Hi im Ricardo

i have a problem with my philips 14PF6826/01
If i press the menu buttom on the control i hget the menu but without the installation part.

I had this problem before they did a kind of reset from the software or something. Told me i can do it by my own as well if it happend again.

But i forgot how to do it.
So please can someone help my out to get my installation back in the menu. So i can search for my chanels.
