What to do when left speaker wont turn on?
Swap the left and right cables between the preamp and the power amp, i.e. connect the left preamp output to the right power amp input, and the right preamp output to the left power amp input. If the right speaker starts working, and the left speaker quits, you have proven that there is no output from the preamp’s right channel.
Why is my amp NOT working with my speakers?
If your amp turns on but no sound comes out of the speakers, your overall setup may be the problem. Not all speakers are compatible with an amp. If your amp is still alive, it will respond when you connect it to speakers and other devices in good condition. Turn up the volume to see if anything changes.
Is there a way to fix an amplifier with no sound?
After spending some times to check the circuit board, I can’t believe that there were actually 15 bad components found which include the burnt resistor. After the replacement with new components the stereo power amplifier with no sound problem was finally fixed. I did not post the video thus you would not hear the sound but the sound worked!
What causes a speaker to go out in my house?
For example, your system might have a tuner, a preamplifier, and a power amplifier. The signal comes from the tuner, passes through the preamp, passes through the power amplifier, and goes to the speakers. A problem in any of the components along this chain could cause a speaker to go out.

Why is there no sound output from one of my speakers?
There is no sound output from one of the speakers. I changed the ports and checked but its the same story. The speakers are fine. Seems like only one channel is working on A or B (Left). Where do you think the problem lies? If you take the cover off the unit you might find fuses inside that have blown.
Why is my left speaker not working on my Sansui amplifier?
Case details: The left speaker works fine. A loose connection in the amplifier, an incorrect balance setting or a damaged speaker can likely cause this issue. First, power off the speakers and switch between the left and right connections on the amplifier.
How can I tell if my amplifier is not working?
Usually the first thing I do was to connect a speaker at the output jack to see if the sound really not present. Another test is to check the output DC voltage at the speaker output jack. It should not have DC voltage and from the test I got 35.6 DC volt which mean the internal power transistor had already shorted.
