Problem: Sound does not come out from one speaker One of my customers sent to me his computer speakers with the complaint of no sound in one side. I tested the computer speaker and indeed the left speaker does not produce any sound. The troubleshooting begins by comparing (sight) the components between the right and the left channel. All of the components seem to be in good condition.

This led me to check the components in the left speaker circuitry. By the way both speakers rated at 4 Ohms checked to be good also. Note: The above schematic diagram does not reflect the true circuitry found in the computer speakers. It is just for your reference purpose.

When I placed my meter probe between point A and ground (above schematic) the meter buzzer sound indicated short circuit. It can be shorted components or the IC. I removed all the corresponding components and found that the short circuit was still present. I then removed pin 2 of the IC and the short circuit gone and the buzzer was silent. When I soldered back pin 2 and powered On the IC, it was quite hot. I should have test the IC first with my finger.
