The Victor Company of Japan, or JVC, manufactures a popular line of home theater electronic equipment, including receivers that allow you to connect multiple components for a variety of audio/video applications. If your JVC receiver is not working properly, follow these troubleshooting steps to determine if you can easily fix the gear and save money or if an electronics technician might be needed.
Identify the Problem
Determine what aspect of the JVC receiver is not working. Do the speakers produce sound when you adjust the volume? Can you only hear sound through the left speaker channel, the right speaker or the rear speakers?
Check to see if there is a specific component that is not working, such as the CD player connected to your receiver. Is it the DVD or Blu-Ray player, the television, tape deck, VCR or turntable? Narrowing the problem to a specific component will lead you to a solution.
Check All Connections
If your speakers are not producing sound, check the speaker wire connections to the receiver and to the back of each speaker in your system. One loose or disconnected wire will prevent a speaker from working. Also check the length of each speaker wire to determine if there is a break.
Next, check the audio-video connections on the back of the receiver and each piece of equipment hooked up to it. Depending on your system, if the S-video cable, the yellow video cable or HDMI plug is not securely attached to the receiver, you will not be able to see any video from that component, whether it is a DVD or Blu-Ray player, a VCR or the television itself. Also check the white and red audio cables plugged into your components and the JVC receiver. Push the plugs firmly into the jacks and retest the component.
Check the JVC Receiver Functions
Using the push buttons on the front of the receiver or your remote control, select different components and test each one--DVD player, CD player, tape deck, VCR, and any other equipment--to determine if an internal switch is broken. If your DVD player is working normally, but the signal is not getting through the receiver, it could be a defective internal switch for that particular function. Another way to test for receiver problems is to connect a component, such as a DVD player, to a different receiver that you know to be working. If the DVD player operates with a different receiver or amplifier, it is likely that an internal switch circuit has gone bad in your JVC receiver. The other possibility is a blown fuse in the receiver. Check your owner's manual for the correct replacement fuse or write down the model number of your JVC receiver and take it with you to an electronics store to buy a replacement fuse.
Be aware that unless you have an extensive knowledge of electronics and access to testing equipment and replacement parts, replacing a bad internal circuit or electronic components may not be advisable, as you could cause more damage than you are able to repair. However, being able to isolate the problem is still useful because you will be able to explain it to a repair technician, saving time and money on the repair bill.
Taking the JCV Receiver to a Repair Shop
If you are unable to resolve receiver problems with these troubleshooting tips, taking the equipment to a repair shop may be your only option. Find out in advance how much the shop charges to diagnose a problem and ask for a written estimate before you commit to repairs. In some cases, depending on the age of the receiver, it may be less expensive to buy a new receiver rather than repair an old model that is no longer in warranty. Also be aware that if your receiver is still under warranty, you may void the warranty coverage if you take off the cabinet cover and attempt any repairs yourself.
