The user manual is split into two parts. It's not in the Guide, it's in the Reference Book (page 30). You can do the adjustment with almost any B&O remote, as it's done with the help of a screen menu. See the picture below.

Hi, thanks for the info but when the menu button is pressed only  TV, DVD, SETUP, TEXT  options are opened with the < or > buttons. The SETUP menu doesn't give access to picture controls.

Could the previous owners settings be blocking the other menus and if so, how can the tv & remote be reset ?

I downloaded the 40 page Guide but can't find a Reference manual.

Apologies for pointing you in the wrong direction. As may be clear by now, I don't have a BV1 myself. What I do have is a MX 4200, which should be closely related to the BV1 from a software point of view. At least I thought so. And the instructions I posted were indeed from a BV1 Reference Book.

Easiest thing first: finding the BV1 Reference Book. You are perfectly right, there's none such available from the B&O site. I think it was originally provided on a CD that came with the BV1. However, if you upgrade your BeoWorld membership to Gold or Silver, you can get it from our archive!

There seems to be many slightly different BV1 versions. The one you have (LS) may not offer picture adjustment from the user-accessible setup menu. The only way would then be to enter the service mode. When in the user setup menu, press the sequence 0 0 GO on your Beo4 and you should get into the menu structure shown on the picture below. Be very careful – there's scope for creating serious mayhem here.

Did a reset and changed picture settings.

Thanks
