Interference "wave" appears when my Blu Ray is connected via DCI to HDMI

Optical leads have a red light that shows even when unplugged. If that is not on the socket is switched off.

The usual way is to connect it via a HDMI cable, for which the TV should have 2 or 3 input ports. You then select this HDMI as input on the TV to see a DVD playing.

Get a "high speed" HDMI cable. Some will say there is no difference between any HDMI cables, but they did see fit to increase the bandwidth in these cables for Blu-Ray DVDs.

Red and White are audio, yellow is video. On the back of the TV there should be a yellow jack if it takes external inputs. There are two ways to connect your Blu-ray Player to your amplifier. Via HDMI output: Connect the player's HDMI OUTPUT to the corresponding INPUT on your amplifier using an HDMI cable. If your amplifier has an HDMI OUTPUT, connect that to the HDMI INPUT on your TV using an HDMI cable. See if these links help.

Obviously if you gave better information you would get a better answer.

The DVI adapter stops the audio. Use the audio out ports on the bluray player to connect an audio pair cable to the tv.

Check your sound settings on the dvd player should be pcm
Turn off dvd player and tv and make sure tv is turned on first

onkyo receivers have a problem, see

If you would like to use high definition audio decoding, connect the HDMI from the blu ray player to the receiver. If that it not an option for you due to lack of equipment such as an additional HDMI cable to go from the receiver to the television for the video portion of the signal, then connect your optical cable again. After the optical cable is connected, make sure the Dolby Digital decoding is enabled on the receiver, and that the media you are playing also has a version of 5.1 surround sound. Then, enter the setup menu of the player (which I suspect this is actually where the problem might reside in your case) and make sure that Dolby Digital and DTS are not set to "downmix." Dolby Digital should be set to output Dolby Digital and so on and so forth...hope this helped.

I have a similar problem. The Sharp TV aquos appears to be shutting down my blue ray player and dvd recorder when connected via HDMI. They work fine and never close down when I connect them via the rca cables either single video connection or a composite 3 cable rca lead. I have 3 HDMI inputs on the tv and the problem occurs on all 3. Any suggestions?

You say this doesn't happen on regular cable or when playing a regular DVD. Hmm. Is this Blu-Ray player connected by simplink? HDMI is a bi-directional format cable, so  there are cases in setups where your tv can send commands to your blu-ray player and vice versa. It could be a problem with your blu-ray player that it is sending for some odd reason a mute command to your tv. Or is processing a command that your TV interprets to be a mute command when playing blu-rays. Because if it was the TV itself chances are you'd see this when watching a normal DVD or on cable as well. Since you say you're not, it leads me to believe the issue lies with the blu-ray player itself. 

hi there,

1-connect the blu-ray to your tv via hdmi cable and this will run picture.

2-connect the blu-ray via digital optical cable to the optical input on the bose system. then using your bose menu, (system menu)set your auxillary sound output to digital optical.

when watching dvd thru bluray player select aux on the bose and you're away.

good luck
