Got a Jbl prx712 power up NOTHING CONNECTED only power cord (yes I’ve tried different outlets and also a fused powered plug strip) volume on both channels is turned all the way down yet there is white noise as if the volume was fully cranked after a few seconds from the Tweeter you hear a super loud popping that sounds like noise any ideas? What should I check or look for? I looked around at the board transistors, etc. nothing looks out of place corroded worn or damaged.
