http://www.amazon.com/gp/product/images/B000FM3EQ0/ref=dp_image_0?ie=UTF8&n=172282&s=electronics

and only got it cuz i thought i could hook it up to my laptop and then connect it to the tv my laptop is a sony vaio vgn-n160g and the tv is a sanyo the tv only has the regular red yellow n white connections along with the blue green and red ones and an hdmi and svideo connections however my laptop has only the vga/monitor port and usb ports....
how does this cable not work like i thought it would?
what do i do?

 

If your TV has component inputs (usually Red, Green and Blue) then that cable should work. Are you sure you set the TV's input to component ? and switched Notebook's video to external display mode ?

 

okay so yea the tv is turnd to the correct input and as for the laptop the only real thing i know what to do would be to go under display settings and make shure that box is checked that says extend my windows to this monitor or what ever... other then that i have no clue could it b a driver?

 

Yes - you can use Component cables (red, green, blue) to connect Yellow/Red/White jacks. You can SOMETIMES do the opposite, but not always.

"Component Cables" have been around for years for standard def. While cheap standard def cables will appear to work on a HDTV - there can be ghosting and loss of fine focus with the higher frequency HD video signals.

THE RULES

All video cables must be made with 75 ohm coax. The "Yellow" cable in a set and the Red/Green/Blue cables are all video cables.

The red/white cables in a set are sometimes just 2 more video cables, but sometimes not. The Radio Shack set uses different cables for the red/white wires so this is no longer a cheap way to get a component cable.

THE FREQUENCIES

Standard Def (480i) : 4 Mhz max
Progressive (480p) : 12 Mhz max
HD Video (720, 1080) 35 Mhz max


See how much higher frequency the HD signals are? This is why you dont want generic 'component' cables for a HD system.

Read the package to make sure the component cables either say "HD Rated" or bandwidth of 90 Mhz or more.

 

Sorry, just read your post again. The cable should work with the RGB connections on your tv. Maybe you should go into your display settings and look for external monitor settings. Possibly in the BIOS to enable them too?
Good luck.

 

ive messed with the external monitor settings thing under display settings and nothing how would going through bios enable it? and how would i go about that?

 

NO, Yellow/Red/White jacks are for composite video NOT component video. Out of the three Yellow/Red/White jacks only Yellow is for video, other two : Red and white are for audio. Component video on the other hand is completely different. You have to connect those cables to the Red, Green, Blue component inputs of your TV.

 

You have not connected it properly thats the reason you are not getting it....

 

yes i have its all connected correctly im not that dumb... still no picture

 

What is your TV ? Is it a new Plasma/LCD or an old rear projection / CRT ?

EDIT :
I haven’t personally connected a TV over Component, but they should work. However, normal VGA and RGB or components are little different since pure RGB line of a VGA output it doesn’t have a sync signal. But I think those cable are meant for a video signal Synced on the green channel, but I’m not sure if your laptop can output that kind of a signal. If it doesn’t, then you’ll need a signal converter.
To get high definition video over VGA you’ll need a VGA to Component transcoder; they can be a little expensive, but here is a 720p transcoder I found on eBay for less than $100. But if you only want standard definition quality video then you can use a cheap VGA to TV converter box. I have used the later type to hook up an old CRT some time back.

 

You'll have to use an active converter.

Just look up for VGA, composite, component, ... in Wikipedia and you'll see that it won't work with a simple cable you try to use. The different signals are similar but still different.

To your TV:
Worst quality: Yellow (Video, Composite)
Bad quality: S-Video
Normal or Good (Don't know how it looks with a PC connected): Blue, Green, Red (component)
best quality: HDMI

Audio: Red (right channel), White (left channel)



So the best option is to buy:
for video:
a VGA to DVI converter like the Aten VC160 and buy a DVI to HDMI cable

for audio:
a simple TRS connector (stereo plug) to RCA connector (Cinch connector) cable

With those 3 parts everything will work in good quality.
A simple passive cable for the video part won't.


Other active VGA to ... converters will also work, but you'll have to find a good one, and often they also cost more than maybe 50USD.
All I know is that the Aten works, how well other work or what converter work , I don't know.
