I have a TMCC Command base with the following:
- post on command base is hooked to U side of transformer & original 12VAC power supply is connected
- green power indicator is lit
- red signal indicator flickers as expected when cab 1
- when power is applied to rails, locos start in conventional - apparently no tmcc signal is present
- crystal has been removed/reinserted (leads are clean)
- opened unit and no obvious failed components on board and all solder joints appears intact
Thoughts? Troubleshooting options?
