There's no signal from the player's video/audio OUT to feed to the TVs INPUTS, but there is sound from the source speakers

There is also no signal from these same ports with DVD, USB & the FM Tuner. From the 3 Component out jacks, there is no signal too, even after changing TV sets. Please help, Is there a jumper inside or a battery for the boards memory that can be reset to factory settings? Thank you (^^)/

SOURCE: sound no picture, which component is tcon board? where all audio/video/cable/hdmi plug in to?

I have LNS4692D. Returned from vacation, turned tv on - no picture. Tried turning tv off for 4 hours- nothing. Symptoms are: tv is on - no picture , just sound; menu doesn't show, volume bar doesn't show;E.Saving is working - the backlight is changing from lighter to darker.
Found this website and ordered T-con, otherwise known as the LCD panel driver board, p/n# Bn8101286a ( thanks premtech) from partstore.com for $124. Part number BN81-01286A A/S T-CON Board.
Installation:
1.Remove plastic cover. There is an arrow for each screw that needs to be removed. Make sure to unscrew pins next to VGA port. I've spent some time trying to figure out what else is holding the plastic panel until I found this pins.
2. Remove big metal shield in the middle of tv that is covering main components. This shield is being held by small black screws all around it.
At this point you will see cover of T-CON. Here is the picture
http://www.avsforum.com/avs-vb/attachment.php?attachmentid=118863&d=1220531321 (thanks ldac9). Do not attempt to remove that cover yet. Proceed with a next step

3.Remove metal panel that holds main components. Locate big chrome screws that have arrows pointing to them and unscrew them. Remove 2 more screws on the bottom of the panel that holds it together with a box for cables. At this point the main panel will be lose
4. Carefully start lifting the panel. You will see that there are connectors going from components on the panel to components on the lower panel and T-CON. Carefully unplug these components and raise the main panel.
5. Remove 4 screws that holds T-CON cover. Pull the cover so that T-CON is completely exposed. The cover is connected by thin alluminum , don't hesitate to pull it , but don't rip it out.
6. Once T-CON is exposed you will see 2 red ribbons. I've spent some time to figure out how unplug those from old T-CON board. Here is the suggestion. Don't try to pull it out. All you need to do is to lift small plastic lever that is part of a connector. Then ribbon can be slided out. If not sure what to do, see how this is done on the new T-CON. It has a principle of buckle on airplain safety belts.
7. Remove old T-CON and install new you.
8. Follow reverse order.

I've never fixed TV before , but this was totally successful project.

SOURCE: Gurus, I just bought Samsung Home Theater System which i connected to my Hitachi TV with HDMI cable. I have a Optical Cable going from HT to my TV Optical port. I have another connection from my cable

On the remote control for the Samsung Home Theater System look at the bottom left to a button that says "MODE", those moods change the sound each speaker gives off. if that doesn't work, you might need new wiring because there are other wires that are more durable than the ones that come with it, much better too.

How are you connecting the devices?

If you have used the cable box audio out (RCA) to the audio in (the ones just right of the digital coax audio out and the S-video out) on the home theater system, make sure that you have selected the correct Source. (Use the Source button on the front of the system to select AV1 or AV2. This toggles between AV1, AV2, tuner and DVD. It's the right-most button below the display screen. Alternatively, use the Tuner/Aux button (second from the bottom on the left) on the remote.) Note with this connection, the video source cable should go to the TV directly. Unless it is a composite video signal. Then connect the RCA video out (REC out). Make sure that the audio digital output is off. Press Setup/Exit (just above and to the right of the arrow keys) on the remote. Go to the audio menu (press the left arrow key twice) and press OK. The first item in the list is the digital output and should be blank unless you are feeding the audio to another system.

Next try a different audio cable and check that your speaker wires are all connected. Check that the cable box is getting power and a signal from the provider. Connect it to the TV to recheck. If it isn't, make sure that the cables didn't come loose on the box while you were making the connections to add the system.

If you have a newer cable box with HDMI or digital audio out, these most be connected differently. A digital to analog audio converter will work with the second option. For an HDMI connection, connect that cable to the TV, then connect the TVs analog audio out to the NS-H2002. Then go to the Audio menu of the TV and turn on the external audio and turn off the internal speakers. (If your TV has a headphone jack as the only analog out, then this step may not be needed. However, you'll need a 3.5 mm to RCA stereo cable or adapter.)

Check if the audio works with another source (like a DVD). If another external source works, then it's the cable box or the connections to it. If no external sources work but you can here a DVD play, it's probably the input jacks on the system.

I hope this helps. Please add a comment with more information about the cable box outputs and the TVs inputs and outputs if you need additional assistance.

I have a Bose lifestyle 50 (from 1999) and just purchased a new Sony Bravia TV. How can I connect the TV to the Bose sound system?
hello!
unless your "Bose" has an optical or coaxial digital stream audio inputs, there is no way of connecting TVs audio output to your receiver(home theater). to by pass the TV itself, connect analog audio output off your cable or set top boxes. those, still have analog audio out. If you need to connect more audio sources, use TV as a video monitor, connect all the audio outs to your "Bose", instead. In case of terrestrial broadcast, you may need to obtain digital converter box and use it simultaneously with TV to get your audio out. Also, if you lack DVR, that box will allow you to use regular DVD recorder. It's not going to be HD quality, but better, than nothing. You can't feed HD video signal out of TV set.Only analog.
good luck,
Alex.

