dennis hoff , Probably a shorted audio amp IC(capacitor), the 1st link below discusses the issue. The 2nd link you may perhaps be able to get your service manual if not try a search using your make,model#. If not wanting to do the repair your self or if under warranty have a good local TV repair shop have a look and estimate repair. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
