Someone on one of these groups suggested a very good service manual site,
but I never find it because the link to open the document is obscure. The PSU is the worst I've seen that didn't already go bang! Changed all the bulged electrolytics and ESR tested all the others - but I think I got one mixed up putting it back. The service manual would be quite handy. Or I could just fire it up and see how loud the bang is.................... Thanks for any help. |

Putting some components back in the wrong place in a SMPSU doesn't usually leave time to switch on a IR thermometer. |

That isn't going to tell me which capacitors I put in the wrong holes. |

That isn't going to tell me which capacitors I put in the wrong holes. The guys in the badcaps.net Power Supply Design and Troubleshooting forum might surprise you. They're the most passionate group of PSU enthusiasts on the Inet AFAIK. They love to reverse engineer undocumented PSUs. They may even have the service manual that you seek or a pertinent schematic. The only downside is that you need to sign up to access the forum. Thank you, -- Don Kuenz, KB7RPU |
