Home Theater Questions? Ask a Technician for Answers ASAP
Hello and sorry you're having problems. Is Cable the only source that does not have sound? Meaning if you select another source such as a DVD, or even the built in Tuner, there is sound?
Please follow the steps below:
1) Shut the TV off, and then disconnect the cable/SAT box from power.
2) If using an HDMI cable, disconnect and reconnect the HDMI cable on both ends when the cable box is unplugged from power (make sure it's secure on both ends).
3) Plug the cable box back into power, and once it's rebooted, turn the Denon, and the TV on and attempt to watch a program.
This should restore the sound. However if it does not, then please try another source- such as a DVD player and see if that has sound. This tells us whether or not the Denon, or the cable/SAT box itself is causing the problem.
Okay good. This means you need to reset the processor of the Denon. Anytime a single port stops working it's a processor glitch, or a bad HDMI cable (I'm assuming you tried the cable that connects to the cable box with the DVD player to make sure it's not the cable?).
If you've verified the HDMI cable fro the SAT/Cable Box (whichever applies) is good, then proceed with the instructions on page 175 to Reset the Denon to Factory Defaults:
Let me know what happens please.
