Question about Apple iMac G4 Desktop

but when i plug in a DVI connector (not connected to any device) it MOSTLY goes away.... when i un-plug it, it;s better for a minute or 2 and the returns...
Your logic board and graphics chips are fine. But it's possible that some of the settings have been corrupted which is causing the problem. To rectify this, first of all in the Display settings (in the system preferences) click the button to 'Detect Displays'. If that doesn't help it you just need to reset the PRAM. Here are the links to the Apple site for instructions on how to do this:
If the computer is a PowerBook (as inferred by 'titanium' in your subject heading) rather than an iMac then you can also reset the PMU:
That should hopefully sort it out. By the way, just to help us out when giving a diagnosis be sure to put the item in the correct category (Titanium g4 isn't an iMac) just to avoid confusion.
All the best
