Problems with coax port Yamaha RX-V520

<font color='#000000'>Hello, new here, so forgive me if I've posted in the wrong group.. &nbsp;Also posted this in Interconnects forum.. &nbsp;dunno!

I have had a Yamaha RX-V520 receiver for about 9 months, and just recently noticed that my Time Warner channels digital channels are not sending digital audio to my receiver!

Here's the way I have it hooked up and set up:

Analog L/R on Cable Box to Digital Cable L/R on Receiver
Digital Audio Coax on Cable Box to Digital Coax Audio on Receiver

The Yamaha RX-V520 allows you to assign the Digital Inputs to go with any of the Analog equivelants (in my case this works well because my cable box has ONLY a digital coax and no digital optical, so I had to reassign the port). &nbsp;In the menu settings for the Yamaha RX-V520, the default setting for the Coax Digital audio is the CD Player, but I made sure to change it to Digital Cable. &nbsp;

The RX-V520 automatically detects which ports (analog or digital) to get sound from, and digital has priority if a signal is present.

Up until who knows how long ago, I was receiving my digital cable stations in digital audio, not analog. &nbsp;I knew this, because when I first bought the receiver, I didn't have any analog cables, and thus my analog audio channels had no sound, while my digital audio channels did. &nbsp; But now, I get no indications that I am receiving digital audio (no &quot;Dolby Digital&quot; on my Yamaha screen, and when I disconnect the analog cables from the receiver, I get no sound with just the digital coax plugged in). &nbsp;

I verified that the input is set to D-TV Auto and not D-TV Analog. &nbsp;I've tried a new Digital Coax cable, I've tried a new cable box. &nbsp;I have not yet tried new cable tv coax cables (the 75 ohm or whatever they are, antenna cables) and I have not tried to have the Yamaha receiver serviced.

What are the odds that the Digital Coax input jack are bad on the Yamaha receiver? &nbsp;I treat my receiver with care, and with the exception of the first week I owned it, have it in a well ventilated area. &nbsp;Are there any &quot;secret&quot; diagnostics I can run on this receiver to tell if this jack is live or dead? &nbsp;Or, is there a tester I can buy?

I really don't want to disconnect all 20 or so cables from this thing if I don't have to in order to get it fixed (if it's really not broken).. &nbsp;Aahhhhhhhhhhhhhhhhhhhhhh.

Thanks,
Jeff</font>

I recently got the Yamaha YHT-150 home theater in a box system from Best Buy when I bought my new HDTV. This Yamaha set is in my bedroom since I already have a nice stereo in my living room. This home theater uses Yamaha's HTR-5730 receiver and I've got the exact same problem you are describing. My digital audio coax will not work. I too have tried two different cables and two different boxes and it won't work. The optical works but my cable box doesn't have an optical output. Did you ever come to any resolution with yours? Thanks.

LSUMatt1514 I doubt you will here a response from jeffrok since that post was from 12-30-2002, but perhaps someone else has some input for you.