I have an Onkyo TX-DS575 A/V Receiver and a Panasonic 50 Plasma TV. How do I connect the TV and Onkyo to get surround sound?
Have you looked at the manual? Is the TV REALLY a source of highe-end audio or is it just passing through from somewhere else like the Cable Box?

NO signal ever benefits from multiple connections or 'hops' and it gets expensive zig-zagging a signal all over the room. K-I-S-S is the word of the day. Run the BEST version of any signal directly from its source to the BEST electronics that will present it to you for consumption. The separation of audio and video inputs and outputs on a device is what allows and ENCOURAGES the routing of each signal to the BEST electronics that can process it. Example: your TV does not have the best speakers in the room (we hope) so why send it ANY high-end audio?

If the sound actually comes from an external source treat that source like any other hi-end audio component and attach its highest quality audio directly to the receiver according to ITS manual. The separation of audio and video inputs and outputs on a device is what allows and encourages the direction of each signal to the BEST electronics that can process it.

My problem is conect bose 901v to reciver yahama rx-v657
Here are three options to connect your EQ901B or a BOSE 901® Equalizer to a typical Audio Video Receiver (AVR). See:

https://deercreekaudio.com/blogs-%26-updates/f/connecting-your-eq901-to-an-audio-video-receiver-avr

Option 1: Adding a Separate Power Amplifier - Best Option
This option requires that you add a separate power amplifier.
1) Connect the pre-out main left and right to the EQ901 inputs 1 and 2, and the EQ901 outputs 1 and 2 to the power amplifier inputs left and right
2) Connect your 901 speaker to the power amplifier outputs
3) The equalized signal will now play through the front left and right speaker outputs in the stereo and home theater modes.

Option 2: Setting up Your EQ901 B Using Zone 2 Loop
1) Connect Zone 2 pre-out to the EQ901 input
2) Connect the EQ901 output to any unused analog input
3) Select the Zone 2 source as any input (i.e. CD player)
4) Select the Zone 1 source to the input selected in step 2
The equalized signal will now play through the front speaker outputs in Stereo Mode Zone 1.

Option 3: Setting up the EQ901 B Using Only a Single Source
1) Use this option if you have only one source. This example uses a CD player
2) Connect the EQ901 B in between the CD player and any AVR input
3) This may require the 2V input mode on the EQ901B
The equalized signal will play only the single source (i.e. CD) when the input referenced in line 2 is chosen

I have a set of T 912 wireless headphones. I am unable to set them up on the TV. I am using the white and red cables from the base station to the TV audio red and white. Do you have any instructions on...
The audio jacks on the TV are most likely inputs, not outputs. They're meant to take the audio signal from something like a DVD player, along with the video input on another jack, so you can play it through the TV. There isn't an audio signal coming out from those jacks, and if you connect your headphone transmitter to them all you'll get is silence. Almost all sets now have at least one set of AV inputs, but most don't give you outputs. The manufacturers figure the TV is just a display device, and not a signal source.

Unfortunately, there isn't any easy way to connect your wireless headphones if the TV doesn't have audio output jacks or a headphone connector. If you're comfortable with soldering and willing to do some modification to your TV, it's possible to add a headphone jack. Most people don't want to start tinkering with their sets, though.

If you're using your TV on a cable system without a converter box and the cable hooks right to the set, you're out of luck unless you're willing to add a headphone jack as I mentioned before. But if you have a cable converter box, or you're using a satellite receiver or other set-top box, you can use your headphones with those. These devices typically have direct audio and video outputs available on the rear panel, and you can use that audio output to feed the headphone transmitter.

What most people do these days is use a home theater receiver along with the TV. All sources (the cable box, DVD player, video game console, audio CD player, etc.) connect to the receiver, and the receiver's audio and video outputs go to the corresponding input jacks on the TV. This way, the TV is just the end of the line. The receiver also would provide an output for the wireless headphone transmitter. This system offers some advantages. You'll be able to connect the proper speakers to enjoy surround sound when not using headphones. And you'll be able to use your wireless headphones with the tuner and audio sources like music CDs when not watching TV.

I can't hear the tv i can see the picture
Hello
Either your TVs speaker or its audio output IC has damaged. To confirm which has the troubld, do the following. Place your ears very near to the speaker side of the cabin, and switch ON the tV by its MAINS POWER ON?OFF SWITCH; not by remote control handset. If you can hear a 'thumb' sound from the speaker side of your tV, confirm that the speaker is OK. If so, feed the tV with some extenal audio source; like DVD or CD player to its audio in sockets at its back, play a CD or DVD in the player, select the audio source of your TV to appropriate audio source and listed whether you can hear the sound. If there is sound from this source, make sure that the audio filterins section of your TVs main board has damaged. If there is still no sound from the speakers, make sure that the Audio Output IC of your TV has damaged. OK.

