Power Mac 7200 giving bad picture

[Krimlin]

I'm refurbing a couple Power Macintoshs at work and one of thems giving me a bad picture kind of like the monitor cant handle the resolution. I've tried different monitors low resolutions, trading Vram with the other macs and swapping DIMM ram. When i leave all the Vram out and just try and use the on board Vram I get no picutre at all. Power Macs. Anyone got 5ki115 in it?

Maybe it doesn't like funny spelling?


Seriously, I have not worked on a Mac for some years now, but the symptoms you describe seem somewhat "generic"?

If you boot a PC into safe mode you will get that sort of problem. In NT4 you get a startup option for SVGA or VGA mode. Chose VGA, and you will not get the same resolution as SVGA

I have forgotten the Mac terminologies, but somewhere in startup/settings (BIOS), I suspect that it has been set to use an inferior type of monitor/graphics card/graphics memory, or a smaller amount of graphics memory/share.

Anyways...............you seem to have tried just about everything else

Good Luck

Krimlin: This forum is "MAC security discussions"

What does your fuzzy monitor have to do with security???????

I think you need to be more organized with your questions.

If you describe the system information a little more you will receive better response. It is literally impossible to do anything but guess what your problem is with the info you provided.
