Is this a video card problem?

Computer G4 DP 1.25 MDD
Video Card Radeon 9800 Mac Pro
Running latest version of 10.4
No new hardware or software

It started this morning so I didn't have a lot of time to play with it. I did check that the card was properly seated and that cables were connected.

Lines appear on my main display and a TV driven by the S-video feed. See attached picture

What is interesting is that lines don't appear on new windows and if I change the desktop pattern it goes away. For how long I don't know.

I suspect a video card problem. If it is should I just have the card repaired or should I buy a new video card.

Do you have a cell phone or speaker by your display. This will cause interference.

Yes, my iPhone was syncing... I hope that's all it is.

My nextel used to do the same thing when it rang. I hope that this is the same case for you..

Unfortunately I still have the problem with even with my iPhone stored well away from my G4 tower. Looks like I need a new video card.

Apple Hardware test from DVD will confirm this.

When's the last time you opened your case? The cooling fan on your video card may be clogged with dust so the VPU is overheating. Take a look and bring some compressed air!

That is most likely a bad video card. Check the cooling fan on the video card; the video card could be overheating or just a bad card. If the fan is bad, you can replace the fan with the old 486 cpu cooling fan or chipset cooling fan.
