The "20%" markings confirm it isn't a battery. Axial electrolytic capacitor. Radial electrolytic capacitor. Scott |

Whew! OK, I start removing the board in a few hours...wish me luck! |

OK, didn't get very far. I'm not sure how to remove the ribbon cable that is connecting the two boards. Do I just pull on it? |

Thanks Scott, well, I cut the old one out and crimped the new one in. I know that's not the right way.... I'm getting 4.60 on the multimeter now. Still not saving stats though. I think I need to clear out all of the stats, I'm trying to get to the service menu (I had trouble the first time, took like 10 attempts). I'm 50 attempts in and I can't get in. When I was in the first time I set it up fo free play. The routine you need to do to get in to the menu is: While in attract mode, 1- Hold down player one button. 2 - Press and release the service button. 3 - Release player one button. But now as soon as I touch the one player button it exits attrct mode (I'm guessing because it's in free play mode :dunno).... Is there a work around this situation? Is there any other way of getting into the service menu? Also, is the service button supposed to add credits? Thanks. |
