After I connect my Laptop with 15 pin cable to my Samsung 4 series LCD TV and select PC as "Source" I get both Video and audio signals fine. But the display also indicate 'PC" and "CHECK CABLE CONNECTION". This sign does not disappear. How to get is cleared?

Your Acer laptop has a 15-pin VGA port on the rear. It may also have a S-Video and/or a DVI-D port. Any of these can be used to connect to a television monitor. None of these connections, however, supports the sound portion of the signal. You will therefore require two cables, one for the video, and one for the sound. The sound will be a regular 1/8" stereo jack on the PC side. You will need to look at the TV to see what types of connections it accepts. There may be HDMI, DVI-D, S-Video, or RCA connections. Select a cable which matches the connections for each end for both the audio and video.

There are two options available with this laptop. Unfortunatley you will not be able to produce a High Definition picture, but nether the less it is possible to connect it to a HD TV.
The connections available are;
1x VGA - You will need a VGA Cable (as long as your HD TV has a VGA/PC input) cheapest found on Ebay. There is also a VGA to HDMI cable. Still wont be HD but an alternative to think about.

1x S-Video (TV-Out) - You will need a S-Video Cable (make sure HD TV has this input) also cheapest on Ebay.

Both of these options do not produce audio through them so for this you will need a 3.5mm audio jack to 3.5mm audio jack. Plug one end into your earphone socket on your laptop and the other end into your HD TV PC Audio in socket/Audio in socket. If you have a Cinema/surround system you will need a 3.5mm audio jack to stereo phono, as long as the surround system has an audio input.

Hope this helps. If it does please leave a thumbs up....Thank you.

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.

This is the best solution for your problem as a 40 year experience with wires etc. Go to the source of your cable signal connector . Open it and clean the terminals with emery paper , sand the end of the cable shiny clean from corrosion , get a new barrel connectors with gold terminals if possible lengthen the ends of the cable , insert and tighten good, use thick rg-16 or rg 40 cable with good insulation ends crimped professionally with a crimpier or buy ready made , not from dollar store. Get a gold plated professional splitter if you need one or two , it will cost about 15 or more each . Make the cable runs as short as possible, using the thick good cables. If needed get a signal magnifier. From radio shack or the source etc. Connect them good and tight . Ground the splitters . Problem solved , you will get crystal clear channel 2 to 7 including 3 and 4 . Isolate the TV cable from other cables and power wires. Vitally

had the same issue, called up customer care of samsung and they suggested me to change the cable to D-15 10 series. I was getting the comp o/p on TV but with the "Check Signal Cable" messg with the old VGA cable where some pin is not grounded used for computer to monitor connectivity.
Abhi..

you should be configure the display option , as extended monitor (2nd) output ,

Most common problem is the VGA cable. Make sure you have the 15 pin VGA Monitor cable.

1. Switch off the TV & Notebook
2. Connect the VGA cable to the TV and Notebook.
3. Switch on the Notebook. Set the resolution to 800 x 600 Pixels (Go to Control Panel - Adjust Screen Resolution). Then go to Advanced settings and set 'Screen Refresh rate' as 60 hz in the Monitor tab,
4. Switch on the TV. Go to Source button from the TV remote and select PC as input source. Alternatively, you can go to 'Menu' and select 'PC' as input source. If the connection is made properly, PC option will NOT be GREY anymore.
5. Press Fn + F5, F6, F7 (depending on which Notebook brand you have)

The problem is located in the CABLE, the SAMSUNG LCD need the higher quality cable than others vendors.
Please try it.

Atlast I got some help from the right people (Samsung)! I would like to share it with others facing the same problem:

If you are using the D-sub 15 pin jack (VGA Monitor Cable: make sure its 15 pin and NOT 14 pins), follow these steps:

1. Make sure your TV and computer are off.
2. Using a 15 pin D-sub (standard) video cable, connect the Video Out jack on your computer's video card to the PC In jack on the back of your TV.
3. Using an audio cable with a min-stereo plug on one end and two RCA jacks on the other, connect the Audio Out jack on your computer to the left and right PC Audio In jacks on your TV. (Note: If you have your computer connected to separate speakers, you can skip this step)
4. Switch on the Notebook and Adjust the Resolution (800 x 600 pixels would do). You can go to Control Panel and Adjust the screen resolution. (Keep ‘Screen Refresh rate’ at 60hz in the Monitor Settings)
5. Switch on the TV and try to Select the Source as 'PC' (you can do this by either pressing the 'Source' button several times on your TV remote or go to the Menu - Setup and Select the 'PC' as source there).
6. In most cases, after following the above steps, the TV would start to show 'Auto Adjusting' message and it will start showing your Desk top on the TV. But incase it doesn't work, you can do the following:

a. Mostly the problem lies with the VGA cable. Make sure you have the right one (15 pin) and its securely attached at both ends. If you are not using the right VGA Cable, it means that there is no connection between your TV and Notebook. Your TV will show 'PC' in Grey in the Source Input list (Go to ‘Menu’ from the TV remote).
b. Both your Notebook and TV should be switched off when you are connecting the cable otherwise one of them might have a problem detecting the other one.
c. Try Pressing Fn + F5, F6, F7 (depends on which Notebook brand you are using) on your Notebook several times. At times, you will see some signs that the Notebook and TV are trying to connect. Select 'CRT' from list of displays available to you.

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.
