I have basically the same problem with my Cab-2 as Fredstrains described a handful of topics down. The right hand red LED continuously blinks rapidly, and the speed bar sweeps to full throttle. If I power off and on it stops, but resumes within a few seconds or immediately if I push any button. So it sounds like a communication malfunction that requires the remote to be shipped to Lionel for service? I didn't try changing the Cab-2's channel, but that probably isn't going to be a fix. This is my second Cab-2 which I purchased in 2015. Didn't last long! The previous lasted nine years until my grandson dropped the remote. Poor guy felt bad, and I felt bad he felt bad! Can anyone tell me a ballpark for this type of repair? I know it depends on what part or how much repair time they will put into it, but I may need time to save if a costly repair.
