Small audio subwoofer failure:

A, small audio subwoofer inside the transformer is not bad

Indicator light does not light! No power supply feeling!!! Thought it was a bad transformer! Small built-in transformer! Input 220V output 10.8V1.5A two blue a black! I use a multimeter to measure the output of blue and black is the same! Is the transformer burned? Tested with an external 6V power supply connected to the circuit board of the blue and black when the stereo response indicator light on!

I just want to ask my transformer is not bad? How to make sure he is bad! Where can I buy such a transformer! Can I use another external 12V transformer instead? His output is 2 blue and 2 black!

First of all, you say so, you use the resistance gear to measure the through, this is normal, if it is not bad, you now so, unplug the transformer all the load end of the wire, plug the transformer, with the AC gear to measure the transformer output there is no voltage can be. No voltage must be bad.

Two, the subwoofer sound, two small stereo no sound causes

Subwoofer sound, two small speakers no sound causes:

1. Operation problems: two small speakers audio plug is not inserted into the output jack but into the input jack, resulting in small speakers have no sound, while the subwoofer has sound. This kind of speakers, the input source can be in the front or in the back, in front of the 3.5 stereo jack, while the back is a lotus jack.

And the input and output are side by side design, so, when connecting the small speakers must be clear, you must insert the two plugs of the small speakers into the output jacks, this output jack refers to the amplifier's audio output to the speaker's jack.

2. Circuit problems: bass speaker and two small speakers on the circuit board with two integrated chips, it is possible that the small speaker power chip damage caused by two small speakers at the same time does not sound.

3. Line problem: when the two small speakers of the connecting wire, plug or two output jacks at the same time, will also lead to two small speakers at the same time no sound.

4. unit problem: when the two small speakers speaker unit is damaged at the same time will also appear two small speakers at the same time the phenomenon of no sound.

5. Adjustment problems: when the volume of the small speakers and bass speakers is controlled by two potentiometers, which adjust the small speakers of the potentiometer is not open or damaged may lead to the small speakers without sound.

6. False connection problem: when the two small speakers are connected to the crimp terminal type, at this time, if the wire is thin crimping is not firm, crimping spring power will lead to audio line false connection phenomenon, resulting in small speakers without sound.
