Some Xbox 360 games, such as Dead or Alive 4 or The Outfit, simply won't start, although your console is in perfect working condition, the disc(s) is/are not scratched, and your TV is working well too. However, some TV sets won't support the video output of the console. That's why this behavior occurs when you try to play an Xbox 360 game while the console is set to PAL 50 Hz.

For Standard definition TVs

To set your Xbox 360 console to PAL 60 Hz, follow these steps:
Turn on the Xbox 360 console.
In the Xbox Dashboard, select System, and then press the A button.
Select Console Settings, and then press the A button.
Select Display, and then press the A button.
Select PAL settings, and then press the A button.
Select PAL-60, and then press the A button.
When you are prompted to keep these new settings, confirm the settings, and then press the A button.

Note: Some older TVs do not support PAL 60 Hz. If you are not sure whether your TV supports PAL 60 Hz, contact the manufacturer of your TV.

Just like current generation consoles, a console designed for North America (NTSC) won't work on Europe (PAL) for the simple reason that games are region locked. So if you get an US Xbox 360, you'll have to purchase NTSC games because those titles sold in Europe won't work on your North American Xbox 360.
