Was at a Shreiber APP6403 today cust has to keep it on fast freeze to get it to run, i was going to order a temp probe and try that 1st, but it is out of stock on masterpart, qualtex and connect, masterpart and connect are showing the pcb as in stock though, its got me wondering if it is more than a good bet that it is the pcb that is causing it, any help would most welcome, JJ
