Indeed it is very informative, thanks for uploading these step details. I had to open up my same xb40 speaker coz it doesn’t start. When I pressed the power button the bluetooth light blinks for 2-3 sec and then it goes off along with the power light. So I showed the motherboard to the bluetooth speaker repair man, he told me the problem is with bluetooth chip without checking the circuit board. Can you further guide me on this please, where should i find the new motherboard, I live in India.
