What if there is no sound in the stereo?

Check whether the two audio sources are normal first. If there is no signal in one channel, it means that it is a hardware failure, and you need to contact the after-sales department for detailed inspection and maintenance.

Component problem

Change the components on the sound side to the position on the silent side and remove the components on the silent side. If there is a sound, it means there is something wrong with the component, and then it is easy to solve the problem.

Circuit board problem

If there is still no sound, check the connection problems of the circuit board, such as virtual welding and open circuit.

Symmetrical treatment

Generally speaking, the power amplifier handles the left and right channels symmetrically, that is, the circuit principle, component model and component number are exactly the same.

correlation method

Therefore, it is easier to find problems through comparison.
