Thanks to all the great information and replies. I need to get time to get to the bench, but have a wave of issues hitting our family right now and just when I think I can catch a breathe, we get hit again.
But I digress.. I will try the resets.. but let me ask this.. since I am not as well versed in modern Lionel electronics, what options would I have to restore TMCC AND Conventional operations? Thanks again and I hope to have positive results soon
