Hi Stewedg,
Have you had any luck with your rear screen?
I have exactly the same problem, only 2 thirds of mine works. Unfortuanately the bit that doesnt work is in the middle.
I guess its a faulty connection somewhere in the element and so far have not looked. Any advice would be much appciated....especialy with the weather we've been having over the last few weeks.
