Hey guys,
I have a strange problem here. I just bought a damaged DJM 800 mixer with intentions of fixing it yet it seems to be a little more difficult to fix than I initially thought. I was wondering if you guys could help me out a little bit. The overall problem is that the board is getting no audio input signal anywhere. It powers up and functions just fine other than that. All faders and knobs work as well. I tested in all four channels and I'm getting no levels on any of them. I also tested a microphone and got no levels through that either. I have a feeling one of the cards isn't receiving signal and passing it to the board. I just have to figure out where that problem is.
I was hoping someone would be able to help me trace the signal as I don't really know how to do that. I'm eager to learn all of this so I think this is a good project for me. If someone could point me on the right track as to how I should go about finding the problem that would be awesome. Also, I have the exploded views and other information on all the electronic aspects of the board I'm just not exactly sure how to read and utilize the information. I'll try to attach that to this post. I also have the service manual for the unit but it is too large to attach. I can send that to someone if needed. Thanks a lot guys.
