Question about Symphonic ST420FF 20" TV

1 Answer

Cannot connect the coverter box

The older TV has only an antenna connection on the back. Tried to connect converter box through a DVD player and it worked, using the red, yellow and white wires through the DVD player. Had to disconnect it, and haven't been able to get it connected again so that it works. Straight converter box to TV connection won't work.

When you have your converter box hooked directly with coax to your tv, is your antenna then plugged into your converter box in the "antenna in" port? What do you mean by it doesn't work? Does it say no signal? If so, you just need a stronger antenna. If not, you may have a defective box, bring it back to the place you got it and see if they can help.

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!

Hooking up a convertor , when i have a vcr, dvd player


You can hook it up through the antennae system. Keep your dvr connected to the tv the way you had it. Hook up your TV rabbit ears antennae to the converter box in the connection on the left side of the box. Then hook up the antennae lead from the converter box to your TV on the right side connector. The only thing I'm wondering is, do you get stereo sound this way and does anyone know how to get it without hooking up the separate audio and video plugs? There aren't enough connections on the tv to hook up both sets.

Receive one channel with Coverter Box


Make sure those 6 channels are also being broadcast in Digital format also, otherwise your converter box won't have a digital signal to convert for your TV. The switchover date is early next year I believe.

Can't get my DVD player to work...


Your GE TV most likely doesn't have anything but a antenna input on it? If that the case to connect a DVD player you must purchase a RF modulator to convert the video and audio output of a DVD player to a channel 3 or 4 output. Here is a link for one at Radio Shack.
