S-Video Connection between Laptop and TV only blurry when laptop plugged in

This is a very weird problem and I'd appreciate anyone's help. I have an Acer Extensa 4620-4648 that I'm trying to connect to a Philips HDTV using the S-Video connection. My problem is that the display on the TV is sometimes totally clear, but other times it is distorted and covered with wavy black lines. I've noticed that the lines only appear when the laptop is plugged in. Also, I've noticed that the distortion occurs as soon as the metal partof the power cord touches the inside of the jack in the computer, evenbefore it is fully "plugged in" (I can even trigger the distortion by just lightly touching the metal part of the cord to the jack).

I have tried connecting the S-Video to the TV both before and after the computer has started up. I have also tried connecting both with and without the computer being plugged in. Either way the pattern is the same: clear when running on batteries, distorted when plugged in.

I can use it without having it plugged in for short periods (< 2 hours), but I'd like to use the TV to watch movies, etc... Anyone have any thoughts?

You may have a combination problem of a bad shield in your S-Video cable and a floating ground on your laptop that doesn't interfere when operating from batteries.

I would first replace the cable and if the problem is still present, you may need a new adaptor for your laptop.
The bars/lines you describe come from a slight difference in the synchronization of the TV signal and 60 cycle AC being in the wrong place. That small difference in frequency is causing your video to be modulated.
Before modern stuff, this used to only case 'hum' in the audio.

Rgb connection stopped working on laptop


Instructions
    • 1 Decide if you want to watch the television on your computer or use the TV as a larger monitor. If you want to view the contents of the TV on your laptop, you need a video card connected to to the computer. These cards can either be inserted through the express PCI card slot on the laptop, or via USB cable. Make sure the video tuner card supports component video.
    • 2 Connect the DVI-to-component cable into the DVI port if you want to use the TV as a large monitor for your laptop. However, if you have a VGA port, plug the VGA-to-component cable into the VGA port.
    • 3 Plug the RGB component cables into the component side of the DVI- or VGA-to-component cable. If you want to watch the TV on your computer, insert the RGB cables into the TV video card.
    • 4 Plug the other end of the RGB component cables into the TV. If you are using the TV as a monitor, plug the cables into the "Component In" ports. However, if you are sending the TV signal to the computer, plug the cables into the "Component Out" port (the other end of the DVI- or VGA-to-component cable that you connected to your computer in Step 2).
    • 5 Power on the TV. If you are using the TV as a computer monitor, press the "Video" button until "Component Video" appears on the screen. If you are watching TV on your computer, launch the television viewing software that came with the TV tuner card. You can now see the contents of the TV on your computer.

I have a Dell computer that runs Windows Vista and I want to hook it up to use my TV as a monitor to watch a webcast. Please advise.


