I had a similar experience with my digital clock too. For some reason it fell
in love with the #6 and wouldn't change off that. Except for the occasional
16 that would show up. And then one day I was checking out something in the
instrument cluster and low and behold the clock was on the right time
again.........hmmmm. Kinda strange and cool at the same time.
Take care,
