This monitor is out of a Arachnid Galaxy dartboard.  I have had this problem in the past and sent it out and had it fixed.  It was just some bad caps and it cost me a bunch.  The monitor screen just goes black.  I have two more that are doing the same thing so I figure it must be common.  Does anyone know how to fix this problem?(which caps to change)  Does anyone know of a good place to send monitors for repair that don't rape you?
