Not getting video from BD palyer through AVR

[manish gupta]

hi guys, this is my first post after joining hifi vision
I had bought Yamaha yht 299 couple of months back. Till recently everything was working fine. from last few days i am not able to view the video on TV from my BD player. It gives signal for few seconds after turning on but afterwords the screen goes blank.
My connections are as below

BD player HDMI to AVR HDMI in and AVR HDMI out to TV HDMI in

If I connect BD player directly to TV via HDMI, every thing is fine but then cannot enjoy the hometheatre.

Hi manish gupta

Certain AVRs allow limited video formats pass through capabilities through HDMI and you need to understand this better by referring to the owners manual. Sometimes if HDMI video output is kept as Auto, the screen will keep resetting itself on / off all the time....

Another most important factor is DUST.....this really affects HDMI cables and then you face erratic performance from the AVR or player...you need to ensure that the same is dust free to the maximum extent....remove the cables , gentle blow the dust and ports and re connect and try...

Are you facing this issues when playing DVDs? or a particular movie? Try using different discs / videos and see if the same issue is happening....Also your TV needs to be compatible to show the video format being played.

Hope this helps...

You may be facing HDMI handshake issues. If you're able to see the video for the first few second and then it turns blank, it's most likely that either your HDMI cable or your HDMI port (less likely though) is damaged.

Try changing ALL the HDMI cables between your BDP/AVR/TV. Don't just change the cable between BDP and AVR. Make sure that you change the cable between the AVR and TV too. I faced a similar issue with my media player and the culprit was the cable between the AVR and TV.

Dear Manish,
Try this method,
Connect BluRay to TV via HDMI.
Connect HD ready Set Top Box to TV via HDMI.
Connect BluRay directly to AVR via Toslink/Co-axial.
Connect TV to AVR via Toslink/Co-axial.

Results:
Video should work fine now.
You need to switch on AVR only when using Home theater.. For normal viewing, TV speaker will do. While using Home Theater, mute the TV.
AVR's sound will work fine when connected directly to BluRay player via Toslink/Co-axial.

You will now get potentially 7.1 output from the HD set top box and USB jump drive of the LED/LCD/ Plasma TV. The USB pen drive will nowadays, play Dolby Digital and ProLogic II x. Only DTS is doubtful.. But that does not matter since, most downloads are either stereo or Dolby Digital (AC3). New TVs support everything.. So, get a TV with USB.
Hope this helps,

But would this pass HD audio (DTS HDMA and TruHD) through optical to the AVR?

 

[Subcenter2009]

Why not?
Is there any reason why it should not work?
I have an oldish AVR without HDMI so, I am not sure.. but why would the makers of the AVR disable such a useful function?
I still think that it will work.
Try and let us know the results..:yahoo:

Hi,
These 2 sites below show that HD audio will work even in old systems albeit in a lossy compressed format as ordinary Dolby Digital or DTS.

DTS-HD Master Audio - Wikipedia, the free encyclopedia

Dolby TrueHD - Wikipedia, the free encyclopedia

Hope that info helps..

The optical would work but it would transmit only the DTS core. If I understand correctly the optical cable does not have enough bandwidth to transmit the full bitrate that HD audio requires (maybe between 2mbps to 5mbps - someone please confirm this).

HDMI does have the bandwidth to transmit these signals along with the video. Try playing any clip having DTS HD/TruHD tracks and see whether the audio received on your AVR is the same or is it downgraded to DTS

Faced similar issue with my PS3 couple of days back. Changed the HDMI cable from PS3 to AVR and issue resolved.:yahoo:

How can?HD audio can not be passed via optical/Coaxial cable due to less Bandwidth in my opinion.Even HDMI 1.2 cant pass it.

Thanks guys. There was some dirt near the ports. Cleared it. Started getting the signals. But momentarily and intermittantly signal goes off but if u leave it like this the signal comes automatically. Just wanted know what is the better option
1.connect bd player out to avr hdmi in and avr hdmi out to tv hdmi in
2.connect directly bd player to tv via hdmi and avr to bdp via coaxial
which will give better sound results

 

[manish gupta]

I have used the second option for my hd STB

 

[zervinb]

Theoretically, the first option is the one to be used. It will give better sound for blu-ray movies.

EDIT: For STB, it doesn't make a difference, since DTH gives at the max Dolby Digital sound, which is carried by coaxial. So HDMI or coaxial, won't make any difference.

 

[manish gupta]

Thanks. I have now connected the bdp with the first option I.e bdp hdmi out to avr hdmi in and avr hdmi out to tv hdmi in. I tried playing dvd of The dark knight rises. The avr displayed the audio as 2.1 and not 5.1. When I used the prologic option of the avr then only the sound came from all the channels. Why is it so. The dvd is in dolby digital.

 

[zervinb]

Change the audio stream on the player, so that it uses the 5.1 Dolby Digital stream. You can also select the stream from the DVD menu.
