Several years ago I installed EOB in 3 of my TMCC engines. Over time all have failed with the same symptoms so I'll concentrate on one engine. A Lionel SD40-2 (6-28524). It originally was factory TMCC with Odyssey speed control. EOB installation went smoothly and the engine performed flawlessly for years. Now as soon as apply track power railsounds come on and ramp up thru the three cycles. With the Program/Run switch in Run I can't address the engine with the Cab 2, I have no control of engine. When placed on my conventional layout I get the same symptoms, railsounds come on and engine won't move. In the program position railsounds come on and I can't program the engine. The wheels turn freely. Checked the antenna connection and it is solid. Replaced radio receiver with an new R2LC board and a new R4LC 08 board. No change with either board. No broken wires or burnt components. All boards reseated and all connectors plugged in. The lights come on, no control of the couplers. Don't know how to proceed, grateful for any help.
