Question about Sony FD Trinitron WEGA KV-27FV310 27" TV

1 Answer

No signal With the antenna connected to the TV and tuned to a channel, the picture is normal. On the screen is a graphic notice that says "no signal" and the sound is muted. If I change to another channel the picture and sound will start for a few seconds and then the sound will mute as the "no signal" appears on the screen. The picture will remain normal. If I switch to PIP I will get the picture and the sound normal when in the PIP mode. What could be wrong? Maybe I have lost the main tuner? There is a second tuner for PIP. Thank you

How to tune in Channel 60 in a Sony Triniton CRT?

assuming that you can "pick up" channel 60..and that the signal is strong enuff...that is part one..make sure you have a good antenna connection and that the antenna is positioned for maximum pick up, then do the scan mode on the tv via the remote control. it will re scan the channels and if the signal from channel 60 is being picked up strong enough, it will program the channel into your set automatically.

Refer to the manual (free download here). Generally, a blue screen indicates a very low or non-existent signal. This can happen when the antenna is unable to gather enough of a signal from a particular broadcaster, or if an A/V input is selected, but the A/V device is not on or providing a signal. Since you are not seeing channel information when tuning, I suspect that the television is set to display an A/V input instead of the internal tuner.

With a working remote, locate the TV/AV button on the lower left (manual page 3 - item 8). When this button is pressed, you can choose to display signals on the ANT, VIDEO1, VIDEO2 or COMPONENT jacks. The ANT selection chooses the input on the RF jack such as an antenna or cable TV (with or without converter box). If using a cable box, the TV tuner should be set to Ch3 or Ch4 as determined by your cable box. Otherwise, select the VIDEO1, VIDEO2 or COMPONENT input that has the source signals you wish to watch from a cable box, DVD player, etc. that is connected to the rear input jacks. Page 7 of the manual details the connection and remote operation.

I hope this helps!

We want to hook our small Magnavox tv to a rabbit ear antennae to get only local stations. How to do this?

Unless this a new TV with ATSC (digital) tuning built in, you will need a digital adapter for off-the-air reception. Older TV sets have analog tuners, and analog broadcasting ended in June 2009. Wal-Mart and Radio Shack carry the adapters, as do other retailers. Your antenna connects to the adapter, and the adapter sends the converted signal to the TV on channel 3 or 4.

With digital broadcasting, a strong signal is necessary. Unlike the analog days, when a weak signal just meant a fuzzy picture, a weak digital signal will cause pixellation (blockiness) or freezing of the picture, or may not even be detected by the tuner. Depending on how far you are from the station's transmitter, you may find that rabbit-ears may not work too well. You may need an amplified antenna or even one outside to get best performance.

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 can't program my tv to regular antenna channels

You can program to regular (analog) antenna channels. To do so you must use the original remote which has a TV/DTV switch in the top right corner of the remote. Choose the appropriate mode for the type of channel you want to see or scan for. Here is a link to the owners manual and a picture of the remote swithc. The info on the signal switching is on pg.13.

Tv out of foucs

These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

Screen looks like a picture negative, PIP works fine, sound fine

Sony's have dual tuning systems to allow for the separate PIP channel. The common problem on the Sony's is the circuit board and tuning module connections go bad. It is likely that the connections on the board or module were already in the decayed process and moving it just accelerated the issues that were inevitable.

The quick fix is to swap the PIP over to the main picture or to bus the antennae signal to the antennae B terminal thus bypassing the bad tuner module.

The recommended fix action is to have someone with soldering skills to remove the chassis, and locate all the cold and cracked solder joints, especially near the tuning modules. If this does not take care of the problem, the tuning modules will need to be removed for re-soldering on the actual tuner modules.

If none of the above works, then you can always use the audio/video outputs of a cable box or vcr to the a/v jacks of the tv, thus bypassing both tuners in the tv.

Suddenly no sound & no picture overnight: is my TV dead?

If you have static siugnal, sure TV is not dead.

Check the aerial cable, ensure it is well plugged in and getting signal.

If you are using a receiver box, check cables to TV and receiver (freeview, sat, cable etc.), try setting channels on receiver again, if it does not work but you get static, then either the cables or receiver are defective.

Test the TV on standalone , connecting it to an external antenna.
Tune again the channels, and save the preset.
If still no signal then the antenna socket on the TV may be defective.

Try using the TV with a DVD.

If you can watch DVDs, and TV is not keeping channels preset, and you tried all the above, at this point htere may be a fault in the tuner card inside tv.

Call the phone number listed on tv user manual to get support, and eventually repair it.

Sony tv problem

If you are connecting the dish receiver to the standard antenna jack (F connector) on the TV, then the TV must be in TV mode and tuned to channel 3. If you accidently change to another channel then you will get the "no signal" message. If this is the case then simply put the TV back on channel 3. If you are using the RCA jacks (red, white yellow) to connect the dish receiver to the TV, then the TV must be in the VIDEO mode to work properly. If you accidently put the TV in the TV mode, you will get the "no signal" message. If this is the case then simply press the TV/VIDEO button.
