No picture on TV when Xbox 360 is turned on

Most likely a damaged AV output socket , possibly lifting of the solder joins,

try it in another tv with av cable
if u are using hdmi cable try changing the existing cable

if it works in another tv , go changing the setting in the displaysettings and video settiing

Follow the steps below, Hope this helps

1. Try another Av cable ( Audio video Cable )

2. Try another television

3. If the steps dont work, call xbox customer support to have your xbox serviced. Good Luck! hope your console still has warranty

The main reason why its acting that way its possible that the AV PORT is faulty or its your cables..

You might want to try the following:

1. make sure that the AV cable is not loose or incorrectly seated in both the Xbox 360 console and the TV
2. make sure that you have the correct AV cable for your TV, to verify that the AV cable is connected correctly to the Xbox 360 console and to the TV, disconnect the AV cable and then reconnect the AV cable to both devices
3. if you are using composite cables, do not try to set any HDTV settings because you may lose the picture
4. make sure that your TV is set to the same video broadcast system as your Xbox 360 console (PAL or NTSC)
Example:
- if your Xbox 360 console is an NTSC console, make sure that your TV supports NTSC
- if your Xbox 360 console is a PAL console, set your PAL settings to PAL 60
- if your TV has a type of picture compensation enabled, disable it
5. reset your Xbox 360 console
- Remove any discs from the disc tray
- Turn off the console
- Turn on the console
- As the console starts, press and hold the Y button, and then pull the right trigger at the same time
- The Xbox Dashboard resets the display settings to the default settings and then automatically restarts the console.
6. Do not take your Xbox 360 console or its accessories to your retailer for repair or for service unless an Xbox Customer Support representative asks you to do this

What do you mean, no display? Is is game-related display issues? Have you checked the AV cable connection? Or is it about the settings? Is this the first time that you are going to connect your xbox console?

To determine whether the display issues are specific to a particular game, try playing a different game to see whether the same symptom occurs. Reminder, some Xbox original games that were released for the original Xbox console may show some display issues when you play them on the Xbox 360 console.

Next, make sure that AV cable is connected correctly to the Xbox 360 console and to the TV. To verify that the AV cable is connected correctly to the Xbox 360 console and to the TV, you can disconnect the AV cable and then reconnect the AV cable to both devices. Note: If you are using composite cables, do not try to set any HDTV settings. If you try to set HDTV settings, you may lose the picture.

You might also want to check your TV's settings because some display issues can be caused by how the TV is set up. To make sure that this is not the case, please check your TV's settings.

In your TV's settings, you should check the following:
- Make sure that your TV is set to the same video broadcast system as your Xbox 360 console (PAL or NTSC)
- If your Xbox 360 console is a PAL console, set your PAL settings to PAL 60
- If your TV has a type of picture compensation enabled, disable it
- If your TV's settings are correct, you may want to try using a different TV, if you have one available. Try connecting your Xbox 360 console to another TV to see whether the same display issues occur

Next, reset your Xbox 360 console. To reset the display settings to the default settings, follow these steps:
1. Remove any discs from the disc tray.
2. Turn off the console.
3. Turn on the console.
4. As the console starts, press and hold the Y button, and then pull the right trigger at the same time.

Here's one possiblility.

There should be a switch on the x box cable that goes from High definition output to analog.

Try changing the swith setting.

where you put the cables for the sound and picture if you look on the end where you plug it into the xbox 360 you will see a little switch it has HD and TV on it depending on what your tv supports (HD ready TV) (normal TV) switch that switch to what TV you have (e.g. HD TV, switch the switch to HD) if that doesnt work then try checking that you have all the cables in the right ports if you have pluged the HD cables into a normal TV then this is not going to work, check cables and check the switch!

I would try some of these troubleshooting steps;

1. Make sure that the AV cables are 100% secure.
2. Try an new AV cable.
3. Try your console on a different TV.
4. Call xbox customer support at 18004MYXBOX

I have it and it works great! For all TVs, the TV have to be on fixed settings on standard, dot-by-dot mapping, noise reduction off. The camera's exposure the same for both side-by-side shots. Just set it on standard and it should work...
