Lost picture on my AVR-2807

Change the hdmi cable and try. If not then you have an hdmi fault module.

Check the speaker setup configuration in the setup menu. Many times the surround back speaker terminals can be assigned to something else like zone 2. They may just be turned off.

The best possible solution to your problem is :
Connect your blu ray player directly to the HDMI input of you Plasma and watch HD video....
and connect the 5.1/7.1 sound thru the optical or the coaxial link directly to your AVR 3805.
You will not loose anything on the Blu-Ray.
The sound is best processsed by the AVR3805, while the video, which is the real upgrade (BluRay) in terms of resolution of picture would be processed by your plasma.

Connect and Enjoy

hello if you know this spitter conduct voltage and its feed from main device and when you connect another it send it ground you have to do this chech with a voltmeter in the hdmi splitter output is not dc present if so change it cause is not blocking dc current saludos

the Denon does not pass 1080p change the output res from the DVD/PS3 or Xbox to 720p or 1080i will solve the problem

Well,i can tell you are not very focus,cause you posted Denon AVR-2807 with Bose AC 15 problem,but under your details,you put down AVR-5807!
First of all,it is so unfortunate that you are NOT able to gain and experience to true ability in sound for this wonderful receiver when you are using a dual tweeters speakers and expect to have good sound separation as a TWO WAY speakers(a tweeter and a midrange-for true high frequency and mid frequency sound separation.)
Secondly,you have defeated the audio configuration of the Denon AVR-2807,since all your speakers are control BY the Bose subwoofer.
Now,i could show you a way to hook this up,and it doesn't matter how you connect them, they are the "bicycle tires" installed with a "Porche"engine if you know what i mean.
If you want a good recommendation for your "beast",i will more than happy to show you the way!
Cheers,

Have you changed the connections recently? If so, maybe something got plugged back in differently.

Otherwise check the AVR-2807's System Setup. There is a menu to associate different video inputs to each of the audio inputs. Probably the input with sound doesn't have the right video input associated with it, though I'm not sure you can associate a video input with the CD input... which tells me maybe the connections got changed?

El amplificador de audio IC esta dañado por eso no existe audio hay que remplazarlo.

cant use both hdmi and opti outs try sum setting in blue ray but u nee dto plug all blue ray dish directto samsung hdmi then 1 master digital out form tv to sterio digital i n ok tell samsung your output also

Finally the problem was with the HDMI cable. When I pushed it in on the TV set the problem disappeared. It seems the connections must be quite firm on the HDMI cables otherwise anything may interfere to the sound.
