Rotel RSX 1055 RR 1050 : OSD not working


I have a Rotel RSX-1055 with RR-1050 remote.
I have connected the MONITOR OUT Composite on the RSX 1055 to an input on my TV (Philips Magnavox, 1997).
I am not able to view the On-Screen display on pressing the Menu button or by pressing the "Enter" button when the unit powers up.
Has anybody run into this problem or has any suggestions to resolve this?
Thanks.

Thanks, I'll give it a try. I also wonder why they give you a 1050 remote but the manual refers to the 969, which has a different layout. I still don't know what the "Freq" button does as its not covered in either the 1055 manual or the 1050 manual available on-line on the Rotel site.
The RSX1055 never shipped with the 1050.
There's related info to all your questions in the upgrade/support section on Rotel's website.
