I am trying to repair a sega super monaco gp arcade game. I have two problems. the first problem is that all the sprites have little 1 pixel white dots on the screen. the dots go across the sprites both up and down so that the dots look like they are making up a matrix of cubes. all the other graphics are perfect with no problems. In diagnostics I ran the rom ram and special ic chip test and got back good test results. My second problem is that the volume is at a fixed setting and sometimes is not to well heard. the music is ok but the sound effects and voice are low. adjusting the two volume controls by the test switch seems to have no effect.
camera does not photograph what is truly happening but if you look closely in the blue field to the left of sega you can see the dots. actaually the swim suit models looks horrible with dots but camera hides most of problems and this is my best picture that clearly shows something
