I have a geforce fx 5200 128mb video card in my msi-ms7211 model pc and 2nd tv is fuzzy as heck?

My pc is a pc3200 msi- ms-7200 with the geforce fx5200 video card and i've tried buying a 4-pin cord for the video out on the card and i ran the rca jacks on the other end to my tv and the screen is really, really bad, you can tell there is the same picture that's on the desktop, but it looks very scrambly and bad, i tried everything. i even installed the drivers from the msi and nvidia websites, nothing is working? i set the tv as dual view and as clone. i right click on my desktop and go to settings and switched resolutions and hertz? i even checked the box extend my windows desktop into this monitor? i hope it's something small? nobody has helped me yet on other site fixes.|||There are some things that would likely make your TV/monitor fuzzy...

1). faulty cables

2). faulty connections in the videocard

and lastly

3) If your tv is one of those with normal definition (the old ones) it couldn't handle high resolutions and would project it in its own size making the screen really fuzzy and with text unreadable...
