Why is my Sony stereo receiver not working?

By Jessica Cortez

Why is my Sony stereo receiver not working?

These directly drive the loudspeaker outputs on the receiver itself, and one or more of them being shorted (closed circuit), will trigger the error on the display of the receiver, and it will not go off until the problem is repaired. They are not user-replaceable as they are PCB mounted, and thermally coupled to a heatsink.

What to do when your stereo won’t turn on?

If it still won’t turn on, try a different wall outlet. Make sure that your device is set to the correct voltage for your area. Some devices have a 110 to 220 voltage switch where the default setting is 220V. Verify that this switch is set to 110V. Press and hold the POWER button, and unplug it from the wall outlet at the same time.

What should I do if my AV receiver turns itself off?

Replace it with a new fuse of the same amperage and voltage (available from electronics parts stores such as RadioShack for about 50 cents a pop) and you should be back in business. If, after your fix, the receiver powers on, but then turns itself off after a few minutes, it’s possible something is physically damaged inside.

Is it possible that my AV receiver is toast?

A: It’s possible that your receiver is toast, but don’t give up hope yet. There are two things to check. Many modern receivers have “protection circuits,” bits of specialized hardware that recognize dangerous levels of volume and shut your hardware down, like a digital fuse. Some receivers communicate this on the display.

What causes a receiver to have no power?

The cause of no power will have to be proven by diagnosing the problem using the correct equipment and fault finding techniques. If you do not know what you are doing, it is extremely dangerous to remove the cover and check inside the unit. There are lethal voltages present.
