Hi everyone! I just picked up a Pachislo Gamera High Grade Vision machine for $15 dollars at a yard sale. It works- the reels spin, lights and buttons flash, and I collect my winnings, however, there is no sound or video. When I turn the machine on there is sort of a popping sound, and then the screen starts out white, and turns to red and stays that way for a while. Then it makes a popping sound again, goes back to white and then switches to red. The sound is also non-existent, all that is heard is the sound of the reels spinning. I know very little about these machines, and I have tried cleaning the board that looks like is connected to the screen and speakers. If anyone knows how this could be fixed or has any form of schematics, that would be greatly appreciated. I have already tried a system reset. Thanks!
