No S-Video input signal

Go to Amazon and for $10 solve the problem

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.

Since you didn't give the model SuperScan TV, I am going to speculate that your TV has composite video input only; like the 19TVD3S that I know. If your laptop has a VGA port, you will need a VGA to composite video converter. See http://www.monoprice.com/products/product.asp?c_id=101&cp_id=10114&cs_id=1011407&p_id=4724&seq=1&format=2 . Other stores have similar items. You can't use a VGA to composite video cable; these cables are for connecting to projectors that read the computer's RGB signal.

Other converters are available for VGA to component video. If your laptop has an HDMI output, then a HDMI to component video converter would be a good idea. (A few rare computers came with TV out; then you just need the correct adapter for the port to composite or component video.)
Next you may need to enable the external video output in your BIOS. The port can be disabled for power-saving. In that case, look at the splash screen as your computer boots up. It will tell you (in a brief blink) if you need to press Esc, Del, F1, F2 or another key to access the BIOS. Press the key repeatedly after turning on the computer (after shutting down); if you miss the timing, turn off the computer and try again. I've missed the timing several times.
Once the port is active, make sure that the TV is on and set to the video input. Then turn on the computer. If you have Windows, you will have to choose the screen to use for your display. For most newer versions of Windows, right click on a portion of the desktop (somewhere with no icons or running programs). Select Screen Resolution or a similar line. Then you can select using the monitors as duplicate monitors, extended monitors or Monitor 1 or Monitor 2 only.
I hope this helps.

(If your TV has newer inputs, use the VGA port if available. The HDMI port for many TVs do not always interpret a computer HDMI signal correctly.)

Try searching google for your monitors model name and "driver"

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.

the Flat Screen TV if has, a HDMI input, also has VGA Input.

You must choose :HDMI or VGA, if HDMI The VGA board must Have HDMI Connector, and you connect a HDMI cable to the TV.

The HDMI is a digital signal input/output, VGA is Analog Signal. You must have Signal Converter if you Use the 2 signals

If the computer was connected to the Magnavox using the VGA connector you will not hear sound through the Magnavox, as the VGA connector is a video signal only. Unless you use the HDMI connector, which carries both video and audio, you may not have sound. Verify the back of the Magnavox to see if there are any audio inputs from the PC that may work alongside the VGA connection. Most televisions with a VGA connector do not have this feature as the VGA is strictly for video signal and not sound.

Composite video are yellow RCA jacks and are made for analog signals of standard definition video. If you are connecting a digital source or a high definition output, it may be beyond the capabilities of the projector. You may be able to find a VGA to composite adapter if you laptop or whatever has a VGA output port. VGA is along the same lines of composite (analog, standard definition).

Hi. The best way to hook your computers display to your LCD screen will be to use the VGA input socket. If your video card can support both S-video input and VGA, you can use either one but, the VGA is best for optimal resolution. This is the easy way to do this. Step one, connect the VGA cable to the computers video card and then, run the other end of this same cable to the VGA input slot on the LCD screen.Step 2, next you will make sure that the LCD's input selection is selected to show what is being transferred from the CPU video card by using the input button on the lcd remote control. The lcd(your tv) should be on VGA or PC input signal. Step 3, now, you Will have to also make sure that your video card is set to transfer this signal as well by pulling up your video cards software window and switch to the proper options. once this is done, you should get a signal. Be sure to use the VGA input/output ports on both the lcd television and your cpu for optimal transfer of the video stream. Here is a pic of your back panel. use the input port labeled I for good PC input quality.

Hi there

As far as I know this specific model requires comes out with a convertor box - are you using it ?
