Quadra 700 screen washed out

[ckurowic]

Hey everyone. I finally got ahold of a 68k Mac. The web page is at http://emichtm.dyndns.org

More to come soon!

However, the screen picture is washed out. It is mostly white. I have a dell flatscreen monitor attached to it that is not the issue. I tried the built in video only to get the sad Mac on startup. The other option is the Rasterops card, but this is washed out like I said. I can tell whats going on on the screen, but its rather annoying. Any tricks to fix this? (it doesn't matter what color sync profile I use, and there is no option to calibrate).

Sytem: Quadra 700

Mac OS 8.0

I don't know what controls you have on that monitor, but a washed-out image is generally the result of excessive brightness/insufficient contrast. Try adjusting those (if possible) and see if you can make things look more to your liking.

What's the code under the Sad Mac?

The contrast and brightness are the things I tried without success. I thought this was the problem at first.

The code under the sad mac is unreadable because the image is "scattered" all over the screen. there are a few places that you can tell its the sad mac face, though it has shown up normally once or twice. I'll attempt to get the code.

Bad vram can have this effect. I don't happen to have one, but I would assume that the Q700 has vram on the logic board and slots for additional vram. You might try cleaning/ removing the additional vram chips if it has any, and see if there is an improvement. I have certainly seen this work on other models: e.g., an LCIII just yesterday.

Could you upload a photo? I'm interested to see that...

Sorry I have not updated in awhile. I have been very busy with school. I'll get an image up as soon as I can.

Okay, it was the rasterops video card that was to blame. I took it out and used the built in video, now it looks just fine.
