Just an FYI on the resets - not sure about this helping your other problems?
There are two slightly different resets, DCS and conventional. I believe you can do a conventional reset using the Z-750 controller. Conventional reset - 1 whistle and 5 bells with 1/2 second intervals, you hear 2 whistles if works. It might take several tries to get the timing of the whistle and bells just right.
The newer PS3 engines can be DCS factory reset using the DCS Remote Commander. Ps2 and older PS3 engines will need the full DCS system for a DCS factory reset. The DCS factory reset sets the factory defaults for use with the DCS Remote Commander.
Quoted here from an old post by Barry Broskowitz - Starting with the 2014 PS3 RTR sets, in both and HO and O gauge, the set engines should be able to be reset to factory default settings by pushing the following three buttons in this sequence:
SND, DIR, -
