Messiah 2 blank screen

[masterslugs]

Hi,

I noticed in another topic about this problem, not too much on how to fix tho.

I installed my messiah, it all went in fine apart from the cpu wires, which were a pain in the ass to get the soldier to stick.

Install is complete, ps2 didnt "blowup" upon pluggin into the wall. But all I get is a black screen, no sound.
Pressin reset flickers the screen?

Thanks
