First guys I am really sorry if I am posting in the wrong section. Please let me know, and I'll post in right section.

I have a Sony Surround fx900w. Been trying to use Bell (DISH) 6131 Sat. reciever remote on it. Used all the codes Bell Manual says for Sony, no luck. Also tried scanning for code, still no luck.

So been reading about av2 to av1 switch. Is there such a thing on my surround system fx900w. If so, does anyone know how to swtich between the two modes.

Or simply does anyone know the universal code for Sony Surround fx900w?

Thanks for your help guys.
