I am attempting to hook up 990/7125/LFM-1 for the first time (DVI / Plasma output, Cable Box + SACD/DVD inputs). Net net, after hours of work, and confirmation that all lines are appropriately connected, I can get no sound whatsoever. Video switching seems fine, butaudio is null and void. Several items suggest a bad 990:

1)No Sound.

2)Remote appears inoperable. Backlights work, but all of the functions actions on the 990 remote incl. volume, select, switching… just seems dead.

3)In the set up of the default surround sound mode, the unit will not switch out of PLII MV +DH1

I suppose there is also a problem with 7125 amp, but given the other items above, the 990 seems to have a manufacturing defect.

Suggestions???
