I am attaching a digital set top box to this TV Model C21F200 and have a video/dvd player to attach as well. I can't seem to get both working. Can I tune the video to the TV with the set top box attached?


If your TV has AV inputs available, you can connect the video player there and switch to that input to watch it. I don't think your model does, though; I think it has only an antenna input connector. This means your set-top box will connect there but you have no place to connect the video player. In fact, most new video players only have AV outputs, and don't have an RF (radio frequency - a channel 3 or 4 TV signal) output connector, and you'd have problems connecting it anyway.

All is not lost, although you'll need some extra parts to hook everything up. I'm assuming the set-top box (STB) is going to your TV on channel 3 or 4, using a cable from the box to the TV antenna connector. If your video player does indeed have an RF output, the simple thing to do is get a splitter. They look like this:

Normally, a splitter is used to break one input signal (into the single connector) into two outputs (the connectors on the other side). But you can also use one backwards to combine two sources. So you can connect the RF cable from the STB to one output jack, connect the video player RF cable to the other, and connect the "input" side of the splitter to your TV antenna jack. If your STB is set for channel 3 output, set the video player for channel 4 so they won't interfere. Then you can tune the TV to channel 3 for TV signals from your STB, and to channel 4 for videos. I know, it sounds confusing.

If your video player doesn't have RF output, but just video and audio outputs, you need an RF converter. This device takes the AV output from the player and generates a channel 3 or 4 RF signal the TV can tune in. A typical converter looks like this:

pgh_pa_guy_14.jpg
Connect the AV outputs from the player to the jacks on the converter. The output cable from the STB will go to one of the round antenna connectors on the right, and the cable from the other one goes to your TV. When you aren't playing a DVD or tape, the converter passes the signal from the STB through to the TV. When you turn on the video player, the converter switches and you'll see the picture from the player. Most converters switch automatically, but on some you might have to flip a switch. RF converters are available from retailers who sell TVs or online.

I'm sorry if this seems unnecessarily complicated, but most TV sets today have plenty of inputs for all these things, and usually you just plug in the connecting cables and go. But with older sets or sets that don't offer the inputs, you need to go through these shenanigans. But once you have the parts hooked up, it's not too bad.

Hope this helps, and thanks for using Fixya!

I connect the cable,it doesnt show anything!I try the auto channel search for both cable and antenna,it doesnt find any channel at all!it says-no signal..-rca 20inch sdtv truflat.dual combo with dvd player...


I assume you tried the cable on a working TV to make sure there is a signal on the cable line and that the cable terminal is OK. See if you can control the input selector and set it up for RF or TV reception. If OK, try to tune in channels manually or in auto mode. Do this in programming mode. If you notice any noise on the screen, this means the source selector circuit is OK. If there is no noise, the source selector may not be latched to the RF circuit output. Try to feel the terminal at the back of the TV set. If it feels like it moves when pressure is applied in various directions, chances are the solder connection for the terminal onto the circuit board may be faulty. Resoldering them would be easy for DIY enthusiasts. If it isn't the culprit, try the DVD. If it works fine, then the video circuits must be ok. The trouble could be from the video source selector circuit backwards to the RF block. Usually an IC senses the power condition of the DVD player. If it senses that the player is ON, the IC latches on the signal coming from the DVD player. See if there i a separate power button for the DVD. More later, please post a feedback

Can not make the instalation betwen my tv and my dvd player


Most DVD players today have only RCA jacks for video and audio outputs, and don't have RF (channel 3 or 4) outputs. If your TV doesn't have AV input jacks (either too old or just not supplied on your model) you can't connect the DVD player directly. You'll need to get an RF converter to make the connection.

An RF converter costs about $15 and you'll find them where you can buy TVs. The converter takes the video and audio signals from the DVD player and creates a channel 3 or 4 output signal to your TV. If you don't have the cables already, make sure to get them too. You need a "dubbing cable" (RCA plugs on the ends, usually color-coded red, white and yellow) to connect the DVD player to the converter input jacks and an RF cable with "F connectors" on the ends for the output to the TV. Often the dubbing cable comes with a new DVD player, and the RF cable with the RF converter.

