During internal test from unit, Front L/R, Center and Subwoofer all OK. No sound from rear. Checked all settings on unit. I have a Toshiba DVD/VCR Combo Connected using Optical and also using analog A/V to the unit. CD changer and Cable Box (Coaxial Digital) all OK. But no rear speakers! I connected one by one and polarity is correct. During DTS and Pro Logic II movies, Front, Center and sub OK but still no rear. Any suggestions?
Assuming all connections are correct, when you run the internal test tone, see if you can raise the volume level of the rear speakers after the receiver rotates to that position.
