No sound coming from amp

The amp Powers up but I get no sound when I hook up speakers. I've tried several speakers. So it's definitely something to do with the amp. Blown channel? Can it be fixed and if so around how much for the repair?

这是一个好问题吗？

Hi @cheddarbob ,

Have you checked the signal source to prove that there is something going into the amp?

The output FETS could be blown. You need to bust out an O-Scope to see if you are getting gate drive from the driver IC. These amps are like $80 used so you may have a hard time finding a tech to fix it for less than $100. Good luck!
