I have an exact similar issue with mine.. I haven’t located the problem source yet.. i’ve tried everything from factory resetting to unscrewing everything and making sure all the wires were in place

Now I am repairing three (3) JBL EON 15 G2 with the same problem again!….look like this a common trouble with these kind of JBL EON. I think the preamp board is the problem but I can’t find a supplier for that assy board replacement part anywhere!!
