Xbox sound but no picture

How is your xbox connected to the tv? If its connected with hdmi cable. Unhook it from xbox and plug it into the back of the cable box. If nothing happens then try switching the tv input with the tv remote. Should have several different inputs. Hdmi,video,component,etc...

Your problem is in the TV. I'm not familiar with your TV, but you should look for an option to turn it to normal or to try and scan for channels with xbox plugged in and running. I'm pretty sure that if you get HDMI cable, your problem should be solved.

check the audio cables

Beats me and i repair xbox360s on a daily, try the composite, component then try another HDMI cable, yours might have a broken cable within it...hope this helps....

Is this the first time you've tried plugging in your Xbox?

Is it Xbox or Xbox 360?

Try plugging it into another TV yet?

I've had a similar problem where I've manually set the resolution of my television on my Xbox. I had it set up for 1080p and then plugged it into my little CRT. The picture was all scrambled and I couldn't do anything. I had to plug it into another TV to fix it. This is the original Xbox by the way.

Check the settings on the Xbox, and if that doesn't work, try swapping out the cables or put it on another TV.

What kind of television is it?
What type of connection are u using?
Have you tried the XBox with another set?
to make sure its not the xBox.

You bought a new Xbox ,same problem.
Plug the unit in to another tv . Replace the
a/v cable , if still no picture then take it back
and get replacement.

If you've just bought your xbox 360, then you probably haven't got a HDMI cable.

Which I think you could need.

hi MC, power off unit unplug av cable from back of xbox.. then power up unit.. after a couple minutes the xbox will shut down.. plug the av cable back in and power up.. Good Luck

Are you using the component video cables? If so, make sure each is plugged into the right port. It is possible one of the two speaker cables is swapped with the video.

If that's not the problem, it's also possible you have a short in your video cable. That seems more likely than a problem with the Xbox itself. Try connecting it to the TV with a new video cable and let me know if that fixes it.
