[QUOTE="jasongoldworthy, post: 1889697, member: 395464"] hi Steve thanks for the reply and yeah I've bypassed the power switch and still no go. I'm getting 12 volt well almost 12 volt which I would say is ok its at 11.7v on all pins as I'm not getting any diagnostic led's to say there is standby voltage id assume the logic board is dead ?? although when I cracked her open there was no dust in there at all so id say she was barely used. as I said the only history I have was that it was on one day and just turned off and never came back to life after that but many thanks for the reply Jason.
