Boot problems

[schumy2001]

I have a problem with a xbox. I installed a alladin advance on a version 5. In the beginning evrything worked fine but now comes the problem. When i boot the xbox in normal mode i get the ms dashboard but when i turn the chip on the screen just is black. You can`t see anything so the box just won`t boot further. What could be the problem?

And the chip you install was reflashed with a BIOS other than the Cornwell crap?
