This doesn't sound like a rom issue... but rather something else hardware related. If I were you, take it to the nearest $print store and see if there is some kind of warranty you can claim. I would not tell them that you have rooted the phone at all... if there were anyway to reroot the phone prior to taking it in I would do that, but seeing as you say the phone is now in a power off condition it's likely that if the techs cant get it to power on as well they will just replace it
