Hey guys. I'm trying to hookup a computer to my Vs. cabinet to run a "Multi-Vs." setup. The actual Vs. SMB hardware works fine. When I hookup the computer to the Sanyo, it looks like this...

...the Black and White appear to be reversed. It's not the computer or the VGA cable. It's gotta be something with the monitor. I hooked up a different monitor and the colors are fine, so it's something with the Sanyo.

Any ideas? Thanks.
 
if you are gonna run any other game/computer on a sanyo then you will need an inverter.

or you could toss a K7000 in there and be fine.

keep the sanyo for another nintendo cab.

try playing mario inverted it's wacky looking.

Makes sense. Here's what it looks like on my 13" k7000 test bench monitor...

So there's no way to change the Sanyo to accept regular video or anything else I can do? What type of inverter would I need. I have a 2 extra K7000s but they are for 25" tubes. I can use them on this 19" Sanyo tube?

Another reason I wanted to use the Sanyo is because it has the onboard sound amp and I wouldn't have to hack some computer speakers for sound. Everything is working great right now except for the inverted colors.

this is what you need to invert the colors.

no you cannot run a 25" chassis on a 19" tube it will do horrible things.

use the inverter in line with the video and it will do what you need.
you will also need to power the inverter.

in the attached photo this is where on the sanyo chassis to get power from to power the inverter.

i have them if you need one. but see if you have one on the flyback cage and is not hooked up.

Thanks buffett! Is there a specific place i can get one, or just post in the Wanted section?
 
I'm sure you can do something because Atari used (about) the same Sanyo chassis and it was simply missing some components to not have the inverted inputs... However that means modding the monitor at component level.

I think I've seen pretty simple circuits to invert the signal, but wouldn't it be possible to do it through software on the PC ?

yes you can do that.

but i don't recommend it there is more of a risk in messing something up on the chassis

but i find that the inverter board is less invasive and you can choose weather to use it or not.

Thanks to the great Arcade Buffett, I received the inverter board and here's how it turned out...

It turns out the inverter requires 12vdc and a ground to operate. I simply ran some wires from one of the computer's extra power supply connectors, adjusted the RGB, etc, and it looks amazing.

Again, many thanks to The Arcade Buffett for saving the day for me as I would have had to install a different monitor to complete this project. I will post a video later of this "Multi-Vs./Nintendo cabinet project. Stay tuned.

One thing though, I can't seem to find the pot for adjusting the horizontal position. It's a Sharp XM monitor which I was told was a clone of the Sanyo. Anyone know?

looking Sweet!!!!!

glad the inverter worked the way you needed it to.

there should be a pot on the chassis for adjusting the H-Position.
where it is located on the chassis, i am not sure on that model.
