I set up teac HDB840 to tv- via coxial cable from wall to set top box, then rca cables output of set top box , then to input to tv.-tried av button on tv showing av1 av2 and av3 but still no picture only static. Does the set top box and tv need to be on same channel? Tried menu on set top box to try to reach auto-tuning but nothing happens. What do I need to do? Many thanks

I am assuming this should read 'Set top box'. What kind of cable are you using?

Usually the set top box connects via a SCART lead but yours may be HDMI if it is a very new set top box.

If you are using RCA plugs, you may have cross connected the wrong cables. The RCA cables should be colour-coded. RED and WHITE are for audio, Yellow is for video.

Best advice is to switch it all off, remove all the cables you attached, and start again. The instruction manual/user guide usually has an illustration to help you identify what your set up looks like - there are usually several examples.

If the cables you need did not come with the set top box, you will need to purchase them.

When you are connecting audio leads, you should use the 'audio out' on the set top box and the 'audio in' on your TV set.

It would help to know the EXACT model number of LG screen you have and the make and EXACT model number of the set top box.

Good luck.

Hi,
Your set top box should have secondary RCA outputs along with the HDMI. run another RCA standard yellow- red- white cable to the Onkyo's video 1 input. Use Monster cables for best performance..

If you're using a box that has an RF (antenna) output on channel 3 or 4 to the TV, you can insert a splitter and feed two sets. A splitter looks like this:



It takes the signal in on the single connector side, and splits it between the two output jacks on the other side. You can find splitters at TV retailers, Radio Shack, and even at Home Depot or similar stores in the electrical section. Run a cable from each of the output jacks to the antenna connectors on the two TV sets. Each TV will need to be tuned to the converter box output channel, and both sets will get the same program (whatever channel you have selected on the converter).

If the converter box has audio and video output jacks and the nearest set has an AV input, you can connect that set with the same kind of cable you use to hook up a DVD player (RCA plugs on the ends) and select the AV input to see the converter box signal. You would run a cable from the RF output connector of the converter to the second set's antenna jack. Then you wouldn't need the splitter, and the set using the AV inputs would get better quality picture and sound. Again, each set will get the same program as determined by the converter.

Hope this is what you need to get going. Thanks for using Fixya!

IM GUESSING THIS MIGHT BE AN RCA TELEVISION? if you dont have an rca in hook up on the tv give up and buy a new tv or you can find an older item what it is is a switch that has an rca input and a coax output it was used to hook up the older video game systems it is still sold in most stores and that will work if you do have rca inputs and lost the remote you need to get a universal remote to switch the input on certain older rca tv's you could go to channel 00 and it would set it to the input with the switch you shoudl be able to use it by putting the tv on channel 3

It is your cable box, contact your cable company.

Thats a little tough to do, You need to take apart the TV, remove the welds that hold the coxial in place and sodier on a new one. You could get a cable box from you cable company by requesting one and just use the RCA outputs on that box, you will have to change channels with the new remote but it will work. Also if you have an old VCR you can run the cable into there and the RCA out to your TV, just set your TV on the input you have the VCR coming into and change the channel with your VCR remote.

Either tune your TV to channel 2 or 3 or (on some TV's) to 91.
Then, connect the COAX-output from the set-top-box to the COAX-input on your TV, or connect the "output" Red/White/Yellow RCA-jacks on the set-top-box to the Red/White/Yellow "input" RCA-jacks on your TV.

using your cable box connect the audio and video outputs to the tv via the RCA inputs1, 2, 3, or component inputs on the tv and then select the coresponding video input to view your cable. If you do not have a cable box you can connect your cable to the antenna A or B input jack on the back of the set and set the tv input to antenna

review your resolution setting and maybe there miss the set up..

Darth,
There are 2 ways you can accomplish this.First is the least quality which is via coax.What you want to do is connect the cable service coming from the wall to the input on your cable box.Then the TV output on the cable box goes to the input on your surround sound then the coax goes from the surround sound to the coax input on the TV.The second is to Connect using the RCA AV1 input.what you want to do is look at the back of the digital cable box and locate the OUTPUTS for the RCA jacks(or AV output)connect RCA cables (yellow red white) to the 1st INPUT on your surround sound.depending on models you should have a couple of different INPUTS for a signal.Choose one and plug it in.After that take a second pair of RCA cables and connect them to video OUTPUT on the surround sound and connect them to your AV1 OUTPUT on your TV.With the original remote for your TV,NOT the cable universal one,Look for an INPUT button on the remote.Some are called input some are called SOURCE,TV/VIDEO basically it tells the TV what signal source to look at on the back of the TV.If you dont have the remote put the TV on channel 3 then press the channel down button and when the TV gets to channel 1 press it again and it should start cycling through the AV inputs,choose AV1.


Once you have done this you have correctly
hooked everything up,BUT Like I said depending on the model of surround sound you are going to have to CHOOSE or physically select or "tell" the surround sound receiver which input to RECEIVE the sound through.In general the INPUT on the back of the surround sound will be labeled with something like Video IN,VCR IN, DVD IN and so forth.Make sure the surround sound is selected to Receive the sound coming from the digital box.Sometimes there is a dial on the front of the surround sound that allows you to select which INPUT on on the back becomes active .make sure that what you have selected matches what you have your cable box is connected to.Hope this helps!
