Hey guys - just did an install on a version 1.0 xbox - installed the executer 2.2 pro - no worries on first turn on did everything it was supposed to, my brother flicked off the xbox now we have a no go. - just blue screen.

Upon this i checked the soldering etc.. make sure nothing is loose.

Everything is A ok, but still no pics or sound or anything for that matter - what could be wrong. Itr does bott up normally if i disable the chip and the light stays on green solid - Any help???

It sounds like you have solder bridging some traces on the LPC. Something is wrong there. If D0 was right and the LPC was functioning you would get a frag (LPC not soldered correctly) or cromwell (LPC soldered correctly and the chip loading the bios. If you aren't getting anything there is an issue on the LPC that is keeping it from functioning - clean up the solder. By the way, you need RCA cables only for cromwell no S video or component (RCA came with the xbox).
