Weird Monitor Problem Options

[gavinf]

Hi

Can someone help?!?!? Please?!? I have this annoying thing where I switched monitors a while ago, and found when I booted my G4 into 9.2 with the new monitor the startup got about 10% through the bar (before any extension icons) and then flickered twice, then the bar moved a little more, and the screen goes black. Sometimes it won't reboot from the switch from there. Tried another monitor (original monitor gone). No change.

Funny thing is, it boots fine into 10.2 and in Classic, and it boots fine from a CD.

Tried base set of extensions. No change.

I tried an in-place reinstall of 9.1 (couldn't find the 9.2 disk). No change. Reinstalled 10 over that. No change. It's driving me completey bonkers.

Yikes, lepetitmartien, I don't know about holding down the CUDA switch while you're starting up

Done by a technician while trying to restart my G3 after changing the CD. (I managed to start it alone, but I'm a genius

Write an Applescript to set your monitor to 640x480, 65hz, 256 colors, (which any monitor should be able to handle), and stick it in your OS 9 startup items folder. You still won't have any video until the finder loads and the script is opened.

Very good idea, I've never been an applescipt guy, but that's the kind of thing that can help a lot.

Also, and more importantly, if you haven't already, post over at macfixit.com. That's where you should be asking these kinds of questions. We're just musicians here! Good luck!

Macfixit IS a great place, but you don't know half the truth upon our users, we have even people from A…e here, developers, famous engineers to artists… a real mess
And there's a lot of accumulated experiences, if we don't find, most of the tims it's desperate.

Now… I think of something, there' on bootup a switch between video drivers, the one to boot, then the real one in the system… maybe there's something there. Have you checked the video drivers are right? Just wondering.
