blue screen

[sl1m]

Hi fellas,i have a question to ask;

I have burned an iso of TOEJAM and EARL III with PrimoDVD.

I have a tv wich screen turns blue when theres no input signal.

Now when i boot my xbox with the backup,i see the xbox opening scene,but when its gonna load the game my screen turns blue,although i can hear my xbox loading the intro movies and stuff like that.It never happened before,so i am quitte curious of what happends here.

If any1 nows,please share the knowledge.

Thanks in advance
