Is my Bluetooth antenna damaged?
My speaker worked perfectly until it rolled and dropped. Now the Bluetooth source must be next to the speaker for sound. Move the source a foot or two away, or place my body between the speaker and source, and the operation acts like a very weak signal. No sound of loose parts.

Thanks to the tutorials on this website I disassembled the speaker to find a wire loose from it's connector on the mother board. After I snapped it back in place the Bluetooth worked well again.
Couldn't have done it without this website. Thank you very much.
