I have a djx700 mixer which when switched on works perfectly for about 5 minutes before there is a loud pop and then all channels are full of noise (sounds a lot like a grounding issue). i'm guessing that there is some vital component (not sure what) that is overheating and causing the noise. I would be very greatful if anyone has experienced a similar problem and might know what is causing the problem becasue then i'm guessing that it would be possible to replace the component. cheers
Sounds like an electrolytic capacitor that has faulty electrolyte. Look for the culprit in the power supply area. It looks like a can covered in usually light or dark blue plastic. It's end may have developed a 'bulge.' This usually occurs with capacitors around 10 years of age or heavily used over a long duration, or under very hot conditions.
You may also want to make sure all solder joints in the power supply are good.

i have a djx700 mixer which when switched on works perfectly for about 20 seconds before there is a loud pop and then all channels are full of noise (sounds a lot like a grounding issue). Ive have read the suggestion to look at the capacitors and check for a bulge in the end of them but there is no sign is there any other way of checking the capacitor is working correctly? cheers
I have the exact same issue as the mixer works for about 10 minutes then I get this high pitched squelch noise.
I gave up and bought an Allen Heath mixer but want to keep the Berhringer as a back up.
I'll try solution 1 but if anyone has more info please help.!!
