Hi All, I have an Athearn N Scale Challenger 3977 with ESU Locksound Decoder that has lost all sound or at least the sound is at such a low level to be barely dectectable. I *think* I can barely hear the whistle bu that is it. I have tried toggling the "mute" function. I use this with a Digitrax System. I have tried everything to try to reset the decoder to factory Default. These include: Programming CV 8 to 8 in Ops mode. It says "Good" but does not appear to reset even when removed from the track and replaced on the track. The locomotive still responds to the programmed address of 3977 after this is done. When i try to read any CV in ops move I get a Fail message. Tried Programming CV 8 to 8 in Pg mode on the Programing Track - no ack Tried Programming CV 8 to 8 in Pd mode on the Programing Track - no ack Any suggestions outside of sending the locomotive to a shop to have a better decoder installed? thanks, this is a bit of coal in my stocking.
Correction! This loco has a Tsunami decoder instead of a ESU. If someone could edit the title to reflect that I would greatly appreciate it!
