Windows 7: Connecting to a Projector

Connecting to a Projector

Here is my problem. I hope this is the correct forum.
I have a HP Paviion dv1464dx Laptop running Window 7 Home that I need to connect to a projector that has only an Svideo input. The laptop has no Svdeo output, only a VGA jack for connecting to an external monitot. It works. I have an VGA to Svideo adapter (the inexpensive 'Y' type) that I connect to the laptop's VGA output and then connect its Svideo cable to one of the Svideo inputs on my TV. Windows 7 detects the TV and allows me to turn Presentation on. The TV accepts Svideo input just fine from my Cox cable box. However, with the laptop connected as above I keep getting a 'No Signal' message from the TV.
My system specs don't reflect the laptop but it has a Mobile Intel 4 Series Express Chip set adapter which, according to the specs, does support TV Out. Use of Fn+F4 doesn't yield a picture on the TV. I am beginning to think something is inhibiting the TV Out feature of the adapter. Could it be Windows 7 or maybe because HP hardwired it out?
Is there anyone here who has successfully used the 'Y' type VGA to Svideo adapter? If so how did you do it?
Will I have to buy one of the more expensive adapters priced at around $70?
The real question is this. Can someone help me get my laptop's VGA output connected to the Svideo input of the projector?
I will really appreciate help.

Thank you.

Problem solved!

I examined the pin out of the laptop's VGA and the pin in/out's of the
adapter. Pin 2 (Green) of the VGA adapter connected the Chroma pin of the S-video and pin 3 (Blue) connected to the Luma. This was true for two other so called adapters.

How can that be expected to produce a signal the projector can use at its S-video input?

What possible use does this type of so called adapter have?

Anyway, I got hold of a real live VGA to S-video converter and all is well even though my pocket book is a little slimmer.
