Default subwoofer amplifier help

Can someone please help me with my Definitive Tech PF15TL? There is no sound but it powers up. Changed the resistor that was blown (19.1 kohms) and STK4050V but still no sound. A schematic was shared in March 2007 and I'm using this as a guide. I'll appreciate all the help. Thanks.

Sure. It was supposed to be a joke based on the fact that, when I first saw the post and when I posted, the schematic was not attached!
I saw that the schematic appeared later but I was too busy to edit my post at that time.

Live long and prosper,
Martin

That 19.1k is for the muting so I would check the muting control circuit. If it isnt supplying enough voltage then the amp will stay in mute mode. See if that mpsa92 controlling it is bad.
