Recently sold my Bluetooth speaker and it got sent back as faulty. It was working fine before busy have been damaged in transit.

When trying to turn it on the power and Bluetooth buttons flash along with the lights on the top then cut off.

I’ve checked the connections inside and they seem fine. Can you guys give me any tips/indications as to what’s wrong?

Sir Shep . . . . . .
Why shore we cans !
Looking at the two photos, on the right is the one that shows the light brownish phenolic board on the right and a COMPLEX green conformal coated board to the left.
Now as for the "green" circuit board on the left , there is the VEWY-VEWY HIGH pwobability . . . . a la Elmer Fudd . . .of fixin' that board . . . . . . . . . . .
most specifically . . . a rats' anal orfice chance in HADES.
HOWEVER ! . . . now the good thing . . . . . is that if you will look at the right side phenolic board on the close in foregrounds frontal left corner.
There is some major fracturing at that connector with the 7 red wires and most noticeably at the captive phillips screw head.
That unit has been dropped HEAVILY! or footballed !
Pull that board carefully and repair the foil breaks / micro fractures on its other side.
Inspect and scrape off conformal coating to clean copper traces to be able to solder jump openings with liberal use of rosin flux and solder.
Thaaaaassit !

Send good-full close in photos of the other side, if extra consultation is needed,
