| Power Mac G4 Help Me Identify A Replacement Component! |
Posted by: jajan547 on 2022-03-08 08:19:39
Hello everyone I appreciate any help anyone can provide. This component was lost on this board I am fixing for a friend and I have no clue what replacement to order or where to get it or what size and value I need. Thanks again! |

It looks like you fixed the crystal and the smashed component is probably just a bypass cap so its value would not be critical. The chip is probably ok, unless that one pin on the end is broken? I've repaired broken pins by grinding away the plastic enough to expose the internal copper enough to solder to.
What is this from, a MDD? |

This is the motherboard of a 1.25GHz power Mac G4 so I can just bridge it or do I leave it? |

Appears to be a small capacitor. Sometimes a computer could live without one, but the traces seem to be going to a chip which may have importance. I probably wouldn't bridge that, unless you're overclocking and you need to connect 2 PLL pads together, LOL. |

Any idea what value the component may be? I can look, but I need to find the schematic for your specific board. What's the part number of your motherboard? Usually starts with an 820. |

I have to look when I get home in about an hour and a half I know it’s the 1.25ghz mud model |

Well, that's easy to figure out. Just a moment...
EDIT: There does not appear to be a schematic for your board. Try checking the other 2 caps' values with a multimeter.
mud model Accurate. |

Accurate. Lol I will when I get home. |

It would likely short the power rails if it's a bypass cap. In general capacitors are DC blockers, so approximate an open circuit at DC rather than a short, so bridging where one was is almost always a bad plan |

I unbridged the connections before powering it on (because I did bridge them while it was unplugged) |
