Mitsu WD-52725 No Digital Audio

Recently got a WD-52725 Mitsu 52" DLP Set. An Awsome set. The only thing I have not been able to get to work in the coaxial Dolby digital out. I replaced the cable that came with the set with one I know works. I know it's not my Yamaha receiver (trust me on that). I get analog audio out no problem. I have my STB set as Dolby Digital Out. Using the Component or HDMI input I have no problem getting Dolby Digital from my STB. I just upgraded the Firmware to version 4.05. Didn't help. The digital audio connector on the back of the Mitsu set does not seem to be active. The only I haven't touched yet is setting up "Net Command" as I have no interest in letting the Mitsu remote control any of my other equipment. Is there something in Net Command that activates he Digital Audio out? Have I missed something??

You should get digital audio out if using the internal digital tuner, a Firewire source, or an HDMI connection. Theoretically, DVI input should have a DIGITAL audio input so it could feed the digital out as well, but I'm never seen a TV designed like that. Your Component input only has analog audio in associated, so it can't pass thru digital.

You probably have a configuration option for internal or external sound decoding somewhere in your TV setup menus. It's not a Firewire (NetCommand) issue.

I have a Wd-62825. I thought I had the same type of problem when I used ota. I wouldn't get any sound through my surround sound processor. Look at pg 15 in your owners manual. It works on digital only. But if you record in analog. When using tv disc it converts analog to digital. hope this helps it drove me crazy for a while. Good luck Tom T.

i have same tv and had no problems their could be a problem with your coaxel jack. if the channels are not coming in in digital you will not get sound through your receiver. go to the set up menu and scan for channels and check the prefer digital box..

hook up the audio outs from analog and digital, your rcvr should have an 'auto' setting, and it should be all good. I have no problems using the internal tuner/tvdisc this way.

note: this tv (and any others I have seen) will not pass digital audio from the HDMI to the coax digital audio out. You will have to connect audio seperately from the source (unless you have an HDMI rcvr)

rereading your original post; and it doesn't sound like you have any audio cable coming from your set top box. you will have to hook that up from the STB to the rcvr. either coax or optical, directly to the rcvr. hope this helps,

Seems wrong not to pass on the digital audio from HDMI when the TV doesn't decode it! DVI inputs should ALSO have associated digital audio that should be passed along. This gives the set a chance to insert audio delay if it has to do any video processing... keeping sync.

Not saying it's not so... just that is SHOULDN'T be...

Rsawdy,
I totally agree with you. Mits cust service cannot give a decent answer on this. all I can figure is that the HDCP protocols were written that way. For instance, they told me that the protocols specify that the monitor be on before the STB! is that rediculous, that it couldn't be made to have it all turn on at once? also, it may be that it was written this way so we would all want/need to upgrade our recievers.

There is a problem with turning all off at once... if you mean by way of a powerstrip. TVs need to do their shutdown routines, cooling bulbs especially...
