Question about RCA F27450 27" TV

1 Answer

No audio RCA F27450 27"

I have no audio output from the speakers or headphone jack; any suggestions as to possible causes/remedies would be greatly appreciated! If repair is required, do you think this is a problem worth fixing, or is it time for me to break down and buy a flat screen?

I suspect what you're wanting to do is take the audio output from the TV and run it through your stereo system to leverage the large speakers. Correct?

I suggest using the RCA audio jacks (red and white pair) on the back of the TV. Most TV's still have these. Some are tied to a specific component, and some are general for all sound coming out of the TV. You connect this to the input RCA jacks on your stereo system.

The headphone jack on the TV could also work, but I suspect it may have a low level output. I don't understand how you say your MP3 player plays fine through the headphone jack, as that's an output, not an input. Unless there's some other jack?

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

Hope this helps!

Hello joebobstgeor,

I wasn't able to lookup a manual for the Sharp GB960. In fact, manuals for any Sharp car audio product was woefully absent.

Try connecting the cables to the input of an amplifier. Female RCA jacks are used for low-level (preamplifier) outputs for subwoofers, sound processors, and additional amps. The impedance of the output is typically in the 20-25Kohm range and would not produce any sound in speakers or even low impedance headphones.

It's also possible that the RCA cables are an "AUX" input to the receiver and not an output. Although many of the mobile audio manufacturers are now using front-mounted phone mini-jacks as "AUX" inputs, some still have rear mounted RCA's.

Hope this helps.

Audio from tv is not restored by turning off power on headphones
It sounds as if you are plugging the base into a standard headphone jack located on the Television set.

RCA Headphone jacks (incl mini) automatically stop the sound output to the main speakers on almost every set I have seen.. or home stereo.. etc etc

In other words you can take a standard RCA jack.. with nothing connected to it.. plug it in while the music or sound is coming out the main speaker.. and it will cut off the output to those speakers..

If you set has audio outputs on the back.. preferably Fixed Audio Out .. you will need to connect your base unit to those.. turn your set volume to 0 and adjust the headset volume using the control on the right ear-cup.

If you have variable audio out.. you will need to go into your TV sets setup menu.. turn off the speaker.. and turn up the set until you achieve a signal and decent volume through the headset.

If you are missing these connections.. your current “work around” is your only solution.

Best of luck

Using 2 Pc speakers on my Tv
1)probable incompatibility issue--for comparison did you try a set of headphones? 2)The RCA audio outputs on the tv can go to an amplifier that has speakers attached,ie surround sound. 3)Caution==never try to alter vol level at spkr!

Audio output jacks
If I remember this tv correctly, check under the audio setting in the menu, most tv's including this on have variable output for the audio o/p. meaning the the o/p vol. is adjusted as the tv speaker vol. changes. some tv's will put out a fixed audio o/p to the rca jacks, but will only do this when the speakers are shut off in the menu (not muted, but off). I have run into this problem many times & have yet to find a better solution to getting a steady sound sound out of the o/p jacks.

Adding Audio Output to TV
headphone jack is perfect. Buy ( radio shack, ebay,home depot,best buy ) the mini plug to rca breakout cable and once you plug it in it should mute speakers. Otherwise go into menu, audio, and usually there is a selection to cut off speakers

I have a 2006 Sony TV big screen, I turn the Tv on but it clicks back of within seconds. I have a Sony TV big screen. I bought it in 2006. The TV wouldn't come on so I purchased a lamp for that model, that I had bought new in case that the old one went out. It wouldn't come on before I changed it. So I thought that that was the answer. We changed it and it was still turning off an on but it wouldn't stay on and it is still doing it.
