No audio I tried setting up the actiontec mywireless hdtv. I have video on all screens but no audio. All HDMI cables are new and properly connected. All firmware and software is up to date. It works for gaming systems and DVD players but not through my cable box. I have tried using powered splitters and then tried running through a receiver but nothing works.

Page 18 of the manual, you shouldn't need to do steps 2 or 3.

CONNECTING A COMPONENT SOURCE WITH HDMI or DVI CAPABILITY TO INPUT 1 or INPUT 2
1.Connect the HDMI or DVI to HDMI connection cable from the output of the HDTV set top box or DVD player to the HDMI input as shown on the AVC Center below.
2.With DVI output, connect the cable from the AUDIO OUT R of the HDTV set top box or DVD player to the INPUT (AUDIO/R) jack.
3.With DVI output, connect the cable from the AUDIO OUT L of the HDTV set top box or DVD player to the INPUT (AUDIO/L) jack.
4.Press the INPUTS button, then select INPUTS 1 or 2 to view the program from the HDTV set top box or DVD player. The VIDEO OSD label disappears automatically after approximately four seconds.
5.Select ANT A or B from the INPUTS menu to return to the previous channel.
NOTES:1. Completely insert the connection cord plugs when connecting to rear panel jacks. The picture and sound that is played back will be abnormal if the connection is loose.
2. The HDMI input on INPUT 1 or 2 contains the copy protection system called High-bandwidth Digital Content Protection (HDCP). HDCP is a cryptographic system that encrypts video signals when using HDMI connections to prevent ******* copying of video contents.
3.HDMI is not a "NETWORK" technology. It establishes a one-way point-to-point connection for delivery of uncompressed video to a display.
4.The connected digital output device controls the HDMI interface so proper set-up of device user settings determines final video appearance.

Check the input selector on the TV, if you have audio only then it is a cable problem,
that means that cables are not connected in the right way.

There might be a setting on your cable box for audio output. Use the cable remote and look in the audio section of the settings menu and select HDMI output. Mine is under Audio Digital Output in the Audio/Video menu.

Hi
Do you not have a HDMI cable or HDMI socket in your TV ?

Step 1:

Connect the audio/video input of the component cable into the "A/V" port located on the back of the xbox 360

Step 2:

Match the red, blue and green cables on the other end of the component cable to the corresponding component ports on your HDTV. If your HDTV has more than one set of component inputs, make note of which one you use.

Step 3:

Slide the switch on the component cable to "HDTV."

Step 4:

Turn on your HDTV. Set the video mode to the component port that will be used. HDTVs with multiple component ports will usually be labeled "Component 1," "Component 2" and so on

Step 5:

Turn on the Xbox 360. Go to "My Xbox." Select "System Settings" then "Console Settings" then "Display" and then "HDTV Settings." Choose the display setting (720p, 1080i and 1080p) that is best compatible with your HDTV. If you're not sure, try them all until you find the one that looks best.

Step 6:

Disconnect any previously connected A/V or component cables.

Step 7:

Connect the HDMI AV cable connector to the "HDMI AV" port on the Xbox 360.

Step 8:

Connect the other end to an available HDMI port on your HDTV. If your HDTV has more than one HDMI input, make note of which one you use.

Step 9:

Turn on your HDTV. Set the video mode to the HDMI port that will be used. HDTVs with multiple component ports will usually label them "HDMI 1," "HDMI 2" and so on.

Step 10:

Turn on the Xbox 360. Go to "My Xbox." Select "System Settings" then "Console Settings" then "Display" and then "HDTV Settings." Pick the display setting (720p, 1080i and 1080p) that looks best on your HDTV.

Its a vidio/audio input which looks like this. If you have an hdmi port on a laptop you can connect it to a TV and have the audio and video transfer to the TV.

Hi andy838,

I see that you LG LCD HDTV is giving you a No Signal message on the Screen.

see steps Below on finding out what will show video on your LCD HDTV.

* First make sure that the HDMI cable is connected to your Laptop to the HDTV LG.
* On your TV check your remote control and look for the input or Source Button, this will help you set your TV for the HDMI connection.
* Once set, turn your Laptop on and see if the HDTV will provide Video from the Laptop to your HDTV using HDMI.
* I believe that works right, now we have video still we need to set the Audio to work from you Laptop using HDMI to your HDTV.
* On your Laptop lower right side look for your speaker icon, right click on the speaker icon then select Playback Devices.
* Once you've selected Playback Devices you will see a window showing you a list of devices and the first one on the list will be you HDMI connection right click on it and select set as default device this will make your audio work on your HDMI to your TV.
* Once audio to HDMI is set and you want to go back to your Laptop just set the speakers as the default device this will set your speakers have the Audio working again on the Laptop.

I hope that this will help you regarding your concern.

Have a nice day,

Your Bravia should have a 15 pin PC input, this input can take most standard PC resolutions, however if you a have a video card with an HDMI port, you should set your resolution to 1920 x 1080 @ 60Hz refresh rate so that the signal can be recognized and processed, many standard PC video resolutions are not compatible with the HDMI inputs. You should not require audio cables unless you are using a DVI to HDMI connection.

I was using an hdmi cable purchased online. A friend told me that it might be the 'cheap' hdmi cable. I tried a set of Monster hdmi cables and problem solved. So all hdmi cables are not the same.

Connect the HDMI outputs on your various components to the HDMI inputs on your receiver. Connect the HDMI output on the receiver to the input on your TV. HDMI incorporates digital audio, so no need to buy optical audio cables. If your receiver does not have HDMI inputs for all your components, you will need to make a choice. HDMI = Best, component video + optical audio = second best, S-video+ optical audio = third best
