I have a 2031530 vision line GS4 that will stop while running under legacy control. None of my other engines do this on the same track. When this happens the headlight starts flashing/flickering. I found that if I touch the handrails the headlight stops flickerinng and I can control it, but it will stop again quickly when I let it run. It also has trouble with Bluetooth.
From what I've been able to read it sounds like the antennas disconnected or the receiver is bad. I can send it back to Lionel but that will probably take a long time.
Where can I find a parts breakdown?
How hard is it to change out the receiver?
