To troubleshoot a JVC TV, reset the television, adjust the brightness and contrast, and replace the audio cables. The specific steps for troubleshooting a JVC TV depend on the particular problem.
A TV that has no power is a common problem that is easy to fix. Begin by checking that both ends of the power cord are properly connected. Next, plug the television directly into the wall to ensure that the power strip is not faulty. If this does not work, unplug the unit for at least 10 minutes, and then plug it back in to reset it.
Poor picture is another common problem with JVC televisions. To fix the problem, ensure that there are no electrical appliances close to the unit. Other electrical appliances may sometimes interfere with the television’s picture quality. Next, press the Menu button on the remote, and navigate to the Picture Settings. Adjust the brightness and contrast to fix the problem. Standard-definition programs can appear blurry on a high-definition television.
Lastly, poor sound is a common problem with televisions that users can fix by first ensuring that the television is not on mute. Next, check that both ends of the audio cables are plugged in fully. Inspect the cables for damage, and replace if needed to resolve the problem.
