Mute works fine and the sound goes off if you turn the volume down to 0. As soon as you turn the volume up to 1 it is very loud, as loud as it should be on the highest setting. All other volume settings, from 1 to 64 sound the exact same. This is for every channel.
Change the audio ic it has a short within.this will restore your set to normal dont forget to make checks in that same circuit as there might be resistors,diodes or caps that had contributed to the failure of the ic.good luck.
