Hi everyone, im a new member here and need some help. I just got a Sega Blast City that uses a Nanao MS-2931 monitor. This monitor uses a 3 button control for the on screen display adjustment, but the mode button does nothing, even if I hold it down. The only button that does anything is the up button. If I hold that down for about 4 seconds, the words MODE and EXTENTION come up on the screen, but that's it, nothing else happens.
Is there something I'm missing? I want to get a good screen adjustment before I pull the machine apart to clean it out and maybe try to adjust the convergence. Thank you if someone can help me with this.
