So, you just dropped a couple of grand on new digital TV setup. You decided to set it up yourself. It is done. Just as your inner handy man is about to do the happy dance you realize the one flaw in this system. You can’t hear anything; not the big game, not the new Blu-Ray that you bought, not even the next episode of American Idol. Don’t pick up the phone to call a professional just yet. Your inner handy man’s ego can be salvaged. You just have to do a little bit of troubleshooting.
Is everything plugged in correctly?
This one may seem basic, but an unplugged or half-plugged-in wire can be a simple fix. Go back to your manual and be sure that your sound cables are in the right port for your TV. Use the labels on the back of the ports, not just the colors. The average digital TV can have sets of ports for many different channels. You may discover that you video is set up for channel three, but your audio is on AUX. While we are at it, you are using the right cord, aren't you? The red, yellow, white combo you are familiar with from old may have been replaced by an optical cable or HDMI cord for the sound, so check your switch positions on the AV receiver and TV, too. (Press the "Mute" buttons on the remotes, too, to make sure you don't have the system muted.)
Did you read the instructions?
Setting up a system may sound like a simple task, but since digital TV makers and accessory makers basically get to design their wares however they like, you may find that your external speakers have a special set of requirements that are different from your TV's standard set up. If you are sure that you did everthing the way that it should be done, just move on.
Did you setup the reciever?
An increasing amount of digital sound systems are not plug and play, like your old analog speakers were. Some models require you to set up the sound reciever. This reciever will capture the analog sound that your TV is putting out, and transfer it over to the digital domain. Don't worry, for most models this is either done through a wizard style piece of software or with a wireless pairing button. As long as you do exactly what the nice book in your hand (the manual) says, you should be able to set this up without too much trouble.
Now you should be able to hear your digital TV crystal clear. If you can’t you may want to think about getting professional help or consider the possibility of a manufacturer's defect.
