Troubleshooting:

1. If the firmware upgrade fails at the last step, don’t unplug the power cord of the monitor. Just try the upgrade

procedure again.

(a) If there is error to execute the command at or before line10 in the “bdisp.txt” batch file (for instance, the

message “Error executing batch file at line 4” shows up in the Gprobe program (see the following picture)),

please try to upgrade the firmware again.

Test failed. Test failed. Test failed. Test failed. Test failed. Test failed. Error executing batch file at line 4. Execution time: 5.72s GProbe:>

(b) If there is error to execute the command at or after line11 in the “bdisp.txt” batch file, please copy the error

line of the “bdisp.txt” batch file to “Gprobe:>” in the Gprobe program, and then press “Enter.” For example,

there is “Error executing batch file at line 16” (see the following picture). Then you have to copy line 16

“FLASHWRITE C:\VP912b\VP912_AU_V2_001_040611.bin” in the “bdisp.txt” file to “Gprobe:>” in the

Gprobe program, and then press “Enter” (see the picture next page).

2. If the firmware upgrade still fails, reboot the PC, or simply use another PC to upgrade.

3. If the above procedures don’t work, unplug and re-plug the power cord of VP912. Then try to upgrade the

firmware again if VP912 can be powered on. If VP912 cannot be turned on, that means the flash memory of

the main board is out of work. You then have to replace the main board.
