Recently, the sound decoder In my n scale siemens charger started to sound a little odd. It sounded like the plastic was vibrating and that the sound decoder was muffled. I took off the bottom covering to see if any debris happened to go inside, and after I did that, the sound decoder stopped working. Is this fixable at home, or is this something that should be sent in and repaired.
I sent an email but I have not gotten a response as of this time
