Question about Sharp LC-C5255U 52 in. LCD TV

1 Answer

No audio output

I suddenly have no audio output from both the RCA outputs on the back of the TV and the TV's speaker. I've read a post explaining how to "factory initialize" thru the service menu... not sure if this is the best thing to do . Any insight here will be greatly appreciated.

If you do a factory initialization, nothing wrong could happen, except with its tuning settings. All the setting in the memory will be cleared, and the set will work as if it has been bought new. You should have to re-tune it and do all personalized settings again. That's all. In my view, for this case, doing a factory initialization will be better. If you do not get audio even after factory initialization, you should have to check its mother board's audio processor section circuit for the fault. If you wish to get some details, check the site linked here. Pull up older posts.

SOURCE: Blink on Sharp Aquos LC-32D43U

If your using a HD converter box, there is usually a blink when switching from an HD channel to a non HD channel. It is just adjusting from different pictures modes such as changing from a 480i channel/show to a 1080i channel. If this is the case, its perfectly normal.

SOURCE: Digital Audio Output on TV

When using HDMI as the source, the Dolby Digital data will NOT be passed through. If you switch your cable box or satelitte receiver to PCM audio it will pass that through.

SOURCE: no sound from audio output This set is new.

The speakers need some kind of amplification, if you have something like a set of computer speakers connected and they are not powered they won't work, try connecting them to the headphone jack.
Let me know the set up, what kind of speakers, audio settings from the tv menu.

SOURCE: Can't hear the output speakers

Make sure you have the cable hooked to output. Go into your televisions menu and set the speakers to external. That will disable the interior speakers on the television. there are actually two options. You can set it to fixed output, internal speakers off. This is best for just using the Bose speakers all the time. Or you can set it to variable output; internal speakers on. That way you can watch TV late at night and use the internal speakers and not "bother" those sleeping. Or crank up the Bose when everyone is watching! Make sure you have the Bose set to the proper input as well. Good luck!

SOURCE: I want to hook headphone

That jack is meant for connecting to Home Theater Systems or to computers not for headphones but it may still work. If you go to your menu and find Output Select change this option to variable. On the off chance it works you might want to be careful when testing... it may lead to sudden deafness if its too loud. By the way this will turn off the sound coming from your speakers.

Hope that helps!

There's probably a digital audio output you can use if you have a digital receiver. If you don't have a digital receiver you can take the audio out from the cable box or satellite box. Since I have an old analog receiver it's the way I connect my equipment. I use a hdmi cable for the TV so it frees up the rca output jacks on my cable box. Works great.

Your TV has a pair of analog RCA Audio Outputs on the back of the set. They are the red and white, female, round outputs and should be labelled as Audio Out. If you have a surround receiver or stereo that accepts this type of input (most do), then you would purchase a stereo RCA audio cable that has the red and white male ends on both ends of the cable and plug them in to the appropriate stereo RCA left and right channel audio inputs on your receiver and the aforementioned outputs on your TV. The same is true if you have a pair of self-powered computer speakers (or similar). If your external speakers or audio systems don't have the RCA inputs, you may need to get an adapter to convert the RCA output to stereo mini-jack (or similar) to match the appropriate input on your external speakers. Does that make sense?

How to add an Exterior Speaker to Sony KV-13M10

Welcome to FixYa!

To add an exterior speaker to Sony KV-13M10, you have to have an AMPLIFIER.
  • At the back of your TV you will be able to see 3 RCA output namely = VHF/UHF, Audio and Video.
  • Use an RCA cable and connect to the Audio output.
  • At the back of your amplifier, connect the other end of the RCA cable to an RCA input labeled Audio - L (left, usually in white color).
  • Your speaker should be connected to your amplifier labeled output or audio out. The connection type depends on the make and model of your amplifier. The speaker wires usually come in red and black color. red goes to red, black goes to white.

A simple diagram will look like this:

TV audio out -------------> amplifier audio in (left, white color) amplifier audio out (left, white color) -----------> speaker (black wire) amplifier audio out (right, red color) ------------> speaker (red wire)

Thank you for using FixYa.
Have a great day.

I have external speakers / woofers with amp ..what i nedd is to connect those with my Sony bravia LCD TV.. i mean i need the audio output from the TV which will connect with the external speakers .. if...

I do not want to sound patronizing, but I have no idea how much you know about wiring ... so I'm probably going to over-explain everything. Hopefully it won't read like stereo instructions ... ha ha ha
Depending on your TV, theremight be a door covering the wire access .. or there might be audio outputs on the front of your TV ... but these are more likely to be inputs for game consoles and other things. You should have a red and a white jack in the back of your TV marked "Audio Out" ... those are left and right audio outputs from your TV. Use RCA cables from Radio Shack or wherever and connect that to your amp left and right audio inputs -- the RCA jacks should be the same color as the wire connecting them, which makes it easier to trace wires later. Generally, the amp should have a red and a white RCA jack as well .. make sure they match your wires , too ... or you'll end up hearing things in reverse. You should find sterio wire inputs on the back of your amp -- if your speakers have the wire connected, set them up and then plug them into the appropriate jacks. There shoud be some sort of lever on the side of each of thee jacks, push it open and insert the wires. Some of these are spring-loaded so you might have to keep your finger on it to hold it open. Just put a bare cord from the speaker into it, and make sure the lever closes again, securing the wire. Your amp should have the left and right speaker outputs, subwoffer output, and everything labeled, but you'll probably need a lot of light on it to see it (usually it is just a recessed or relief letter L and R for the left and right speakers.
I am not exactly well off, so most of the electronics I have are a bit old. You might only have a different audio output from your television, in which case I would recommend speaking with someone at Radio Shack -- they tend to know a lot about wiring electronics together (more than at Best Buy or other big-box stores) or if you don't have one of those around, find a local electronics store, or a pawn shop ... people who work in these types of places usually enjoy the challenge of putting a round plug into a square jack.

Don't know how to connect to tv

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.

I want to connect the z2300 speakers to an LCD tv. Do I need a special cable?

try to check your speaker if what type of cable your speaker have...your LCD tv i think its a RCA connector, so you have to insert the RCA connector to the output audio label,,,then the cable which is also an RCA output must be connected to a RCA female connector ....again the output the your female connector will depend to what your speaker output its minijack or RCA then the output must be female RCA of mini jack also.
