATION
DC-abnormality detection
DC detection is only enabled 2 seconds after power-on. If there is a fault in the power amplifier or a high-level signal lower than 5 Hz is input, the DC_DET port becomes “L”.
If the “L” is detected, the microprocessor will perform as following.
In the case of simultaneous detection with the overload protection circuit, DC-abnormality detection is performed preferentially to overload detection.
When a DC abnormality is detected, A.MUTE* is turned on, speaker relay is turned off, then "AMP_ERR" flashes on the display.
The abnormality continues for 3 seconds.
The power is shut off.
Power key not effective and POWER LED blinks (only for VSX-918V).
However, when the following keys are pushed so that the key input of a line and the service can be carried out, power can be on.
1 TESTMODE ON (A55F+A55F)
2 When power off, push TUNE+ key + AUTO SURR/DIRECT key continuously 2sec.
When a DC abnormality is detected and the power is shut off.)
Any other key input from front panel or remote control will not be detected.
Overload detection
If the speaker terminals are short-circuited or low-load driving is detected, the OL_DET port becomes “L”. If the “L” is detected, the microprocessor will perform as following flow chart.
When an overload is detected, A.MUTE* is turned on, speaker relay is turned off, then "OVERLOAD" flashes on the display.
The abnormality continues for 3 seconds.
The power is shut off.
HOW TO UPDATE FIRMWARE
Necessary Tools
# USB Flash Memory which is saved the firmware file ("player.rom" file).
Note: In rare cases, it is not able to update the firmware depending on the type of USB flash memory.
In such a case, try to use other model of USB flash memory.
Procedures
1. Tuner VOL to "-- dB".
2. Turn off the set.
3. Press "Standby/On" and "PHASE CONTROL" keys simultaneously for about 5 secs.
"USB" or "IPOD" will be displayed on FL, soon after that "WAITING" display will appear.
Then after about 20 secs, the current USB firmware version will be shown.
4. Insert the USB memory device containing latest USB firmware to the USB slot on front panel.
Soon "UPDT 000" will appear on FL, followed by the progress counting down.
5. When it is finished, "COMPLETE" will appear on FL.
6. Turn off the set, then turn it on again.
7. You may check the version by turning the set to off, then pressing "Standby/On" and "PHASE CONTROL" keys simultaneously for about 5 secs.
Note:
# Do NOT reconnect the USB flash memory which is saved the "player.rom" file.
# Do NOT change the function setting or turn off the power during step 5 through 7.
If you do, the updating is failed and it is required to replace the USB flash ROM on the USB module.
