Can yamaha htr 5830 work with hdtv without cable box

Hello James,I have the exact same issue, did you have any luck?

Make sure you have the "audio input mode" on "Auto" it's a small button on the front of the Yamaha. Then go into the PS3's Audio setup and make sure it's set to Digital. Hope this helps

The HTR 6130 only HDMI passthrought VIDEO, no sound. If u want sound u need to connect sound cables: rca, optical, etc.

make sure that the yellow video jack is on the tv out on the surround unit and is plugged into the video jack on the tv. You may have to change the input on your tv to Video1 or Video2 to get the pic to come in

The physical TV is at best a lo-fi 2-channel analog audio device. Think about it this way: Most high-end users use video monitors (no audio or speakers on board). So where does the TV-related audio come from....

It comes from the same place the TV would get it - cable, satellite, dvd, blu-ray, vcr...

So why run audio from any of those sources to the TV and back to the receiver (whose specialty is
multi-channel sound)?

I imagine your cable or satellite box has Digital and Analog Audio Outputs. The receiver needs a digital input for anything multi-channel. Select the highest-quality one that's compatible with your HTR and use it for the audio feed.

You have one coaxial and one optical digital input. I imagine your (unnamed) DVD player has one or both types and your cable box has one or both types. If you have one of each type you're golden. Run each to its compatible input on the HTR.

If they're both optical, you have to make a choice, but if they're both coaxial only you could get away with using an RCA Y-cable to bring them both in to the one input. Then for each to work you would have to make sure the other device is turned off.

The video capabilities of this unit are limited to Composite (single RCA cable). Run one from the DVD and one from the cable box Video Out to the conveniently labeled inputs that match them.

I have no idea what your TV/Monitor has for inputs. If possible run the absolute highest quality video [HDMI, Component (3 RCA cables) or Composite (single RCA cable)] to the TV's inputs along with an RCA pair from DVD and Cable Ananlog Audio Out to the corresponding Audio In's on the TV. This way you can watch and hear TV from its own speakers without needing the Yamaha fired up.

Well, first of all, the method you are using is the lowest quality. You should upgrade to a toslink(digital optical cable) or a digital RCA cable. The toslink is the best all around. But it is normal for some devices to have higher sound output than others.

If you want to get sound out to speakers use the KEFF WIRELESS SYSTEM as this will not break up or cut out.
Hope this helps.

If its a PS3 please realize that you adjust the sound options using the sound option menu on the ps3, so its possible that you have the PS3 set to RCA cable and not the HDMI therefore the optical cable isnt getting any sound from the TV

dvd and dish tv optical inputs from both dvd and tv if tv has opticl out or give optical out from hd receiver. or rc pins from hd or tv to dtv/cable input of yamaha

Is Yamaha HTR-640 a receiver? Try HDMI from PS3 to receiver or Sony HDTV. If HDMI from PS3 to receiver the you need and HDMI from receiver to out Sony HDTV. You could connect everything to receiver and HDMI out to HDTV. You can not have an HDMI cable AND an optical cable coming out of the PS3, only one or the other.
