Other than the MUTE, there are no other features/functions that would completely disable the sound output. Even ATT -20dB would only reduce the sound but there would still be something audible.If all wirings / external factors / settings have been ruled out, then it would only point to an internal hardware issue.Are you then considering a DIY (do-it-yourself) repair approach? Are you familiar with electronic components, have access to / comfortable in the use of a multimeter and perhaps even a soldering iron/hot-air station? Please post back how you would want to approach this and/or should you need additional information.
