Reset TV after repair.

Hi. My 10 years old Grundig CRT TV lost the Horizontal and Vertical signals to the Tube.

I managed to repair the TV by replacing the Philips IC that controlls the H/V signals.

Since I replaced the TV with a new LCD i'm gonna put the CRT in another
living room that has a small TV.

Now I would like to Factory reset the TV in other to propper tune the channels.

I can't seem to find a reset option in the service menu.

How do I reset a Grundig ST 70-602 NIC/TOP Black CRT TV?

Just retune them, no need to factory reset anything - there wouldn't be any point.
