Hey KYStarRider, try not to use up your subscription's character limit on your first post!
Welcome. You had me thinking there but mine worked out of the gate. I didn't disconnect the LCD or remove the gasket I believe. That was a month ago but may as well have been years as I have limited RAM.
I bet you were "on the clock" while fixin your Zumo. Most would just accept that it worked the second time.
