My tv jvc av 27530 has ablue screen and un able to operate by remote or manually so could you help me please?

many of the late model tvs with a crt (picture tube) would go to a blue screen when there is not signal from the cable or antenna so you don't get the irritating white noise and black and white dots running all over the screen, (called the raster), so probably you aren't getting a signal to the tuner. check your connection from the cable/antenna.

KP-61HS30 has sound but no video

1) the problem you have is lack of raster , the problem in tv has 4 phase 1) raster 2) picture 3) synch 4) sound.
2) test the power supply , check the horizontal output +125vdc ,vertical output from +80vdc, +al other circuit +12vdc, if there are missing fix it, see the diagram attached.
3) TEST the signal from tuner,i-f, detector, AGC

I am trying to plug a play station 2 into the rca f19240 and do not see ports for the three colored prongs that I need to conect

Many of RCA's smaller sets didn't come with AV input jacks. They only had a connector for an antenna or cable wire. To use a device like a DVD player or game console with a TV like this, you need an RF modulator. This takes the audio and video signals (those three cables you can't plug in to the TV right now) and creates a signal that the TV can tune in on channel 3 or 4. Unless you replace the TV with one that has AV inputs, the modulator is your only solution.

Sony KV- 20FV12 get no signal on screen. Same cable outlet works on other TV as a test. Cable ON in menu. Auto Set search produces search but still no signal.


If auto search is going on smoothly, and there is no stations on air is memorized, and display no signal, there are tow possibilities. The first one is antenna is not connected properly. Check the antenna connection for firm. The second one is tuner fault. If the tuner inside the tV is faulty, or it does not gets proper voltage to work, this type of fault land display will see on screen. Check if proper voltages are comming to the tuner section in circuit board. If voltages are ok, and still there is no signal display, just check it with external video input. That is, connect it to any dvd or cd with AV connector, and set the TV to AV mode and play a disc. If there is picture, the video side of your TV is OK. If not, Video-chroma-RF jungle IC is faulty, and not the tuner. OK.

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:

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 cant find the av jacks to hook up my dvd player

This model doesn't have any A/V jacks. Many low-end RCA models didn't include any special features. They can only pick up signals over the antenna input. What you'll need to connect your DVD player is an RF converter, which takes the audio and video signals from the player and turns them into a channel 3 or 4 TV signal that the set can pick up.

RF converters aren't hard to find. Radio Shack, Sears and Wal-Mart all say they sell them, and you can certainly find them online. Hooking one up is just a matter of connecting the necessary cable to the player and TV, connecting the converter power and setting the output channel. Then put the TV on that channel and you're set. Unfortunately, this will give you lower picture and sound quality than you get from a TV that allows direct A/V inputs, but it's the only option.

firstly try that tv to a different tv
if this works
then check your tv av connections in side tv
also check cables continuity
if this fails buy a AV/ RF converter, have your AV be connected to a converter, and let your output be RF feed to a tv, RF input, so instead of using AV on your tv you will be using RFchannel mode

DVD input with signal access

IF I understand you correctly, the VCR, Satellite, etc is connected using an RF modulator/coaxial cable wire going into Antenna in

IF this is true, then you have an AV IN port (red, yellow, white) free on the back. Just connect the red, yellow, white from the out of the DVD - you can use 1 or 2 - just remember which one you used; and connect it to the AV IN on the back of the TV.

THEN press ch down on the TV remote until you get to "AV1" - it is below channel 2; double check DVD player to make DVD is playing and voila!
