TV/Xbox Slim issues

[Kasabian]

Some of you may, or may not have known I managed to 'accidentally break' my TV. Anyway.

I use to use my Xbox slim on that TV just fine, using a HDMI cable.
My new TV came yesterday, and the picture will not display when attached via the HDMI cable - yet the composite cables work just fine.

If you've ever compared SD to HD gaming, you will feel like your eyes are bleeding.

Now, It sounds stupid, but does anyone know what I can do?
The HDMI cable works fine on my SKY+ box and my surround sound, but not my xbox.
The xbox works fine on other tv's.

Cheers.

Does anything show up at all when the HDMi is plugging in and the Xbox on? Can you hear the sound at all? And are you sure you're on the correct HDMI with there being two. Silly things I know but easily overlooked.

No input at all from the HDMI, and yeah i've plugged it into both ports and tryed both sources.

I can't remember without looking but does the Xbox have in the settings the frequency setting? Like Auto, 50Hz, 60Hz. Is it set to either Auto or 60Hz?

Xbox doesn't give auto option, but I tried it on both 50 and 60Hz.
I'm gonna pick up a component > HD cable tonight, should work.
