I forget admin password set on the system in the Security screen in the UI,Now i have to change some configuration on the unit
is there any way to clear the password?
Default password is usually the system S#, 14 digits starting 82 or 88. Alpha characters in the S# MUST be upper case. If this default has been changed & the new password lost, the only recourse is to factory default the unit.
Turn the unit off. Now hold down the "0" button & turn unit on. Keep the "0" button down until you can see that the LED is flashing accepting the IR Remote input.
The VSX will now boot into a screen that looks like a BIOS & acquire a DHCP IP address.
Check the bottom right hand side of this screen to ensure Security Mode is OFF. More on that later.
At this point you can flash a new image to the device, probably best to choose a Custom install when offered typical or custom.
The Custom option allows you to do a ERFL or Erase System Flash Memory.
Once the update is complete the VSX will be as from factory with the default password (S# upper case).
You may need to s/w update it back up to latest version.
At the reboot into the Boot UI if this is ON, contact your supplier. The abilty to circumvent this feature is controlled to protect the integrity of Security Mode.