There is no sound on my Sony SLV-D350P DVD Player / VCR Combo. The only section that works great is the VCR, but the DVD player sound just went out for some reason. I've changed the RCA cables, and...
Hi, As long as you have the picture it means that DVD's Laser Eye is Ok.. Pls Check your connections to make sure the audio and video cables of both VCR and DVD are properly hooked up to the television. Color coded cables should be matched with the jacks of equal color. Yellow corresponds to video while red and white are both audio.

 Ensure the DVD is in standby mode if you are not getting picture from the VCR. The DVD cannot be running at the same time as the VCR is playing when you want to see the VCR picture.

Connections with combo units are often inconvenient, forcing you to use separate video hookups for each section (DVD, VCR), a problem for older TVs. This player has it figured out: a single RF or composite-video connection to a television will display either the DVD or the VCR signal, depending on which format you're viewing. If you want to view DVDs in S-video or in component-video (either interlaced or progressive-scan), you will need to use two inputs. though: any component- or S-video-equipped TV will offer sufficient inputs for both of the SLV-D350P's formats.
It's a different arrangement for audio: you can listen through a single set of stereo analog-audio cables for each component or--if you want to enjoy DVDs in discrete 5.1-channel surround sound--you can send the DVD's audio to a compatible audio/video receiver and a multichannel speaker system through a digital-audio interconnect (either optical or coaxial,). The unit also comes with an RF cable that will transmit DVD/VHS audio and video to your TV.
In conclusion,for a best tech solution I prpose you to connect DVD audio directly to your Stereo and listen as separate audio source.while Video goes to TV as usual. Hope this helps! if you need more help pls contact me..Take care and please Remember to rate/vote and give me 4 Thumbs Up for me to continue for Helping out the Community :)

Can't get sound to come from speakers with tv only the radio
You didn't give the brand and model of your TV, and I can't try to find a manual and see what kind of AV connections it has available. So here's some general information.

Many TV sets only have input jacks for external sources like DVD players or cable boxes. When you select an external source, or use the set's internal tuner for TV programming, the video and audio play through the TV. The trouble is that if the set has no audio output jacks, there's no way to get a sound signal out. The TV accepts only inputs

When the TV is part of a home theater system, most people use it just as a video monitor. All AV sources connect to the receiver, and audio is sent from there to the speakers. A video output from the receiver goes to the TV so you can see the picture, and the TV's speakers aren't used. If you have a cable box, FiOS set-top box or satellite receiver for your TV channels, they connect to the receiver too, since they're just another external source.

This doesn't work if you rely on the TV's internal tuner for TV channels, though. This might be the case, for instance, if you have a cable system where a converter box isn't required and your cable connects right to the TV. When you're watching regular TV, then, the sound comes through the set's internal speakers. If there's no audio output available on your TV, that's your only option.

As I said earlier, many TV's have only audio inputs. But some have audio output jacks as well, so the sound has a way out. If yours does, you can connect them to one of the inputs on the home theater receiver. Then when you select that input you'll get the TV sound through the speakers connected to the receiver. Depending on the design of the TV, you may need to leave the TV volume turned up. Some sets have outputs that are follow the TV's volume setting. On others, the output is an independent fixed level. Then you can turn the TV volume down and use just the receiver's speakers if you want.

Check the connections available on your TV and look for a set of "audio out" jacks. Your TV's owner's manual should have a section explaining how to connect it in different ways. If you need a copy, most manufacturers have manuals for download on their website.

Good luck with your sound, and thanks for using Fixya!

Having trouble getting tv set up. It has on the screan No Signal
When a TV says "no signal" it means it cannot find a video sync present on the input which is currently selected. Knowing your TV Manufacturer and model would help tremendously, as would knowing what it is hooked up to.
For starters, it could be one of a few things:
  • It is selected to an input to which there is no source connected [SOLUTION] make sure the TV is set to view the correct input (INPUT or SOURCE) button.
  • The cable between the source and the TV is bad, or the plugs are not properly seated at both ends of the cable [SOLUTION] Make sure that BOTH ends of the cable are pushed all the way in, and securely seated. If that doesn't work, try replacing the cable with a different one
  • You have the cables connected incorrectly (for example, a composite video signal (yellow) will fit into a left or right audio connector (red or white). If you are plugging in by reaching around but can't see, this could be a problem. I have also seen people plug video inputs into outputs (many TVs have a video loop out, so if you plug something IN to that you aren't going to get picture. [SOLUTION] Make sure you physically inspect the inputs on the TV and outputs on the source
  • It is trying to use it's internal tuner (if it has a digital tuner) and there is no cable or antenna feed attached [SOLUTION] make sure the TV is set to view the correct input (INPUT or SOURCE) button.
  • The source you are trying to watch (DVD player, etc) is not turned on [SOLUTION] verify that the source is plugged in and outputting video
  • The TV is defective. [SOLUTION] take it back . . . its a lemon.
