Hi @tim60682,
have you checked that there's 19V DC on the output plug of the power adapter?
Have you tried a different, compatible, known working adapter to see if the speaker charged/turned on OK?
What have you tried?

I did a complete disassembly of my JBL boombox one. I completely removed the battery from its compartment and tested it on a multimeter it showed 7.3 DC volts. Next with the battery still unplugged from the unit I plugged a 20v 4.5 amp aftermarket charger to the outside port I tested the inside PCB plug to the motherboard and it showed 19.5 volts. I have checked for a continuity and all the circuits none are showing bad. It is still a brick pick a number if anybody has any ideas or pointers please I could use that. You conclusion at this point I would say it's either something bad on the motherboard or a software issue / firmware that I cannot update because it will not power on.

@randalljhole what voltage do you get on the battery connector when you plug the charger in?
