Damn, only 3 days and I found a defect on my new DA5ES. Well, I'm pretty sure I got a defective DVD/LD Coax Digital Input. I get no audio with my new digital coax cable. Optical inputs are working fine. I tested my digital coax cable on the CD/SACD Digital Coax input and ruled out a bad coax cable. Off to J&R to see if they will swap it out. Otherwise I'll have to test Sony's warranty service. What a hassel, it figures I get a bad one. Has this happened to anyone else? Could it be anything other than a bad input connection? BTW, other than this problem I'm really enjoying the receiver.
