i have a question for everyone... has anyone dealt with these monitors? mine luckly will come on but when i try to hook it up to pacman it wont sync right, the screen is greenish and lines look like a osciliscope at times depending how you tune the pots, i cant seem to find a pinout of the monitor jack on the mainboard. its marked R G and B but i cant see the other stuff as it is missing, i paid 20$ for it untested and all but i can tune the color pots and get multiple colors... red, green, blue, yellow, magenta and so on... help plz???
 
Does it look like this?

thats the one.... um what would cause my syncing issue? plus the oscilliscope looking picture on the screen, uum i can plug ms.pac in and see the marquee logo on the attract screen only that its greenish and the dots and ghosts cant be made out.
 
Well, if yours is 100v and you are connecting 120v, that might be a problem. Otherwise, post a pic of your video connection....
 
ok i may have screwed up, its definatly a 100v monitor, uum i dont have a nintendo xformer to test it with as i know those are 100v stepdown transformers, how do i test it correctly? what do i buy? could any damage of been caused? btw my model is m21cxx

I told you yesterday....that's an early Happ (re-branded) Vision Pro monitor. Google is your friend...

It's a switch mode powered monitor. That means it'll operate at 90VAC to 250VAC (give or take). Good old USA 120VAC won't hurt it. It's auto syncing (like I told you yesterday). The six pin input header is....red/green/blue/ground/horizontal sync/vertical sync. It auto syncs for negative or positive sync....for composite sync, use the horizontal input...like most monitors. You've probably got the sync wired wrong....and you stilll need to do a cap kit like I told you. That will probably get rid of the pulsing.
