    I don't understand sweet rascals response..

  • mtyler48 Jun 24, 2008

    I'll try blowing the jack out but since it never worked from purchase it probably is a bad jack. thanks for the contact to customer support however the link for the manual is not my tv it is for a dvd player.

  • mtyler48 Jun 24, 2008

    i have some knowledge of electronics and can attempt the replacement. i didn't want to do that if it was a setup issue.

Hi,

Based on your postings, it is not a setup/configuration issue, it is a hardware issue. Your TV has only two (2) source settings: line or cable. The "line" has two possible connection points, front and back. the front works but the back does not and you'd rather use the back. Corrective measure would require that you open the back of the unit, chances are 2 ~ 4 screws, the 3 RCA females would be soldered unto a smaller PCB. As VOTIT has posted, check the yellow RCA (video). Most likely problems would be cold or no solder, cracked PCB trace, loose connector, stretched/open wire or even in some cases, wire(s) simply not connected.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Tech48 has it correct. It is a common problem for poor solder connections to exist on the jacks. While rare, the video switching chips have been known to be defective as well which would show up as the audio working without the video. The audio section is switched using a different chip. You have stated that this has never worked. If by chance, the unit is still in warranty, you should be able to get this repaired for no cost. Even if the chip is defective, this is a simple repair and should not take very long.
Keep use posted.

Since the audio works on the back jacks on the TV, you have it plugged in right. If you switched the audio and video around you would not get audio from it.

If you have audio from it, you have the right input selection on the TV

Since the audio and video both work on the front jacks of the TV you know that the DVD player is not at fault.

This only leaves one option, the jacks on the back of your TV for the video are not working. It could be a bad solder connection. But it could also be the buffer IC that is on the input board in the back of the TV.

Those are the only really likely problems. Check the solder connection, and if they look good you may just need to take it to a service center. Replacing the buffer IC may not even fix it. You may have some other problem like a shorted transistor or somethiing in that cicuit. The only real way to tell is by doing some real electronic troubleshooting. Anything else is just a guess.

If you have a multimeter and an O-scope and the knowledge of how to use it, you can check the components around that cicuit. It could even be a faulty switching IC. It is going to take a little experience with this type of troubleshooting unless you just have a broken solder joint connection.

Let me know if you want any more help from me.

    One other thing, try connecting a different video device into that jack on the back of your TV. If it does not work, just like the DVD player, that isolates your problem to the TV.



    If you have the option to select different video inputs (like composite, s-video, component) from one source (like video 1 or video 2) just double check that and make sure you have the proper video type selected.

    If you are plugging your cables to video out and audio out then you will not get a picture or sound. The cables need to be plugged into the video in and audio in of your TV. There is definitely possibility that the only input on this TV is in the front as the TruTech brand seems to be made rather cheaply, there is a lot of dissatisfaction with this Target house brand around the Internet.

Before doing all this reparing work just clarify your sely that you are inserting the wires of video in the proper jack try interchanging the wires in the jacks then start further some times the silly mismatch creates this problem.also try cleaning the inner side of jack by blowing air through your mouth or air blower if you have it,minute dust can also be the problem.then try the further solutions.

this is the link to help you to get the manual of your product.

  • dewan nafees ahmed Jun 24, 2008

    you are telling that the video jack in back side alone is not working right??

    there is nothing to do with settings of TV i think.

    u just need to change the back jack alone.

    that is not a difficult job. if u have a knowledge about electronics u can check it easily and change it.

Connectding audio/video cables when you have a cable box and sound bar with dvd player


How To Connect a DVD Recorder to a Television:
1.If you want to use higher quality cables, then you may want to connect the TV Source (Cable and Satellite only, not Antenna) to the DVD Recorder using Composite, S-Video or Component video and audio cables.
2.To use composite cables (also known as RCA, the yellow plug is video, the red and white plugs, audio): Plug in the composite cables to the RCA outputs on the back of your TV source and then plug in the composite cables to the RCA inputs of the DVD Recorder. Then connect the RCA outputs from the DVD Recorder to RCA inputs on the TV.
3.To use S-Video and RCA audio cables: Plug in the S-Video cable to the S-Video output of the TV source. Plug in the S-Video cable to the S-Video input on the DVD Recorder. Next, connect the RCA audio cable to the output on the TV source and the input on the DVD Recorder. Finally, connect the S-Video cable and the RCA audio cable to the output on the DVD Recorder and the input on the TV.
5. To use Component Video cables and RCA audio cables: Connect the Component Video cable and the red and white RCA audio cables to the outputs on the TV source and the inputs on the DVD Recorder. Next, connect the Component Video cable and RCA audio cable to the outputs on the DVD Recorder and the inputs on the TV.
6. Now that the TV source (either Cable, Satellite or Antenna), the DVD Recorder and the TV are all connected, you need to configure everything to make sure that TV is coming through the DVD Recorder, for recording and viewing.
7. Turn on the Cable Box or Satellite Receiver, TV and DVD Recorder.
8. If you connected everything using the RF connections then the TV should be passing through the DVD Recorder and displaying Television on the TV screen. To record in this mode, you would need to tune to either channel 3 or 4 on the TV and then use the DVD Recorder TV Tuner to change channels and record.
9. If you made connections using either Composite, S-Video or Component cables, then to view or record TV, two adjustments need to be made. First, the DVD Recorder needs to be tuned to the appropriate input, typically L1 or L3 for rear inputs and L2 for front inputs. Second, the TV also must be tuned to the proper input, on a TV usually Video 1 or Video 2.
10. If you have a Dolby Digital 5.1 Surround Sound A/V Receiver you can connect either a Digital Optical Audio cable or Coaxial Digital Audio cable from the DVD Recorder to the receiver to listen to audio through the receiver.

