Title: First power up of my JAMMA brand new Monitor scrolling / colors off *Fixed*
Post by: mrclean on September 25, 2008, 08:37:45 pm
I was very happy to power on my 2nd non MAME arcade cabinet dedicated for the first time and even to see a picture even if it was all screwed up made me happy! I have a brand new Happ 19'' vision pro. the happ wire harness has these colors:

red, green, blue, black, white, yellow

my jamma harness molex connector which doesnt fit the happ monitor anyways only has:

red, greed, blue, black, white, *no yellow*

first powering on it was more or less just red crap that looked like this:

then after fooling around more with the wires it looked as if it was scrolling slanted at a weird angle, mainly red and tough to make out what game it was but you can see here Gun.smoke  :

It looks as though your sync isn't right.  You should try connecting the white wire of the games harness to the yellow and white wires of your monitor.

Use the remote adjustment board for the monitor.

The little board that is connected to your monitor chassis via the ribbon like cable and has several potentiometers on it that will be labeled hor pos, vert size, vert pos, etc.  If your monitor is new it might still be attached to the side of the monitor frame.
