Over the last month or so my T755 has developed blue video noise coming out of the hdmi switcher for high def sources, i know its not the cables or the display because the problem goes away when i take the receiver out of the mix and the cables are all new and have never had this problem before over the last 2.5 years of ownership. It has gotten worse and blue staticy lines flash on the screen as well now, nad has told me that it is merely a switcher, no scalers or processors are on the hdmi board and also no audio comes in through hdmi, from what i can understands it comes in and then goes right back out. Am I correct in thinking that I just need to replace the hdmi switcher board inside? could it be anything else? Is this a common problem -- i can not seem to find anything else like this problem.

If your TV is an older model and only has a couple HDMI ports, but you have several media sources, such as Blu-ray players or video game consoles, an HDMI switcher is exactly what you need. Connect all the media sources to the HDMI switch box via anHDMI cable and then connect the HDMI switcher to the TV.

I don't think that cord will work. HDMI carries video and audio signals, you might get video but probably no sound. You might as well try anyway though so here goes... The red green and blue plugs are your video and the other red plug and the white plug is for stereo sound. The yellow plug is just a lower quality video plug. So plug in the red blue and green plugs into the component video inputs on the TV then the red and white plugs into the audio inputs. DON'T plug in the yellow plug. If this doesn't work go to your local home theater store and ask for a receiver or switcher that will downscale high def HDMI to component video and stereo audio. You can probably pick up a cheap one for around $100. Good luck!

Don't used the Blu Ray player on the tv HDMI out put hub.Used the connections for of the Blu Ray player connections by a S-Video cable for the video and the RCA component cable R,W for the connections for the audio out.The high Def.cable box will not work for high Def. this way,but the Blu Ray player will.

YOU HDMI SWITCHER IS DEFECT OR YOUR TV IS NOT COMPATIBLE

Have you proven that a straight shot HDMI to the TV from either source solves the problem?

For all we know the TV or it's HDMI cable could be faulty.

Make sure ALL your plugs are properally plugged in (green goes to green) and make sure you are on TV on the HDmi switcher (it is the thicker bottom of the cord that you plug into the xbox.) HD switch has some problems.

Your TV plays High Def material through either Input 4 (uses component cables R,G,B) or through Input 5 (Uses DVI cable).
Today most equipment uses HDMI cable for High Def or it may have a component (RGB) output that you can use. The DVI hookup is best, so you need a HDMI to DVI cable or Component Cables (Red, Green, Blue). You need some source that OUTPUTS High def (ex. 1080i) either through HDMI or component cable. You need to either connect the component cable(R,G,B) from the source to the Input 4 on the TV or connect the HDMI to DVI cable from the source to the Input 5.
You need to set the AV source on the TV to AV5 (if you are using the DVI input) or AV4 (if you are using component cables).
If you want to play Highdef source like Blue Ray then you can just connect the output of the blu ray player to your Tv using either the HDMI to DVI cable or component cable (Red, Green, Blue) and set the TV input to AV5 (for HDMI/DVI) or AV4 (for component).
But if you are trying to get Free High Def from an antenna then you will need to have a component that can OUTPUT high def. The $40 converter boxes don't do this - they simply convert the Digital signal to Analog (non high def). What you need is a High Def TUNER that OUTPUTS High Def. I was looking for one for this same reason and ordered the centronics ZAT 502 HD. But it cost about $80. Then I saw that Tivo had an upgrade deal where I could upgrade my existing Series 2 Tivo to Tivo HD for $99. It has a High Def Tuner in it. So I cancelled my order with Centronics and got the Tivo. In any case if you want Over the air HD you will need a High Def Tuner that will OUTPUT 1080.

Hi, first of all you need a high definition source. I'm not sure if your cable box is HD but lets take it as an example. The component leads which you are using isn't 'true' HD video quality, what you need is a hdmi cable from your source to your TV.

Your cable box maybe HD with a HDMI output, if it is then you need the lead to come out of the cable box into your tv's HDMI input using a HDMI lead. Then you switch your TV's source to the HDMI input and it then should be producing a HD quality picture, but to truly get the full HD experience you may want to subscripe to a HD channel or purchase a blueray player becasue most cable TV channels are upscaled to HD and the definition is not as good as on a blue ray disc or a true HD channel.

So in conclusion the cable and input you are using is not designed for HD input. I believe your TV is HD, check for HDMI inputs or DVI inputs.

Hope this explains your problem

s-video is a legacy connection. legacy means obsolete and this will impare your image.

what you should do is connect the cable box and blue ray directly to tv with hdmi cable, then run audio cables back to the reciever from these devices. the vcr and regular dvd player would be routed through the reciever the conventional way. you would have to change the inputs on the tv between the cable box, and blue ray if u have one, and a seperate single tv imput for components running thru the stereo. you would have to use the reciever to select between audio sources, and the video sources between the vcr and dvd only.
