thanks for all the suggestions. I'm leaning towards a connector but haven't had the chance to look. I recall my TZ resetting and that was a connector, now just got to figure out which one it was. I also think I installed the Rottendog driver board as it wouldn't work with my T2. So bad components by rights shouldn't be the case although not totally out of the question.
will update if I'm still no closer to the cause. thanks
