F-3 Santa Fe Black/Silver

[M1FredQ]

A strange problem has developed with this engine.

When it is first turned on after sitting idle all night., the sound system works. Afterwards not at all.
Even after I turn it off and let it sit off track for awhile.

Does anyone have any ideas or should I send it back along with the other engine Bachmann asked me to return?

I would send them while they are still covered by warranty.The sooner the better.

They went UPS both the F-3 and the GS-4.

I'll post what happens when I get them back

Thanks for everyone's help
