typically you don't set a monitor for refresh rate. Normally it'll either accept the signal or it won't. a lot of newer monitors just don't accept anything below the 31KHz. Someone please correct me if I'm wrong (seriously, that isn't sarcastic).
It "can" autodetect, this depends on the chassis in usage, if it dosent you should be able to set the freqency manually on the CP of the Chassis. Otherwise it' a chassis designed for only 31khz BUT compatible with the Tube, because the Tube can manage trisync. Plz try to post a Pic of the CP.
Check the remote board for the monitor under the CP. I have a Blast as well. If you do not have the digital chassis (with On Screen Display), there will be a small dipswitch under the CP, on the remote board for the monitor (on which you set contrast, H-sync, etc). It is on the right of the small PCB, and there should be a sticker in the bottom half of the CP telling you how to set the dipswitch for 15k.
The Blast city cabs all have a tri-sync chassis (MS2930 or MS2931)
Ah, the monitor (or at least the chassis) is not original anymore, as you can see from the mismatch in the schematic versus the remote board.
Most probably a 31khz-only screen, meaning you cannot switch to 15khz. Someone here might recognize the specific Sanwa chassis and have more info. I don't

i acquired a blast city yesterday with the same chasis.
it will show video that comes in over a jamma harness from the original taito X2, but it will not show video that is coming in directly via the VGA port.
