Wondered if you can help. I’m a novice to digital music, having spent most of my life with Vinyl and pioneer mixers. I recently bought a second hand x1800 prime mixer. Had it for a few months no problems, until today. I turn on the mixer and it boots up(lights flash and go though it’s sequence) then it stays on for 20 seconds, there’s a small click sound then it turns off and the back on again. Just keeps going round and round turning itself on and off. Any ideas?
