I installed an PT-AX100U in a community center a few yrs ago. They called me because it is now powering down after 5 minutes and/or sometimes won't power up unless the unit is switched off at the back and switched on again. I've cleaned the filters regularly etc...does this sound familiar to anyone ?? Thanks

Yep! The iris is failing. Search for "PTAX100 problem" (might have a dash in the beginning or a U at the end of the model#) and you'll find a whole thread dedicated to this issue...

Thanks a ton. After reading through that thread it sounds like my problem is that famous "iris issue".
