I’ve been having a problem with a American DJ v1000 a customer brought to me. It started out that someone had spilled a drink on it and it kept blowing the inline breaker. After some checking I found a few bad transistors & other components on the main board so I replaced the main board. Now it don’t cut out but all I’m getting is a load hum, I put it on the scope and I’m getting a weird output signal. I have a good wave at the transistors but coming off the transformer and a few different other areas like the ic chip I’m getting a few different waves and non look good. I’m thinking it’s the transformer, I replaced the chip with no effect. Any one ever come across this before and have any advice.
Thanks
Tony
