Polk DSB1 Sound Bar Bluetooth FOR PARTS ONLY

Polk DSB1 Sound Bar Bluetooth - Condition: FOR PARTS OR NOT WORKING. DOES NOT POWER ON.
(no liquid damage)
Purchased new in 2018.
It was working and suddenly stopped working. It will not power on. I have tried a new Polk power cable.
The issue is some part in the board of the sound bar.
I previously opened the sound bar and looked inside - there are no obvious loose connections. I don't have a multimeter (or proper knowledge) to test any of the internals.
Included in the sale:
