TV-Out screen colours in a rotation

Specs: Vista, xp pro too, p4 2.8 gig 800fsb, 1

After 1 week of not using my tv out, I went to use it but now the screen flashes between orange, lilac, Grey and normal, twice in a second. This also happens on the windows XP boot screen too.

I have tried installing new drivers and old drivers too(used a driver cleaner) with no success. I have changes all the leads and adapters assocoiated with the TV out side of things. Checked all settings tv side like pal/ntsc/auto to no avail. Pretty much exhausted everything I can think of.

I'm guessing the graphics card ATI 9600xt is at fault but games are still playing fine on it so thought I'd ask here before trying to track down a replacement Graphics card as someone may have experienced this or have an idea of how to fix it.

Hmm,I guess so...

if that problem never occurs on the laptop screen, I would logically have to say the external monitor is faulty somewhere, or the signal cable between laptop & monitor may need replacing.

Its seems to be the TV acting up but for some reason my cable TV box works fine and shows no symptoms remotely regarding whats happening.

I tested with my ps2 that I had boxed up and it shows the same thing as the TV out does with the rotational colours so I'm confused on whats happening as you'd expect it to happen on Cable too, hence, why I never suspected the TV at all in the Beggining.

Hmm, Guess I need too play around and hope to get it working but I'm thinking TV is faulty in some way.

Hmm,I guess so...

I'm assuming this is a desktop computer.
Most laptops DO NOT have a video CARD - the video adapter is usually built into the mboard and cannot be removed

The computer video output is processed through a chip on the video adapter to produce the TV-out signal, to conform to legacy TV standards, at a vertical refesh rate of either 50 Hz (e.g. PAL or Secam standards) or 60 Hz (North American standards).

Make sure the card is seated all the way down in it's slot.
Try removing the card, wiping off it's contacts, installing it again.

If that doesn't help, you may have damaged the card's circuits.

When you have an ATX family computer, you MUST remove the AC power to the case / power supply whenever you are going to be plugging in or unplugging the video card or any other card, or the ram, or the wiring connections - there are places on the mboard that are always powered as long as the power supply is receiving live AC power, including some of the contacts in slots.
Video cards are easily damaged if you didn't do that. AGP video cards are especially easily damaged because the AGP slot and the card have two vertical rows of horizontally staggered sets of contacts. It's also important for the video card, especially an AGP video card, to always be fastened down at it's bracket before you try booting the computer.
