You need to set the computer to display on another monitor. You don't say what kind of compture you are trying to hook up, but generally if you right click on your screen and then click either "settings" if XP or "screen resolution" if Windows 7 you can find an option to use the tv as a monitor. most laptops will have the option to "display on projector" option. These alll vary with each computer model, but you have to tell the computer to display on your tv, most won't do it automatically

Dell 2407 Can't get rid of "No S-video input signal" message on screen. How do I get rid of this?


Your S-Video connection is referring to a round plug for a TV input signal. Most computers will not have this connection unless you have a TV based video card. If your using a TV 'monitor' as your computer's video device, their will either be a button on the monitor or your remote to allow you to choose the input signal. If you are using a VGA or HDMI or DVI cable as the connector between the two devices, most likely, the light is referring to one of these, as its video source. You will need to match the cable & monitor source detected to get a usable picture output.

Good luck.
Toby.

When tv is turned on, screen shows white w/ blue logo, then shows "VGA" and "no signal" on a blue screen. After a minute it turns off. We cannot get a picture. We have a Time Warner...


Right now the TV is set to accept the video signal from PC through the VGA port so when it does not see the video signal from the VGA port, the TV will go into shutdown or standby mode. You need to change the input to be where the cable box is connected to using INPUT or SOURCE button on the remote.
What kind of connection are you using to make the connection between the TV and the cable box?
Please clarify. Make and model of the TV?

I have a HP m7570n. How do I use a flat screen tv as a monitor


This depends on the TV's available inputs. The Pavilion m7570n has only a VGA output in the standard configuration.

Thus if the TV has a VGA port, turn off the computer and the TV. Then connect a standard VGA (RGB or D-sub 15-pin) m/m cable between the computer and the TV. To use the TV speakers, connect a 3.5 mm audio patch cable between the computers Line-out (green speaker port) to the VGA audio in. Turn on the TV and set the input to VGA (with the Source or Input button on the remote or the TV). Then turn on the computer. Windows XP should find the correct resolution to work with the TV. (If you turn on the TV after turning on the computer, you may get an unsupported signal. Press Ctrl-Alt-Del twice to restart the computer.) If it doesn't work, you may need to connect a different monitor and set the computer to a low resolution before connecting the TV and the computer.

If the TV only has composite or component video inputs, you will need a VGA to video converter (http://www.svideo.com/pctocomponent.html for example). A VGA to component cable will not work; those are for projectors that read an RGB input. TVs interpret YPbPr.

If you have added a video graphics card, you may have an HDMI and/or DVI port(s) on the card. In that case, check the specs of the TV. Some TVs will support HDMI or DVI-HDMI inputs from a computer. Others will not (since computer video signals are not the same as the signal from a set-top box). If you use a DVI-HDMI connector, make sure to use the HDMI port labeled for DVI and connect the audio cable as with the VGA connection. If you use an HDMI connection, you may need to set the sound properties to that of the HDMI port. (Find the control panel item for sound (under Hardware) and then select Manage Audio Devices. Set the Playback properties. If it doesn't work, use an audio patch cable.) Some TVs have RCA audio inputs for the HDMI-DVI connector. In that case, you will need a female 3.5 mm to RCA M/M adapter (if you use a 3.5 mm patch cable). There is a similar device if you want to use an RCA audio cable. You may need to enable the video ports on the graphics card before swapping monitors.

Some video cards have a TV out. In that case, connect the appropriate connector (should come with the video card). Then connect to the component, composite or S-video input on the TV.

Again turn off the TV and the computer before making any connections.

You will probably need to provide your own cables for must of these connection options.

I hope this helps.

When you turn the television on, the screen is blank except for the letters/words: VGA NO SIGNAL We called our cable company and all their suggestions did not work. Could you...


Are you trying to watch tv or use it for the computer? The input or source selection is on VGA at the moment which is the 15 pin input at the rear and it is expecting your computer to be attached. If you are using it with your computer you need to set the resolution on the computer to match the monitor, if you are not then switch the input to TV or whatever you have connected.
If you want to watch cable then switch the input through all the choices until you see a picture. Make sure the cable box is plugged in and powered on. The source or input button is below the number 9 on the remote, SOURCE: Press to select the signal
source, such as TV, AV, S-Video,
Component 1, Component 2 or VGA.

If you don't have a manual to tell you how to switch inputs you should find one here:

How do i switch my monitor to vga input?


Plug in the VGA cable to the monitor, and to the computer.

The monitor automatically determines which inputs have a valid signal source.

You can also set the monitor's source of video input to VGA, by going to the On Screen Display menu, and the Switch Video Input option.

Here is the User Manual,

Don't forget that the TV source or input needs to be set to "PC". Once that is done turn the netbook OFF, then plug the VGA cable into the netbook and start the computer. The computer screen should automatically show up on the TV.

Samsung LCD TV not receiving PC signal


Check your vga cable. Some cables have only 14 pins, some have all 15. The missing pin is pin 9, in the 15 pin cable it carries 5v from the graphics card to the screen. Without that 5v signal most LCD and Plasma television screens won't recognise a PC input. I had the same problem and only managed to fix it when my girlfriend swapped a cable over for me and as she did so glanced inside and said "it's got a bit missing" The cable that came with your PC most likely only has 14 ins as that is all a monitor screen needs.
You can buy a 15 pin cable at most PC or electronic shops, just check that isdoes have all 15 pins befiore you buy it. The cheap ones are just as good as the expensive ones unless you are buying 20 foot cable. For 6 foot cable the cheap ones are just as good as the expensive ones.
