Thanks Ron, I re-worked a few solder joints and was able to bring things to life. Performed alignment and places in case, but now have a couple of other issues to troubleshoot. 1) on power-up, LCD looks normal but text slowly dims to nothing and no functions work. Power-cycling right away brings up LCD with no text and no function. Waiting a few minutes to power-cycle brings up LCD with text which then dies away as before. 2) I performed a factory reset to see if that would help but now on power-up I have a LCD that is not lit but has text 'use original ic' and no functions work. I can see this is going to be a journey!
