Xbox Paper weight???

[Berzy]

I just installed a x2 lite mod on a buddies v1.0 xbox. nice clean sodder job, actually better than i did on my own.

but when i boot it up on the led i get a solid green, then for green & red blinking with nothing showing on the tv.

question is do i have my buddies xbox fubared or is this fixable.
any help here folks since it's not my xbox i feel like an ass.

thanks