Cannot get DVD's to play on our TV.


It depends on what kind of inputs your TV has; here are a few of the most common, all of which your DVD player supports (best quality first):

1) COMPONENT VIDEO (Red, Green, Blue)
If your TV has three inputs for video colored red, green, and blue, this is your best bet for quality video from your DVD player. You may need to buy a component video cable from the store (somewhat pricey, but great quality) which consists of three cables (again, red, green, and blue) stuck together. Just plug the red/green/blue cables into their correspondingly-colored ports on both the DVD player and the TV.
That covers your video. To set up audio, you just need some regular red/white RCA cables. On the DVD player, plug the red/white cables into the correspondingly-colored audio out jacks NEAREST to the red/green/blue cable you used earlier for video, then plug the other end into the audio in red/white jacks on the TV.

2) COMPOSITE VIDEO (Yellow)
If your TV has a yellow input for video, just use a regular yellow RCA cable. Plug it into the yellow video-out jack on the DVD player, then plug the other end into the yellow video-in jack on the TV.
To set up audio, you just need some regular red/white RCA cables. On the DVD player, plug the red/white cables into the correspondingly-colored audio out jacks NEAREST to the yellow cable you used earlier for video, then plug the other end into the audio in red/white jacks on the TV.

3) COAXIAL JACK (Antenna port)
If your TV only has a coaxial jack that you currently plug your antenna or cable line into, you'll need to buy an RF modulater and a short length of coaxial cable (you can find these anwhere: Walmart, Radio Shack, etc).
Plug the RF modulater into an electrical outlet, then plug your antenna/cable line into the "antenna in" jack on the RF modulater. Take the coaxial cable that you just bought and plug it into the "antenna out" jack on the RF modulater, then plug the other end into the antenna/cable jack on the TV. The RF modulater should have a switch on it somewhere that sets either the number 3 or 4; depending on which number you pick, that's the channel that your TV has to be switched to to view the DVD player.
Now you're all set to connect to your DVD player. Just follow the instructions in section (2), only now you're going to plug your cables in the RF modulater instead of the TV.
(I hope this wasn't too confusing; it really is a lot simpler in practice than it is in explanation...)

Need instruction to hook up dvd player


You will need a TV or monitor with audio/visual inputs. The better ones have what is known as an S/VHS input, which separates the TV picture signal for better color reproduction. You will need to be able to switch your TV, usually by the channel selector, to the proper input for audio visual signals. Sometimes this is known as Video 1, Video 2, A/V etc. These are usually below Channel 2. Maybe your remote has that option. You will need an a/v cable. This is a three-connector cable with RCA plugs on each end. Connect the DVD player to the TV as follows: 1. Yellow cable, from video OUT on the DVD player, to video IN on the TV. Video is ALWAYS yellow. 2. Red and white cables from audio OUT on the DVD player to audio IN on the TV. 3. If you have S/VHS capability, buy an S/VHS patch cable which will have the three plugs mentioned, plus a round 4-pin plug. Select S/VHS OUT on the DVD player, and S/VHS IN on the TV. When using S/VHS, ignore the yellow connector. It is for composite video and not needed. Here's a hint: Your YV audio/visual inputs will usually be on the back of the set. Some better units have a/v inputs in front. What if my TV doesn't have a/v inputs? If your DVD player as an RF output, connect an RF "f" cable from that output to the antenna in cable on your TV. Otherwise buy an RF converter (about $20 or so at Radio Shack). Connect your a/v cable (yellow, red and white) from the DVD player to toe converter, then connect an RF cable (like the kind your cable box is connected with) to the antenna input on your TV. This signal usually comes in on Channel 3. Let me know if your problem is more complicated, It seems like a lot of wires and connections, but it is really straightforward, Remember, yellow is ALWAYS video. The two audio cables can be connected without worrying about color.

DVD player hook-up problem


Using the composite video connection method is pretty straightforward. you will be dealing with one video cable (marked in Yellow), and two audio cables (marked in White and Red) Red is right channel and white is left channel if stereo, if mono use the white marked cable. Look at the back of your DVD player you will see the video out RCA jack (marked in yellow) plug one end of the video cable into this jack, the plug the other end of the cable into the TVs Video In jack (marked in yellow) Then plug the audio cables into the Audio Out RCA jacks of the DVD player Red marked cable to red jack White Marked cable to white jack. After this is done plug the ends of the sother side of the cable into the Audio input of the TV white to white, red to red. At this point you should have video and audio once you set the menu of your tv to accept input from the Composite input and the audio jacks. I hope this helps.
