Hey guys. Not sure if I should start my own troubleshooting thread but it does pertain to Denon AVR 1613 so here goes...
I've owned the 1613 receiver for six or seven years and never had a problem, ever, until last month. The cable/sat HDMI port would not play audio, but shows video just fine. I simply switched the HDMI port and leave cable/sat unused. This week something else happened, possibly related but am unsure. My powered subwoofer, an aging Atlantic 352 PBM, suddenly stopped waking up from standby. I have a small child who loves remotes and may have changed some settings, so that was my first step, but nothing appeared different. I then began the Audyssey setup and noticed upon completion that the subwoofer, in standby, is not detected. I unplugged the sub out rca cable from the receiver and touched the cable end, no dice. However, the subwoofer pops on if I touch the cable end to the outside edge of the sub out jack on the receiver, whether the receiver is on or off. If I quickly repeat the Audyssey setup while the sub is active, the receiver will detect the sub in-menu, but still doesn't send a signal during movies or games. I was able to bump the source input up and set the speakers to small/lfe+main and occasionally get it to wake up, but not how it normally would. I tried all of this over again after a reset of the microprocessor to no avail.
This subwoofer has variable input - should I use it, or just straight THX?
Thanks in advance. Does this seem like human error or more like a part of my hardware failing?
