It's taken 4 years but I finally connected all the parts (bought the Onkyo AV receiver & Axiom speaker 6.1 set-up, then decided to move to BC. So left in the boxes for ~ 1 yr, moved out here & played outdoors too much, then had to build a ET system...more tools to buy & courses to take to learn cabinet making, then too much $$ from day trading, off to Europe for several months...or cat powder snowboarding etc.) Now I'm back to work & trying to get the 6.1 system working

All speakers work when running set-up "pink sound" except the sub-woofer EP 175

Using input 1 (Component Video + optical audio) from my HD Sat receiver, I get picture (plasma 42", output component video) & audio from front speakers only
Using input 2 (component video & optical audio) I only get audio from front speakers, no picture.
Have been all thru the hardware & software & troubleshooting in the manual...no success.

anyone else running Onkyo? any suggestions? TIA

you may accidentally have turned on speaker "B". if you try to change surround mode and it displays not available noew or something like that is what it is. i have the 600 also look closely at the display it will show if be Speaker "B" is enabled. Good Luck.
