I'll start this off with saying I know next to nothing about macs, now to
the problem.

I have been given this mac to fix after someone decided to install OSX10.2
(Panther ?)
on it without upadating the firmware and then went on to clear the Pram (?)
and it wouldn't boot at all.

After much reading up I have fixed it and installed 0S 9.1 and OSX but the
moniter does 800x600 alright, but 1024x768 will sometimes work but more
often than not I end up with the screen going wavy as if it is not in sync,
the external Vga output works ok at all resolutions.

Has anyone any ideas on how to fix this please

I hope I've made sense and thanks in advance.

Simon.



10.2 was Jaguar, Panther is 10.3.
I don't mean to be unkind, but you've answered your own question in your opening line - "I know next to nothing about Macs..." which says to me you shouldn't be fiddling with it; would you attempt to fix your car without knowing at least the rudiments of motor vehicle maintenance?

And, with the best will in the world, someone who by their own admission doesn't know that much about Macs isn't in much of a position to suggest that the OP take the problem to someone who knows more about Macs when that is exactly what he has tried to do by posting here.

Having said that, I haven't encountered the 'wavy screen' at 1024x768 on the imac DV. The higher resolution is to me extremely flickery. 800x600 is the highest usable on those machines IMHO. However, although 'wavy' does suggest a video card or video driver problem, the external VGA working OK suggests a specific monitor problem.

If it is the latter, then it will very likely cost more to fix than the iMac is worth.

Not a lot of help...
