I have managed to lose my sound and lights on 2 of these units. All of my other sound locos including a couple other MTH SD70ACE's are running fine. These 2 w/o sound/lights run fine otherwise. I did a reset F28 also for sound F21 and master volume F6 per the MTH instructions. All on my DT402D. Have I not entered the right Functions on my throttle or am I not doing the functions on my DT402D right. Haven't had this happen before. Thanks.
Sometimes I forget there is no sound on MTH's until F3 is actuated, altho they will move.

Thank you very much Hal. Boy, I was sure overlooking that. Have to remember acutuating F3. Thanks again.
