Thanks Moscow Wolf, it all makes sense in theory so if we get any visitors who are handy with electronics I will rope them in, (I know my son could sort it if we had the pleasure of his company) I think Jack could probably do it when he eventually joins the land of the living, he is good with electrics but not so good with computers or new technology.
I am definately not going to unplug anything as I only have to look at a machine for it to go kaput. I will let sleeping dogs lie for the time being, just glad we got the darn thing working. Have a Happy New Year M.W. you too Nikki and all you other lovely people. Pat
