This is a followup video of my previous TDA7491P fix, can be seen here:    • TDA7492P Bluetooth amplifier loose solder ...  

Now by accident I have connected the power with wrong polarity, and even tho the on-board power switch was NOT TURNED ON, two parts were burned in the circuit.
As the board was already totaled, we have nothing to loose. So we have grabbed the camera, and tried it again for you.
(The right polarity for the DC plug is center positive.)

Since this I have bought another one. See the review:    • Tested and modified the TDA7492P Bluetooth...