If this takes care of your connection troubles, please take a moment to give my solution a good rating. If I've missed something and can be of more help, please post a followup comment.

YOU HAVE A BAD TUNER OR RF INPUT. IF YOU CONNECT THE CABLE TO THE VCR AND THEN USE THE VIDEO OUTPUT OF THE VCR TO THE VIDEO INPUT OF THE TV YOU CAN USE THE TUNER IN THE VCR TO CHANGE CHANNELS.

Hi,

Appreciate the direct "Ask Me".

Technically, when a TV signal is said to be snowy, it indicates that the incoming RF signal is weak; on the other hand, when a TV signal has static, this refers to electrical noise that goes with the TV signal.

Having said that, then to your concern:
  • for snowy signal, it is the cable providers problem. They have to change where your incoming cable is tapped from, check/replace the feedin cable itself or worst case scenario, replace the line amp/distribution amplifier feeding your cable input;
  • for static noise, what is required is to check possible sources which could include (but not be limited to) electronic ballasts of florescent lamps, electric fans, hair dryers, shavers, wireless phones, computers and others.
Additionally, you may want to check if you have any RF producing devices attached to the TV such as VCRs, DVDs, game consoles. You can try unplugging them when not in use.

Worst case scenario is the tuner block of the TV is getting weak (unlikely but possibly). You can try rewiring the cable to feed first into a VCR, connect the VCR to any of the free Video IN, and select channels through the VCR. If significant improvement, then you have just confirmed an internal fault with the TV tuner, if problem persists, then the static/noise/low RF is caused by something else.

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.

Tuner Problems


OK the tuner may be causing these problems, however first I would like you to go to your menu and set the RF pickup to antenna (This will allow analog channels) then come out of the memu and select a channel in the analog range channel 4, 7, or 9 try to tune in these channels. If this fails then you may have tuner problems the only way to be sure is to use a RF signal generator to send RF through the tuner and see if the video and audio being carried on that signal comes through. Sometimes the Internet connect gets messed up when the TV does not have the proper RF filters this may be your case. Try this use a Cable tv set top box and just set your TV to channel 3 for cable. This should Isolate the TV from the Internet cable modem and provide the signal needed by the TV.

Multiple video inputs


Unfortunately, you cannot use the connectors at the same time. The S-Video connector overrides the standard video connector. This is why they share common audio left/right inputs. If you could use them separately, they would each have their own set of audio inputs. (S-Video does not carry audio signals on the cable.) I'm assuming that you are connecting your Satellite as an input to your VCR, and then your VCR to the TV via a video connection. The VCR passes the satellite signal through unless you are watching a tape, then it overrides the dish signal. You have a few choices here: 1. You can connect the coaxial (RF) output from the VCR to the TV, and watch the satellite and VCR on channel 3 (or 4). You can then connect the DVD via S-Video, and watch it on "video". This is the simplest solution, and provides the best picture quality for the DVD (with this TV), but lower quality for the dish and VCR. 2. You can connect the DVD player via RF (if it supports that), watch the DVD on channel 3, and connect the VCR via video. This will make the DVD picture quality terrible. 3. You can replace the VCR with a combo DVD/VCR unit. You can then connect the S-Video out from the combo unit to the TV. This is a more expensive solution. 4. You can replace the TV with a model that includes more inputs. This is the most expensive solution, but will allow you to watch your DVD over component cables (very high quality) and VCR and dish over S-Video. Ironically, the obvious choice, connecting the DVD as an input to the VCR (as a pass-through) simply WON'T WORK. The signal put out by the DVD player is "copy protected" (using a system called MacroVision) which the VCR will refuse to play, even as a pass-though. Best of luck with this. Given that you are trying to make this all work without replacing equipment, I recommend option #1, until you decide to break down and buy a shiny new HDTV. They are coming down in price every week, but only you can decide when the time is right.
