Panasonic TC-55AS680U Forgot Password

[jason123]

Hi folks,
I got this TV and I'm trying to reset it before selling it. I go to settings, then System and click on "Factory Defaults" it asks for a password. Tried the 0000, 1111, 1234, ... and no luck.
Any ideal how to reset this TV?

I got the service manual, attached, there is a Factory Defaults (Page 9), so I put in the values as listed.. unplug AC and reapply AC.. nothing happens.. I'm missing a step maybe?

Help is much appreciated
Thanks

Looks like full TV reset is holding down the Volume - on the keypad on the back of the TV, while pressing "Menu" on the remote for 3 seconds or more.
