Home Theater Questions? Ask a Technician for Answers ASAP
Hello, First- have you tried simply rebooting your cable box by pulling the power cord from the wall to the box for 10 seconds and plugging it back in? That is THE most common cause of lost sound that we see. If not try that.
Additionally, all of those wires disconnected behind your Denon are VERY very bad news! Any of those wires can accidentally touch each other or the chassis of the receiver, or any of the other jacks on the receiver and cause a short- and bam- no sound and a receiver that requires service.
That said, I am more concerned with the cable box getting rebooted at this point, however if the issue goes beyond that, then I will need the FULL model number off of the front of the Denon please.
