Sorry for the late reply on this one guys, it was a project on the back burner. The screen was good and turned out to be the metering. i did bend it out a ittle when i stripped it down(it doesn't take much to throw out the metering as they are tiny). After a lot of tinkering and adjustments in small increments i got it right so all good now. Thanks for the help and advice. Feel free to close this thread.
