Hi guys
My problem is this, when the thing is running on battery the screen is bright, but when I plug in the mains lead the screen dims. It used to be the other way about. It is NOT the power lead, as I have tried both a repaired unit and a brand new one.
Anyone help?
Andy

Perhaps something in the following might help:
