7pin S-video to Female RCA ---> Both side Male RCA ---> TV RCA input

Insprion 1520
Geforce 8600M
Vista 32-bit

When I connect my 7 Pin S-video to RCA which will be the yellow cable , using an old TV which only have RCA input.I got nothing from the tv where it shimmer along.I did press Fn+F8 and it show 'no external monitor display is attached".

Right click properties -> display , the second monitor doesn't show any tv output.It seems like it doesn't recognize the TV as secondary display.I went through Dell support and I found this.

Do I really need to update my BIOS and Graphic card driver in order to work ?

Please guide me for those who has successfully connect to the TV.

 

bump , anyone ?

 

I am not sure you got the right cable. I got a dongle from Dell that has composite, S-video, and digital sound port that works perfectly. Anyway, try to change the order of turning things on. It seems you laptop is not sensing a TV connection. You may need to hook up the cables, turn on the TV, and then your laptop to see if it works this way. Mine is Vostro 1400, so it may be different from yours.

 

The cable was just 6 inch , the end is 7-pin Male and the other end is Female Yellow RCA.
This is the cable I use http://image.compusa.com/prodimages/27/2648d36b-b143-4fc2-8522-17396b08eea3.gif

Do I really need to have Dell's S-Video to TV-Composite Cable ?

Any 1520 user successfully connect to the TV without Dell composite ?

 

That cable should work as well because it will make use of only the required 4-pins of S-Video and convert the signal to Composite.... I dont know why it doesnt

 

Ash Hi Fi Zone* did you try it before ? I still wondering why it doesn't pick up any signal.The Fn+F8 shows "no external monitor display is attached"

What's your bios and Graphic card version ?

 

Go try to change the order of turning on things as I suggested above. This usually solve the TV-out problem. I believe all the current laptops have the BIOS supporting video out already.
Nevertheless, I have a cable from ATi (I think) that convert S-video to S+composite which does not work on my laptop. So that may depend on the wiring of the cable.

 

Did that a few times, it doesn't connect.I just tested with a 4-pin s-video and the TV doesn't shimmer at all just by staying black.Still no help.

Anyone had 1520 able connect to the TV using s-video cable rather than Dell's composite ? how many pin did you use ?

 

Svid>RCA doesn't always work. you should check the cable against another setup, like another tv or an LCD to make sure it works.

i also doubt it's a driver or BIOS issue.

most likely the cable.

 

So you do have a TV with S-video input. Then it would be easier to diagnose the problem since you may just use a regular 4-pin S-video cable.
Without connecting to the TV, the Fn-F8 would not do anything. If you have the cable connected, TV-turned on, and then your laptop and yet cannot switch to TV-out with Fn-F8, there is something wrong with your TV out port. What video interface and driver are you using?
The 1520 BIOS (any version) should be fine as they are all from this year.

 

I have a brand new up to date compaq laptop I just bought, as with the purchase i picked up SVGA to RGB cable to run from my monitor input to the HD slots in the back of my tv. I run windows vista and it recognized a second output, so I selected to run a mirrored image of my second output. Now whenever I turn both on and select to use my input component on my tv, I get a blue snowish screen and don't know what I'm doing wrong. Anyone have any ideas?

 

I got a brand new laptop and I picked up a SVGA to RGB cable to run from my pc's monitor slot to the HD plugs in the back of my tv. When i try to go to display settings and switch it over, all i get is a blueish snow screen. Not sure what I'm doing wrong, anybody got any ideas??

 

I have this problem as well. I know it has nothing to do with the s-video cable I used because it worked fine for a while, but after I did a reformat to my computer, it no longer recongnized the TV as a second display. The thing is though, my laptop would adjust it's resolution settings to match the TV, but the TV would not even display what the laptop is showing. It also made it so my resolution on my laptop was messed up, with extra spaces on the left and right.

I figure it is a video card problem and I am having trouble finding the correct version??

 

Hey Liquidsmoke,
You just make one of the most common mistake. Component and RGB are not the same. It is confusing that they use the same 3 color plugs. The signal pass through VGA cable is RGB which is rarelly used in HDTV. Those on HDTV are component input not RGB. If you look carefully, they are not labelled RGB.

 

I had an old desktop Graphic Card tested and work well 9 pin VIVO.It's just a cake , plug in the cable and it auto detect my tv and resize to its' resolution.
I can't use a 9 pin male svideo cable into a 7 pin input.
It's not the TV problem.

I did mention my TV only have RCA input.My previous reply was tested using a 4-pin svideo Male to Female RCA Yellow.Which means , I done by testing both 4 pin and 7 pin on Dell 1520 notebook.No luck and it still doesn't work.
The 4 pin to RCA shows nothing while the 7 pin will cause my TV shimmer.

Still waiting for someone who did it without any dell composite.Pwnstar , are you using normal svideo to rca cable ?

 

Anyone ? what's the major difference between 4-pin and 7-pin ?
I tested with 4 pin out to RCA but no display on the TV whilst with 7 pin to RCA my TV does shimmer.
It shows that 7 pin to RCA does have a response compare to 4 pin :confused2:

Please anyone with 1520 successfully output , please share your configuration such as cable , setting , bios version and Geforce 8600m driver version.
Thank you

 

I believe the 7-pin Svideo connector can output more information than a regular 4-pin svideo can.... And the SPDIF audio that can be obtained is due to these extra 3-pins.... And I think you should not call it plainly as RCA as it can be confused for Component RCA as well while actually you are meaning Composite RCA....

 

Which means both 7 pin svideo and 4 pin svideo can still output to the TV ?
Well I'm sure I was talk about composite RCA which will be the Yellow connector.

Right now , still figuring out why it doesn't detect.It's either OS Vista , Graphic card driver , hardware failure or my TV.

Hoping for someone who owns an Insprion 1520 reply here.

 

Yeah they sure can since those 4-pins are mapped to the 4-pins of the 7-pin connector as well..... But I'm not sure why it is not working though....

 

Did you try using composite yellow RCA ? Did it work ? What's your graphic card driver and Bios version ?

 

I just did a 4 pin S-video to 4 pin S-video. Worked fine on my TV.
My video driver is v162.62
Haven't done a BIOS update.

I haven't tried going from S to composite, but I think I have an idea on what the problem might be on the 7-pin to rca:

Dell 7 pin S-Video out can output standar S-video, component, and composite. Plugging a 7 pin S-Video to single rca connector may not work because then you would be combining both composite and component, and your TV will be like 'what the heck', and all it will be able to do is display some static noise.

So the obvious choice is to get a 4-pin S-Video to rca cable. I don't know why it wouldn't work on some folks here, but have you tried playing with the 'input' button on the remote of your TV?
Try every input mode, and for every one of them, hit fn+F8.

 

Of course the 4pin S-video cable direct connection should work without problem. The component output use the same port but a different adapter cable. There are 2 other adapter cable for the TV-out port. One is the S-video, composite, and digital audio in one dongle. The other one is an S-video to composite adapter cable. The OP got a generic one that is similar to the OEM one of the latter kind, but it may or may not be compatible depending on the wiring. The OEM S-video to Composite cable is available for ~$2.50 plus shipping on the web. However, it may not be compatible with some Dell laptop. For mine Vostro 1400 (same as Inspiron 1420), only the first 2 kinds (the component and the S/Composite/SPIF) are mentioned in the manual to be used with the TV-out port.
