Question 2

Why does the display of the SHERWOOD RD6506 receiver not show any digital signal?

Accepted Answer

If the fluorescent display of the SHERWOOD RD6506 receiver shows no digital signal, it means that the receiver is not detecting a valid digital input from your audio source (DVD player, Blu-ray, decoder, etc.) connected via a digital input (optical, coaxial, or HDMI).

First, check that you have selected the correct input source. On the front panel of the RD6506, use the VIDEO INPUT SELECTOR button to switch between video sources (VIDEO 1, VIDEO 2, or HDMI) or the AUDIO INPUT SELECTOR button to select audio sources (CD, VIDEO 1, VIDEO 2, etc.). The selected input will be displayed on the fluorescent display. If you are using a digital input, make sure you have assigned it correctly in the INPUT CONFIGURATION menu (AUDIO ASSIGN) of the receiver.

Next, check the connections of the digital cables. The RD6506 offers three types of digital inputs: one optical (fiber optic) for VIDEO 1, one coaxial 1 for VIDEO 2, and one coaxial 2 for the CD. By default, you can also use the three HDMI inputs. Ensure that the cables are properly plugged in and in good condition. For coaxial connections, you must use a 75 ohm cable (not a regular audio cable). Optical cables must also be compatible with your equipment. If possible, test with another cable or another port to rule out a hardware issue.

Check that the source component is sending a digital signal. Connect your DVD player, Blu-ray, or decoder to the same digital input of the RD6506 and start playback. Ensure on your source device that the digital output is enabled (some devices disable it by default in favor of the analog output). The receiver should then detect the audio format (Dolby Digital, DTS, or PCM depending on your source) and display it.

If you are using an HDMI connection, make sure that the HDMI AUDIO OUT output is set to AMP (and not THRU) so that the digital sound is processed by the receiver and not sent directly to your TV. You can change this setting in the HDMI CONFIGURATION menu of the RD6506.
