Spoke too soon. I noticed after 20 min. or so warmup, the right side was
slightly in about a quarter inch, fluctuating with scene brightness
changes,like a HV regulation problem,and my HOT was getting hot to
touch.
There still is an issue here.Another tech thinks maybe I have a bad scan
cap.Seems time related.
Back to the drawing board.
With 169's dozens of things could be a culprit.
