Your very welcome and glad you got it working . As mentioned if it's dirt / bad contact that fault could happen again, then you need clean out with electronics cleaner.
Also if your wondering why I'm on here so late, I'm actually software engineer, and I sometimes work late programming with the OCUK forum open. But again i'm glad we managed to solve this issue .
