I'm servicing a Canton AS 80 SC powered subwoofer. I replaced the power output IC and it worked for a few minutes but the next time I powered it on, the output was next to nothing. I found the datasheet for the TDA7294S here.
I am trying to determine if the muting is activated by a high or a low input on pin 10. I'm guessing that a high input mutes the audio but I'd like other opinions.
Thanks for your reply.