The first step is to inspect both your laptop and TV and identify the connections, easily located on the back of either component. There are five basic types of jacks, or ports involved:
*Composite/phono plug (RCA)
*S-Video
*Video graphics array (VGA)
*Digital video interface (DVI)
*High-definition multimedia interface (HDMI)
*An RCA connector, sometimes called a phono connector, is used for analog audio and video components. Three round, colored sockets are standard — left audio is white, right audio is red, and composite video is yellow. These are standard jacks on older TV’s and laptops. A three-prong cable, readily available at any computer or electronics, is the easiest way to make an RCA laptop to TV connection.
*S-Video, or Super-Video, a more advanced analog video connector, uses a four-prong round plug, like those used in TV cable installations. Separate audio cables are the same as for the RCA connector, left audio/white, and right audio/red. S-Video is commonly found on older TV sets and some laptops.
With S-Video on both TV and laptop, connecting a laptop to a TV is a simple matter of a single S-Video cable. If your laptop has a great sound system, you won’t need audio cables, but for better quality you’ll also want audio cables.
RCA to S-Video cable, a special laptop to TV cable, is available when you have RCA jacks on one device and an S-Video port on the other.
*A VGA connector and cable are used to carry analog video signals plus display and graphics data. The VGA is a 15-pin connector commonly found on laptops and other devices. With this port you need a PC-to-TV Convertor to connect laptop to TV. You simply plug the VGA cable from the source into the convertor, and use an S-Video or RCA cable out to the TV. The converter is USB powered, so there’s no external power adapter to carry around, making this laptop to TV connection entirely portable.
*A DVI port is rectangular with 24 pins arranged in three horizontal rows of eight pins for digital video; separate RCA analog audio cables fit into white and red plugs. DVI ports are found on Macintosh laptops; sometimes they are smaller than normal DVI ports and require an adapter, which usually comes with the laptop.
*The HDMI port, one-half the size of the DVI port, is also rectangular with 19 pins. It provides digital audio in addition to digital video, despite it’s smaller size, for a complete TV to laptop connection. These ports are found on new HDTVs, and sometimes there are two or more. TVs with HDMI ports are the only ones that do not require additional audio cables.
TV’s with a single digital port labeled HDMI/DVI require only one cable when the source is another HDMI component. But when source is a DVI laptop, you need a DVI-to-HDMI cable for the video and a separate pair of RCA analog stereo cables.
NOTE: Whenever ports do not match, you can by adaptors and/or cables to make any connection.

Input jacks in Sharp 25J-M100/ Pc to Tv cable


You can purchase an s-video to composite video connector to view your Dell computer's television output on your sharp CRT television, though the image will be a bit blurry because of the connection and CRT technology limitations, though streaming video probably can be seen just fine. An example of an s-video to composite video connector can be found here: http://www.svideo.com/svideorca.html
but you probably can find a cheaper priced unit somewhere else, maybe even at radioshack.
I hope this helps!

My Dell Inspiron 1521 stopped working and the screen went blank. I tried to reboot, but no luck. I removed the battery and changed to a 9-cell, but that also does not do anything. I have it plugged into...


It sounds like either the Video Card or the LCD has failed.

Have you tried connecting an external monitor and see if you get any video?

also, try running PSA diagnostics. Hold the Fn Key while pressing power button, to start the diags, see if you get any video. If you get no video after 50 seconds, you should hear a beep, press N and see if a Set of solid color screens comes on the LCD. If it does, then issue is the video card or cable connection. You can try reseating the video cable to the video card (Connection is under keyboard)

Want to connect my Sony vaio VGN-A250 to Sharp 19'' LCD TV


Your laptop will have a VGA output or possibly a S-video out. For the VGA you'll need a standard VGA cable. Plug the cable in to your laptop and the PC input of your TV. If your TV does not have PC input it may have a DVI input. IF it does you can use a VGA/DVI adapter to plug it in. If it doesn't have a DVI input you can use the S-Video output on your laptop with a standard S-video cable. After the connection to your TV is made you will have to toggle alternate display by pressing and holding your [Fn] key and pressing F4, or F5, or another F# key. It's the one that looks like a TV screen. Press once to turn on output, press again to turn off your laptop screen, press again to go back to laptop screen only

Why wont my laptop run on my lcd hdtv made by Vizio


You must redirect the video output from the laptop screen to the TV.
It usually takes a keystroke combination, depending on your laptop it is hold the FN(function) key(lower left on keyboard close to the Ctrl and Alt key) and press on of the F1-F12 keys on top of keyboard.
You can try one combination at a time until it switches. Your FN key may have a Flying Windows icon and the F1-F12 key may have a TV icon on it.
Let me know if you get it working and please rate this solution.

Connecting my HP Pavillion DV9500 laptop to my Samsung PS-42Q96HD


Sound more like your problem is with the connection to the TV. Make sure the connection at the TV is to an 'input' connector and not 'output'. Also, from the TV menu, if you can select the output the laptop is using make sure the sound is stereo an not 5.1 or 7.1 or something to that effect. All other connections seem to be in good shape. Good luck.
