Does my tv have audio outputs? - LG 42PG20 42 in. Plasma HDTV

Be sure you are hooking up the Audio Output from the TV or satellite to the soundbar.

From the satellite box both Audio Output and Video Output go to the TV, and then Audio Output from the TV goes to the soundbar.
Or
From the satellite box Video Output goes to the TV and Audio Output goes to the soundbar.

How have you connected the audio cables to the TV? The 3250HD has component, DVI, and composite video out. There is also two analog audio outputs (for the component and composite video) and a digital audio output. Make sure that you are using a TV and not a monitor. Many monitors do not have built-in speakers. (In that case, use external speakers.)

If you use the digital audio output, make sure that your audio receiver audio input is connected to the set top box audio out. Then make sure to set the correct source for that audio signal. (Note the TV may have a digital audio port; that is an audio out.)

If you are using one of the analog audio outputs directly to the TV, make sure that you are using the correct set of audio IN on the TV and audio out on the set top box. (If you are on the Component input, your audio won't be heard if you are using the Composite audio output.)

Next try different audio cables. Make sure that the TV speakers are on. (Some TVs have an option to disable the speakers if you use external speakers at times.) Try connecting the audio output to a receiver and speaker system (or speakers with aux in). You might need an RCA F/F to 3.5 mm M adapter for some devices. If another set of speakers do not work, then the set-top box probably has a broken audio output. If another set of speakers work, then the problem is with the TV audio. This could be a problem with the jack or the speakers.

I hope this helps.

Check the speaker first. Check if there is any sound output comes from the audio out terminals at the back of the TV, by connecting them to any external audio out devices; such as an amplifier or so. If there is audio output comes from the external source such connected, and no audio output from the TV; since the speakers are good, the fault is with the audio output section circuit inside the TV. If there is no audio output from the external sources too, the fault is with the audio processing section circuit at the main board. If this is the case, main board is faulty, and should be replaced.

If the TV has audio output available, there will be RCA jacks somewhere for that. The standard colors are red for the right channel and white for the left, and they'll be clearly marked as audio outputs. Not all sets have audio outputs, though, while they usually have audio and video inputs. So if you find RCA jacks on the set be sure to see how they are marked.

If the TV has output jacks, all you need is a cable with the appropriate plugs at each end. The TV needs RCA plugs, while the input connector to the speakers varies by manufacturer. Typically the speakers will use a 1/8-inch stereo jack if they were made to be used with a computer, and RCA jacks if they were meant to be used in a home-theater setting. In TV sets with audio outputs, the output may be fixed and independent of the TV volume, which means you can turn the TV volume down and use just the external speakers. Or the audio output may vary with the TV volume, meaning you'll always need to have the TV volume on as well. Some people find this annoying.

If the TV doesn't have an audio output available, you can't hook the speakers to the TV. What most people do in that case is use the TV as a video display in conjunction with an AV receiver. The audio and video sources connect to the receiver, which in turn drives the speakers and provides a video output to the TV.

Connect the audio outputs jacks from the TV to any available audio input terminals on the Yamaha receiver, other than the phono input. You can use any analog audio Left (White) and Right (Red) inputs on your receiver such as the DTV/CBL, SAT or VCR input. There are no special settings needed on the receiver, other than selecting the correct input. There may be some settings that will need to be changed on the TV. Consult the TV ownersEmanual for setting up the TV to output audio to an external source. If youre TV has a digital output (Optical or Coaxial) it can also be run to one of the digital inputs on the Yamaha receiver, such as DTV/CBL or DVD. There may be some settings that will need to be changed on your TV. As always, consult the TV ownersEmanual for setting up the TV to output digital audio to an external source.

NOTE: When the source of the audio signal is coming from an HDMI device connected to the TV, the TV may not output in 5.1 surround sound.

You have a red and white composite audio cable the simplest way is to hook that to your audio output on your tv then obviously the other end goes into the soundbar. Make sure its an OUTPUT not input on the tv, if you hook it up this way everything that plays on your tv will then play through the soundbar.Some tv's do not have an audio output if this is the case then you will have to hook it up to an output of another source such as DVD player or cable box. There are two other possible audio outs on your tv they are fiber optic audio and digital coaxil audio but usually not the case as they are usually only inputs. One other thing some tv's(very rare) require you to go to menu to enable audio out. There is one other possibity and that is HDMI which carries picture and sound but again TV's rarely have this output.

Hello,

Adjust the system's audio output settings. These settings are mainly used when the system is connected to audio devices that support digital audio output, such as AV amplifiers (receivers) for home entertainment systems.
1.
Confirm the formats supported by your audio device.
Settings vary depending on supported formats. For details, refer to the instructions supplied with the audio device.
2.
Select (Sound Settings) under (Settings) in the home menu.
3.
Select [Audio Output Settings].
4.
Select the input connector on the audio device. Channel numbers and audio formats that are supported vary depending on the connector in use.
Input connectors on the TV or AV amplifier (receiver) PS3™ system output connectors Channels that can be used for output 2 Ch. 5.1 Ch. 7.1 Ch. HDMI HDMI OUT connector Digital Out (Optical) Digital Out (Optical) connector - Audio Input Connector / SCART / AV MULTI AV MULTI OUT connector - - 5.
Select audio output formats.
Select all output formats that are supported by the audio device in use. If [Audio Input Connector / SCART / AV MULTI] is selected in step 4, the screen for selecting audio output formats will not be displayed. If [HDMI] is selected, you can also select to automatically set the audio output format. (In this case, the HDMI device must be turned on.)
6.
Check your settings.
You can go back to the previous screen and revise the settings by pressing the button.
7.
Save your settings.
The audio output settings are saved on the system.
Hints

• [Linear PCM 2 Ch.] audio is set to be output from all output connectors by default. If you change the audio output settings, audio will be output only from the connectors that were set.
• If you change the audio output settings, the system will no longer be able to output audio from multiple output connectors at the same time. For example, if your system is connected to a TV via an HDMI cable and to an audio device via a digital optical cable and you switch to [Digital Out (Optical)] under [Audio Output Settings], audio will no longer be output from the TV. To output audio from the TV, switch the setting to [HDMI], or select (Settings) > (Sound Settings) > [Audio Multi-Output] and set the option to [On].
• If you select [Linear PCM 2 Ch. 88.2 kHz] or [Linear PCM 2 Ch. 176.4 kHz] in step 5, sound may be intermittent or may not be emitted from some audio devices.
• When using an HDMI cable, only [Linear PCM 2 Ch.] audio will be output from PlayStation®2 and PlayStation® format software. To output Dolby Digital or DTS audio, you must connect the PS3™ system and the audio device using a digital optical cable and switch to [Digital Out (Optical)] under [Audio Output Settings].
• If a device that is not compatible with the HDCP (High-bandwidth Digital Content Protection) standard is connected to the system using an HDMI cable, video and/or audio cannot be output from the system.

if your tv has an audio output other than the hphone jack. either an optical or composite audio output.

On some sets that have audio output jacks, the level of the audio output on the RCA jacks is fixed, and it does not change with the TV's volume control. On some sets, such as Sony, you can choose fixed or variable output. I have also seen some sets that have both fixed and variable RCA jacks on the back. With variable audio out, the audio level at the audio output jacks follows the TV's volume control. If you go into the TV's menu and navigate to the audio page, look for fixed or variable output options. If you have the owner's manual, read the section on audio output. If variable output is not an option on your model, then the level is constant and the volume will have to be adjusted with the stereo's volume control.
