atomiswave monitor adjustment

[zlk]

I have an atomiswave cab with a weiya 3129d01 chasis and a samsung screen.  I have tried all adjustments to shrink the vertical size so that games like ibara display properly on my cab.  Right now I can't see the entire screen as the left and right parts are cut off.  The picture is too wide.  I found this video about adjusting the horizontal width coil : http://www.arcaderepairtips.com/2010/04/21/adjusting-the-horizontal-width-coil/

This seems like it could be helpful, but I can't find anything that looks like that on the chasis.  Any suggestions?  Does anyone know what all the pots do on the chasis?

I see there are some black plastic things sticking out of the back of the tube of the monitor.  Can these be adjusted?

You need VR7 pot on the chassis . v.size its called.

By the little black things do you mean coming off the big black block? thats the flyback if so and the 3 pots are inner/outer focus, and screen volts, none of these are going to help you really, and are usually factory set.

VR7 is already turned as far as it will go.  The screen is still too big unfortunately.

mmm, could be the screen volts or b+ adjustment but its not really something to go fiddling with, both can cause the screen to be a bit too large however.
