Andy, thanks for the reply,
So no rear speaker hum, black bands on the screen or geometry problems with the PL4?
I can’t decide between to PL4 & the PB50.

I viewed the PB50 again yesterday & the 100Hz is the best I have seen, to be honest if you weren’t looking for it I doubt that you would know it was a 100Hz set, that said I haven't viewed football on it yet. Should be paying another visit this weekend, hope the results are good.
If they are I would be quite happy spending my hard earned on one of these sets…it’s just with my luck I’m bound to get one with all the faults possible.
I don’t mind having the engineer round to get the set adjusted to it’s optimum but if it’s an ongoing problem well that’s a different story.
I suppose I could always buy the PB50 & if it’s loaded with faults that can’t be sorted get it changed for a PL4, best to have a plan.
