Stereo receivers are produced by a number of different companies with countless different brands, ranging from expensive top-of-the-line models to simple dilettante types with a minimum of extra features. Each model has its own particular design, and its own particular methods for correcting problems when they arise. Certain basic issues are common to all types of stereo receivers, however. You can address them with a few basic troubleshooting steps before calling a repairman or buying a replacement.
Instructions
1. Check the connections in the back of the receiver and the cables that link it to the speakers, the radio antenna and other components like a TV or a VCR. The cables need to be securely fastened on both ends of the connection and plugged into the correct outlet ports. If the cables or outlet ports are dirty, that may be interfering with the sound. Clean them using a cloth or paper towel moistened with rubbing alcohol.
2. Examine the buttons on the front of the receiver to make sure that they are set to the correct component. Stereo receivers can switch the signal from different input jacks, allowing you to play CDs, watch television, listen to the radio or view a movie on DVD all from the same centralized control station. If you are not receiving sound from the component you want to use, push the button corresponding to it.
3. Adjust the balance controls on your receiver if the sound is only coming out of one speaker or the other. In most circumstances, the sound should be evenly balanced between left and right.
4. Check the fuses inside the stereo receiver. In the event of a power surge, a fuse will blow, which cuts off electricity to the machine and spares the remaining components any damage. Your stereo instruction manual should tell you replace a fuse in your particular receiver.
5. Make sure that the stereo receiver input is set to "Analog" when making a recording to an audio tape or a VHS tape. Many new stereo receivers broadcast in digital, which older components cannot receive. If the receiver isn't switched to "Analog," it will not record to those components.
6. Move the receiver away from any fluorescent lights or tube-box television sets. Sometimes they can interfere with the receiver signal, creating a buzz or a low hum.
7. Check the batteries in the remote and make sure that there is no obstruction between it and the stereo receivers. A remote needs fresh power to work and a direct line to the receiver in order for the signal to get through.
