I've had a lingering problem on my BTTF machine where the settings won't stick (free play and attract music off.) When I change the settings, it confirms that it was installed. But as soon as I step forward or backwards to the previous setting and then go back to the one I just changed, the setting is back at the default and my change didn't stick.

I first checked the batteries and confirmed voltage. All good. Just for the heck of it, I removed the batteries and popped in a NVRAM chip. Exact same issue. So although it shows that the change was installed, it just wont' stick. Anybody see this on any other DE machines?

Note..I know just enough to be dangerous and am new to the forum.
thanks!
