    Blast City 15K dim

    I was adjusting the monitor dip switches on my Blast City to switch between 15k / 24k / 31k and now the 15k is about half as bright as normal.

    I had a Dreamcast connected to VGA and understand having VGA plugged in while on 15k can cause a dim picture. I unplugged the VGA cable and the picture got slightly brighter, but still practically unplayable.

    The 31k over VGA is normal brightness.

    I've tested CPS2, Namco System 10, and Pandora Box 4 using 15k and all are dim.

    Any suggestions?

    mine always were as well, you can try a cap kit? I assume you adjusted all the pots like brightness, contrast, RBG, etc to try and get it brighter?

    I just found the issue. The DSUB switch wasn’t fully in the off position. I turned it back on and off and brightness looks good now. Those dip switches are in a horrible spot. I’ve seen some people move the remote board out and under the control panel. I might have to do that.

    15k and 31k should have their own service menu settings which appear based on the input signal.

    Glad you found the real problem.
