Title: Uh Oh, What did I do?
Post by: Neverending Project on September 22, 2007, 02:25:41 am
I have a Monivision 29" VGA monitor that worked fine before I started mucking with it. I de-cased it, discharged it, and then mounted it (rotated) in my cabinet. I know it got bumped around a bit because it was heavy, and it was a (very) tight fit. So now this is the picture I get.

Any ideas?

Why did you discharge it?  Did you remove the chassis when you decased it?

I discharged it because I was really paranoid about hurting myself when I moved it.

I did not disconnect the chassis, but some of the boards were only hanging on by their wire harnesses, because they were mounted to the monitor case. When I pulled the monitor from the case, they weren't mounted to anything.

looks like either a plug off,broken connector or trace or a bad solder joint somewhere-to me it actually looks like the video plug has been disturbed

Looks like the same picture that you get when you turn up "screen" to high on the HVT. Check that first...

That was exactly it! Just a quarter turn of the screen knob went from the previous picture to this one (atttached). Thank you so much!  :applaud:

Now on to the next problems to overcome...

How does Joust 2 look on there? It would suit your layout better, since its vertical.

Yeah, I plan on using my old mac (or maybe a newish Mac Mini) as the heart. The problem is that there are no mac drivers for all the good stuff out there - Ultrastick, ArcadeVGA, LED-Wiz, Light-guns, front ends. That just means more work intially, but having a Mac in my arcade machine... priceless.

Is that mac mame?  If so, what version?  Thanks!
Actually, MacMame is no longer in development and it was left at a PPC version. This is MAME OSX (http://mameosx.sourceforge.net/ (http://mameosx.sourceforge.net/)), which is Universal Binary, stays current with the latest MAME version, and takes advantage of Core Image and Core Audio.

In my haste (and excitement) to see if the monitor still worked, I just plugged in my laptop using "video-mirroring", so I could not run it full-screen. When I get a bit more time I will check out some vertical games and post pics if you want. It is my plan to run everything full-screen when it is complete.

I'm glad to see there is Mac interest out there. I think it is only more difficult for us because the majority of developers are Windows based. I'm a mac guy through-and-through, so I want my arcade machine to be a mac-guy too.  Maybe I'll start some mac-specific posts if there is anyone out ther ewho wants to collaborate on bring some mac to the arcade community.
Title: Monitor Image Fades Away
Post by: Neverending Project on September 28, 2007, 01:51:56 am
Many thanks to the help (especially Level42) in determining that it was the "screen" control to return my monitor to a working state. But now a new phenomenon is occurring. When there is a lot of white on the screen, the monitor fades out to the washed out image I posted previously. If there is mostly black or dark on the monitor, it does not happen. Powering off the monitor or an ever-so-slight turn of the screen knob will correct the screen.

Nothing is moving or changing while the "fade" happens, and it seems to only take a few minutes before the screen is entirely washed out. It is like something is "leaking" when there is a bright image on the screen, but fine when it is dark.

Any ideas?
