The following thread has a poster saying a conversion circuit is not simple to make, and that the easiest way is probably a new video card which outputs the format you want.

ok.. I got it from first link.. Now, i want to ask that i want to interface my PC CPU with TV and want to use TV as display. So, 6pin connector is enough or full 15pins will be required..?

It's more than likely the vga connector which you get will have all 15 pins. Its shape has to physically match the connector on your computer. However you will solder wires to only 6 of the pins. If it does not display properly then you may need to solder the additional 7 wires (as shown in the second pinout table).

Are you planning to use a crt tv? It will make a fuzzy computer display. I have used a crt type with my laptop's S-video output. I cannot even read most of the text. However it is great when watching videos. The tv is brighter and has a larger screen.

Yes i am going to use CRT TV.

On second link

10 Ground (Sync)

12 SDA
13 Horiz Sync
14 Vert Sync
15 SCL

Where to connect this..?

Now that you mention it, I suppose the extra connections are unnecessary for what you are doing.
They must be for making a VGA cable.
