This is typical. Your Denon has "assignable" inputs for both audio and video.

Basics... your AVR is not processing the correct video input of the source selction you have pressed.

I hate to be the pain here but, you are going to have to read the manual related to your Denon model # in order to figure out how to change these settings.

Usually it is not very hard. I suggest going to the Denon website and downloading the manual for your unit. After reading though the manual (usually toilet reading material) you will understand how to change and assign these settings/inputs.

Good Luck...

I have picture but no sound. We just had our surround sound system go out and are trying to run our tv on it's own internal speaker system. How do you hook it to our direct tv hd box


Hi.

You need to use audio cables. Connect two red and white audio cables from the output on the HD box to the relative input at the back of TV (nr.4 in picture below). The best way to connect the HD box is by using component cables, that are the red-green and blue trio of cables, plus a white and red audio cables.

Here what you need:

Three plus two:
Component Video Cable
Audio Red / White Cable

or single set of five:
Cables Unlimited - Video / audio cable

Once you have the five cables, connect them to the output at the back of the Direct TV box, and then connect the other end of the cable to either group of connectors 6, or to one of the columns in connector 7. Do connection with box and TV power off. After re-applying power use the source-input selector on remote to select the source from Direct TV box.

The screen is green no color at all it makes aloud humming sound what is the problem we replaced the lamp last year


Do you have a cable box going to the TV and is this condition on all of the inputs or just one. Chances are you have standard video connection plugged into the component inputs.

If you have a (yellow/red/white) cable make sure you have it plugged into a connection on the tv that matches those colors because if you have a standard video (yellow) plugged into the Green then you will get a black and white picture.

If you are plugged into a component connection you will need a total of 5 RCA style wires. One will go from Green to Green, another from Blue to Blue, another from Red video to Red video, anther Red audio to Red audio and white audio to white audio.

The common mistakes made with this connection is the reversal of the RED video and RED audio which will cause the humming noise you spoke of as well.

Thanks,
Robert

No picture no sound loud humming sound for a short period when you turn it on than a orange light flashing at bottom where the blue light is when you turn it on.


AV cables reversed perhaps. Sounds like VIDEO (Yellow, Green, Blue or Red) cable is plugged into the AUDIO section. Perhaps you have switched the RED (Left audio) cable plugged into the RED (Component) Video cables. This would account for the loud buzz and since the set isn't getting an image it goes into standby mode. Just a thought.

Hooked it up to a blue ray player, no cable at all, just the blue ray, and i get no sound from the tv, just a picture


Hi,
To connect the Blu-ray player to the TV, connect the Video OUT of the Blu-ray player to the VIDEO 1, VIDEO 3, VIDEO 4 port on the TV using the "RED/WHITE/YELLOW" Composite cable to get both audio and video. You may also connect the "Component OUT" port of the Blu-ray Player to the VIDEO 5 and VIDEO 6 port on the TV using the (Red/Blue/Green/Red/White) Component cable to get both audio and video from it. If you have any questions on connectivity, you may wish to reply with your query.
Thanks,
Pradeep

Signals to the tv from other sources and the image is P and G


Soon as though you have your wiring mixed up. Those leads, colors you describe are for Compnent Video signal....Red Green Blue. Now  the Others  are for Audio Visual signal , Yellow, Red, White... They are NOT compatable. IE: You cannot mix them. Check in your manual as to what  types of lead is needed how to wire it up..

Hook up sony blu ray


You should be able to hook it up with a component video cable. A component video cable is a cable that has 5 color coded RCA style ends that are Green/Blue/Red/White/Red. The Green, Blue and one of the Reds is for the video and delivers the signals needed to produce the HD picture and the White and the other Red is for the audio to provide you with stereo sound.

The Video cords will plug into the section labeled component video facing up and down and the audio will plug into the side by side section. So if you plug into Component input 2 then you would plug in the audio into the audio section of input 2.

If you have a separate surround sound system you can connect one of two ways.
1. Plug a separate Audio (red/white) cable from the Blu Ray to an available input on the surround sound.

or

2. Plug all inputs into the TV (as noted above) and then plug a separate Audio (red/white) cable from the tv labeled "Audio Out" to an available input on the surround sound system.

Picture is red


If you are running component video, make sure the blue is plugged in and in the right spot. Component video works like this: the green is a black and white image, the red and blue are cover overlays to make the image display properly. So if everything looks plugged in right, then try plugging in a composite video (Yellow) or S-video cable switching to the appropriate input, and see if the image is still red. If so, go to the set up and set the set to factory defaults, and see if that fixes the color issue, It's possible that the color settings on the TV are messed up, with the S-video plugged in go through the set up menu and see if you can correct the color issue IF THE IMAGE IS STILL RED WITH THE S-VIDEO OR COMPOSITE VIDEO, otherwise the issue is a problem with the component video cable.

Hi,

Get the Wii "COMPONENT" cable set. This set has white-red (sound) connectors plus the red-green-blue (component - video) connectors. You can get this cable where they sell the Wii. It will give you the best possible picture with this device.

Plug the Red-Green-Blue connector in their respective sockets on the NEC display (upeer right-hand side). Switch the NEC display to the DTV/HD input (upper right button on the remote).

Please note that this setup does not provide sound since the display does not have speakers.
Use the white-red connectors and plug them into your amplifier or other sound device.

Good luck.
