I don't know what to do... I bought a mixer for a small church that I was upgrading the sound system for. After a couple of uses the mixer got so hot that members started to see smoke from the mixer. Everything was unplugged and it hasn't been used since. Its going on the second week since putting in a care ticket and I don't even know if they have seen the ticket. This will have to be the second Sunday of not being able to use the sound system. Why can't someone help me?
