Title: Monitor won't quite stop rolling and just 'stick'
Post by: newkillergenius on January 26, 2010, 09:46:34 am
Hey team-

I've been mucking with this for a bit but can't quite figure this out!

I picked up a Track & Field.  It needed a monitor.  I got a good  known working monitor and put it in.
Turned it on.  Great picture!  Nice & vibrant!  Oh, it's slightly rolling.  No problem, I'll just adjust the vertical hold and we're off!

OK- did that fix it?  No!
OK- how about now?  No!

Jeeeeesus.  OK- to make a very very long story short- the image just simply will not stop rolling and just 'lock in'.  Everything is perfect but it just wont stop.  And we have adjusted it to the point where it will just creeeeeeeeeeeep along- but it wont ever just stay locked, the damn thing!  :lol

Anyone have any suggestion as to how I can stop this?  :banghead:  Thanks for your help-

Justin

Make and model of monitor installed in this cabinet is.....?

Is sync connected properly?

Has monitor in question been recapped recently?

Hi Ken - thanks for your post man!

I'm not sure of the model on the monitor, I will have a look tonight when I go back over.  The monitor has not been recently capped.  It was working 100% when it was pulled from a Neo-Geo setup earlier in the day.  As far as the sync, there are 3 pins at the sync area, and it only displays a picture with 1 setting.  It just wont stop rolling.  So I guess I can't actually say the sync is connected properly, though any other configuration makes it go haywire.  This one configuration I have it in now settles the image, it just wont lock.

Try a loop over from the Horizontal pin to the Vertical sync pin.

How do I tell which is which- cause there are 3 pins-  the current config has black wire at far right and white wire at far left, with a vacancy in the center pin.  I feel retarded. :lol  Don't normally have this many issues....

And I am trying to understand this extra black wire.  Seems like there would just be H sync for this board right?  Why the 2 wires?  Ground is at the RGB pinout.

So you have two ground wires then ?

R G B Ground . .        Ground . Sync  (?)

Still best to know which monitor you have though.  ;)

It appears to be the case....the thing is, this must have worked for some sort of monitor at some point-it almost does for this one.  But still no lock. (http://forum.arcadecontrols.com/Smileys/default/blowup.gif)

pic as promised- found the problem.  After the board there is 1 molex quickconnect and someone had changed the wire color there from white to black, and from black to white.  So, this whole time black was sync, not white.  Problem solved.
