Sony HT-A5000 No-Sound Fix

My Sony HT-A5000 sound bar powers up and responds to the remote, yet there is absolutely no audio on any input—HDMI eARC, optical, or Bluetooth. Cables, TV settings, and source devices have all been ruled out, so the fault is clearly inside the bar itself. I need an experienced audio-electronics technician to: • Pinpoint the component or board responsible for the loss of output (amp stage, DSP, power rail, etc.). • Advise on parts, firmware, or board-level repairs—and, if practical, carry out the work once I ship the unit or module to you. • Verify the fix with a quick video or live call showing sound restored at normal volume on at least two inputs. Please confirm familiarity with Sony service manuals and typical tools for this level of repair (multimeter, signal generator, oscilloscope, hot-air rework station). Turnaround time and any parts lead-time estimate will help me schedule shipping.
