Check across all the ceramic capacitors with a multimeter for shorts/low impedance. And then check the MOSFETS. |

Lots of tantalums to check on the top side of that board! |

Also, depending on the configuration of that board and/or BIOS settings it might not display anything on the external VGA connector. If you haven't already tried it might be worth removing the scope board off the motherboard to test it. |

some of the mosfets are not even accessible with standard test leads. (maybe with miniature test hooks) As mentionned, I measured a suspicious 8 Ohms across an electrolytic cap (even with the cap removed) The problem is that I have no idea of what supply voltage it should be. No idea either of what components are supplied by this rail. Maybe tens of them. Which one of them measures 8 ohms? No idea. :-// |
