Do you recall what threw him about the Z1? Also, did he use any of the two service modes? If so, do you remember which one? The Tuner Service Mode has a blue background for the menu settings and the Display Service Mode has a green background.
If you want to reset to factory settings, you need to go into the "self check and forced to factory setting" mode. Here's how you do it. Unplug the AC cord to exit.
"Produce TV reception screen, and while pressing [VOLUME ( - )] button on the Display unit, press [MENU] button on the RF remote control for more than 3 seconds."
**Caution** You will lose all changes and you will have to re-register your remote control to the tuner. Re-registering is easy, just follow the directions in your owners manual.
