John - any help is much appreciated... tearing my hair out...post
when you have time...

Peter - many thx for your help - I would like to try the things you
suggested but I'm really not experienced at all in electronics and
have never opened up stuff myself... and yes - I was expecting it to
be a return to STS repair job and me just pay for shipping kind of
deal.

I'm sure the tech checked the PSU voltage, etc - (he initially
suggested a beefed up supply might cure the problems as my Panels are
fairly stacked but the problems were still present when I disconnected
Panel's 2 & 3 so it can't be overloading the PSU).
