Hi Paul, in this one the wiring is almost never the fault. This one will need a new main control board (console board).
Its easy to replace, no soldering required and I will help if you need me then as well.
The best place to get a new main control board is: http://www.espares.co.uk/
I would call them to place this order for a few reasons, one) there are so many different ones let them pick that for you so you are sure to get the right one the first time ;-)
Also they will ship the same day in most cases when you call.
And they are very reliable.
Please call Espares: 0844 9777 888
In any case, I will stick with you until this is complete.
