WestingHouse HDMI port wont work with PC but will for xbox 360?

you have not said what tv it is and it can be the hdmi cable if it has been damaged. or the grafic chip in the xbox check the xbox on another 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.

try use a lowest resollucion 720p and after change to 1080

You should try re-doing all of the connections. Both power and video and see if that works, you should also test the HDMI port of your TV with another HDMI device to make sure it's not a TV issue.

First thing to do is check your USB ports on the console. Plug in a flash drive or anything into all 3 USB ports to test them. If they all work you have eliminated the console as the source of the problem.
Alternatively, if you believe it may be the play and charge kit itself, simply plug it into any usb on any pc with a controller attached. If the red charging light turns on, it is working properly.
If both check out it simply means it's time to replace the battery pack in the controller. They have a life cycle depending on usage, and they vary greatly.

ya the port is prob. fried man....

chances are it's the HDMI port on your 360...they are notoriously bad...does it do the same thing with your component cables?

Probably defective. Get you a new one.

Is the problem that you're using a single HDMI cable to connect your Xbox to your TV? If so, this Turtle Beach article should help... ________________________________________
HDMI and Connecting Ear Force Xbox Headphones
The current Microsoft Xbox 360 series of gaming consoles allow the use of HDMI cables for simpler hookup to home theater systems and Hi-Definition televisions (HDTV).
The Xbox 360 Elite (the black one) comes with two additional cables, an HDMI cable and a separate AUDIO cable that provides a pair of RCA jacks (red and white) and an optical digital audio output (S/PDIF Out). With this cable package, you can easily connect any of our X-series headsets and an HDMI-connected television at the same time.
This Xbox 360 HDMI Cable package is available as an extra-cost option from Microsoft: http://www.xbox.com/en-US/hardware/x/xbox360hdmiavcable/
Here's a more in-depth explanation of the Xbox 360 HDMI Cable and how it works: http://support.microsoft.com/kb/937899?sd=xbox
[NOTE 1:] The standard Xbox models do not come equipped with this cable set. The HD cable they have obscures the HDMI connector, so that the two sockets cannot be used at the same time. If you only have this stock HD connector (component video, composite video, stereo analog audio and optical digital audio connectors), then you will not be able to use the HDMI connector at the same time.
In order to use both sockets at the same time (HDMI and A/V) you'll need to purchase the Xbox 360 HDMI Cable package described above.
[NOTE 2:] The current Xbox 360 Elite Holiday Edition (Fall 2009) does not come with the HDMI Cable set.
___________________________________________________________________
Some companies make aftermarket HDMI cables for use with the Xbox 360, but these may not provide the dual RCA jacks that carry the 2- channel analog audio necessary for hookup of the anlog-only Ear Force X-series headsets. If this is what you have, you may need to find another way to connect your Ear Force X-series headset.
The TOSLINK digitally-connected X-series headsets can be always be connected using optical digital "Toslink" connections (and that's the best way to use them!).
___________________________________________________________________
The oldest white-and-gray Xbox 360 models DO NOT have an HDMI port. With this particular (obsolete) model, you cannot use HDMI connections, but you can use any of our X-series headsets.
Current Xbox 360 models all have separate HDMI and A/V ports ("sockets") on their back panels.

Here are some suggestions for alternative connection schemes:
XBOX 360 AUDIO PLAYS THROUGH TELEVISION SET:
For X4 and X41: Your best bet would be to connect the Xbox optical digital audio out to the X4 transmitter's optical digital input. Then connect the X4 optical digital output to the optical digital audio input on your HDTV or home theater amplifier.
[NOTE:] Some HDTV systems have an optical digital audio output that will not transmit Dolby Digital/DTS encoded digital audio, only stereo PCM audio will be passed. In this case, you must connect as above.
For X2, X3 and X31: You can use the Headphones jack or the Audio Out jacks on your TV to connect to the Audio In jack on the Transmitter.
For X1 and X11: You can use the Headphones jack or the Audio Out jacks on your TV (if available) to connect to the headset's analog Audio Input.

NOTE: Please make sure your TV has Audio Out jacks. Some TV's only have Audio In jacks.
Audio In jacks only accept incoming audio signal; they do not send audio signal out. If no audio signal is being sent to the headset, no sound will play from the headset.
___________________________________________________________________
You may need to purchase a suitable adapter cable in order to connect the TV audio output(s) to the Ear Force X-series headset's transmitter or Audio Input plug.
- Connect the HDMI cable so that the Xbox 360 plays its audio through the TV.
- For X1, adjust the Dashboard > Settings > System > Voice in the Xbox 360 so that the talkback and game sounds are played together (Play Through Speakers). - For X3, X31, X4 and X41, you should set this to Play Through Headset.
__________________________________________________________________
XBOX 360 AUDIO PLAYS THROUGH HOME THEATER RECEIVER (except X4 and X41): This is exactly the same as the above, except that you will use the receiver's Headphones output jack to connect to the Audio In on the Ear Force Xbox-compatible headset's Transmitter (X2, X3, X31) or the green Audio Input plug (X1).
- You may need to obtain a shielded audio cable with 1/4" stereo phone plug to 1/8" stereo mini-phone plug ends. The 1/4" phone plug goes to the receiver's Headphones jack, while the 1/8" mini-phone plug goes to the Audio In on the Ear Force Transmit- ter (X2, X3, X31) or Audio Input plug (X1).
- Adjust the Dashboard > Personal Settings in the Xbox 360 so that the talkback and game sounds are played together (Play Through Both). For X3 and X31, you may also set this to Play Through Headset.

Make sure that you have the RC Cables (red and white) plugged into the audio ports that coincides with the component video inputs. If that wont work then try plugging the audio and video cables into the inputs for the satellite, since that works. That way you can isolate the issue. If it still wont work try using the XBOX 360 HDMI cable. That has both audio and video.
