Understand but shouldn't the 990 screen show the menu? Also I've gone wrong somewhere as there is no sound or picture and I hope that is a function of not doing the set up but I tried a CD and no sound. Optical form sat box to 990as is DVD and Cd. DVI to DVI from DVD to 990. HMDI from Satbox to 990 and out put from 990 to DLP TV HMDI/DVI.Balanced cables from 990 to 7500. Five Orb speakers to the 7500 all match and correct polarization. Somethings wrong.
