SOURCE: want to connect pc speakers

Hello,
Your TV should have an AUDIO OUTPUT other than optic..at least " Headphones" output..
You can connect TV audio output with a RCA cable.
white and red audio jack....
since SUB has both RCA and "3,5mm Headphone female Jack"..here are the options;
** you need to buy a cable one end 3,5mm MALE headphone jack and the other end 2xRCA stereo (or 1x RCA for mono or you may need "Y cable " ) to be connected to your TV...
** or 2x RCA
white and red audio jack and connect from your TV..
**" "Headphones" output to SUB with 3,5 male-to-male cable ( the least recommended)
And you need to connect front,centre and rear speakers to your SUB as well...
Take care and if it succeeds please Remember to rate/vote and give me 4 Thumbs Up
for Helping out the Community :)

Hope this helps!

SOURCE: Hi my hitachi p42ho1au has no sound out of the tv

I am not familiar with your TV but I know my TV has a setup option that allows use of the internal speakers or an external amplifier.

When plugging in a wireless headphone in the audio output the tv's speakers shut down.How can I stop this


The speaker cutout feature whenever the headphone jack is connected is a hard-wired feature of the headphone connector, and cannot normally be bypassed without further electronic circuitry and the associated surgery to install a custom modification in the TV. In order to keep the TV speakers on while using the sound elsewhere, you will have to take the audio output from the IR Audio port, if there is one.

Tv no sound and vol no working on remote hitachi


Mrs. Tremelling: One quick and simple thing you can check: If your TV has a headphone/earphone jack, plug the phones in and out a few times. When you plug in the phones, a small switch "opens" (turns off) the connection to the speakers. Sometimes it gets a little grimy (particularly in old TV's) and sticks in the open position.

Good luck, from a retired TV tech...

Can't get any volume on my zenith tv


Put ear right to speaker to see if hum etc----if opened look to see if speaker paper is gone from old age---last is if it has a earphone jack on set that can cause this also.

No sound


check the volume adjustment first, if ok tried to hooked up a powered pc speaker at the earphone jack of the tv. if you get sound there it could be the speaker is worn out. if can get sound from the earphone jack, the amplifier circuit or the amplifier ic was defective.

No sound for earphone, there are no rca jacks, the earphone is used to attach speakers, but there is no sound from the earphone jack


if their is a sound from the internal speaker then the problem is with in only in the earphone jack or in the connection. to access the internal part of the tv you need to remove the rear cover. locate the earphone jack terminal re soldered and check the connection at the board ( PCB). you can check also the continuity, attached powered pc speaker then use an analog tester and check weather their is a connection coming from the stereo input jack going to the terminal of the earphone jack of the tv. if no connection replace with new earphone jack. good luck hope this can helped.

Speaker is off


Most of these combo units do not have a speaker ON or OFF setting but look anyway.

If the set has a earphone jack that may be the problem--see if works with earphone plugged in.

The socket the jack goes into can get flaky as when jack is inserted it turns the sound OFF.

Also put your ear right to the speaker to see if anything at all is heard--the speaker could be bad--but check the above first.

No sound


Hello
If picture is OK and there is no sound output from your tv, means either its speaker or the Sound output Ic is not working. The case of speaker fault can be easly detected without opening the TV. You just place your ear very near to the speaker side and switch on the TV by AC mains [not with remote control]. You may hear a "thumb" SOUND OR A "HUM" sound from it. If any one is there the internal speaker is working fine. The fault lies in audio output Ic stage. If there is no sound said above, speaker can be suspected. Befor confirming that the speaker is faulty, if your TV has an earphone or headphone jack in front, insert the earphone or headphone socket into it, and check whether there is any sound heard from it. If there is sound from headphone, means that the headphone socket is faulty, it does not bypass the sound to the speaker. When head phone is connected, the connection to the speaker will automatically cut of. When it is pulled out from the socket, the speaker connection will resume. If the changeover switch inside the earphone socket also show this kind of trouble. If the speaker inside is found faulty, unscrew it out of place after opening the TV, go for a same type and number, impedence and shape.
If there comes the above said "HUM" sound from the speaker, surely the Sound Output Ic is faulty. Replacing it will solve the probelm. Before replacing it, check it soldering points for any loose contact. It is best to resolder all suspected point is sound section before replacing the ic.
Note: In modern TVs there will be any trace of sound, without a video signal. Without video, sound is muted. ok.
