I have a Lionel N&W C420 (item number 6-28244 that ran fine for a short time but then the sounds went away. I did the factory reset but no improvement. I checked the volume control and after turning it five or six times, I heard some of the sounds come back but if I moved the shell, the sound would become intermittent as though there was a short or a bad pot. I then tried to take the shell off (a really tight fit) and an aluminum metal plate about 1/2 inch wide by apx 1 1/2 long with a connector on one end at 90 degrees managed to get stuck between the base (catwalk) and the sides of the engine. After a great deal of working with it, I managed to dislocate the metal plate from what ever was holing it and remove the shell. In the process, it appears the metal shield around the coil on a board marked "SDK4205" was disturbed. I then tried to run the engine but it tripped the breaker and I notice the board got that burnt electronics aroma. I removed the SDK4502 board and the engine ran OK but no sounds.
My questions are:
Does any one have a photo of what the insides of the locomotive should look like as the shell is to be replaced?
Where does the metal plate go?
My guess is I need a new SDK4205 board. Do you agree and if so, where do I find one?
Am I on the right track or should I be looking for something else?
Appreciate any help.
Thanks,
Don
