Have you tried hooking your xbox to another TV?

Hello

The Xbox 360 connects to a TV using either

- COMPONENT (red blue green for video, red and white for audio

- COMPOSITE (yellow for video, red and white for audio)

- HDMI

So, if your TV is on a "Channel", it is not on the correct input to view the Xbox 360.

Check the Xbox and verify which cables it is using to connect to the TV. When you find this, follow the cable to the back of the TV and find the input selection. It should be listed as the type and a number (i.e. HDMI 2, COMPONENT 1).

Have the Xbox on. Use the TV remote and use either the INPUT or the MENU options to change the input to the input that matches the port that the Xbox is connected to.

This should make the Xbox work.

When you are done with the Xbox, use the INPUT or MENU to change back to the tuner to watch TV.

check your red,yellow and white calbes and check if they're in the right slot or check if your on the right video where your xbox is playing from

It's a problem with the GPU. You should contact Microsoft for support.

the G.P.U has more than likely detached from the main board.
the x clamp mod is more of a diagnostic procedures than an
actual repair function. The G.P.U will need to be re-flowed to
the main board then lightly but firmly clamp to the board
then stress tested (force it to run hot for 15 min shut off and
repeat 3 times)

that's it

alright. make sure that your red, green and blue are all plugged in properly and that your audio plugs are also in there correct plugs. i think audio is red and yellow. correct me if im mistaken

Is the TV an High Definition TV?
If it's not an HDMI compatible tv them you will need a regular audio video cable for your XBOX 360
you cn get them all day on ebay or at any store.

it may be your tv, not your 360, check connections, or fix geometric settings (if you live near a fault, or if you have your tv on top a mini fridge.)

Might be a faulty power supply mate , when you turn the xbox on observe the power indicator on the power brick.
Green means its okay
Amber means the console is in standby
Red means the Brick has had it.

Try a friends power brick to see if it does the same.

Make sure you are using the correct video settings. Try using the basic red white yellow cords and see if that helps. Also make sure you have switched between HD and regular video. there is a switch on the video cable connector that plugs into the xbox.
