It all looks like new. No damage to see whatsoever. The smell must be long gone now. I did look inside when it happened two months ago, but couldn't smell anything then. So I figured it was the PSU (which is sealed, so no smell… maybe…). > Have you used a multimeter to test the PSU ? If you try this look for > instructions PDUs do not like no-load conditions. No, I don't know how to use a multimeter. But I will ask a friend of mine, an electrician, he will tell me. With PDUs you mean PSUs? No no-load contition… whould make me put all together again just to have load on it? A lot of work. I figure, if I don't hear the click when putting power on (pluggin the cable in) I'd have to investigate this matter first, right? > You cannot detect a rancid burn smell in the PSU ? Nope. > No blackened or brown parts ? None whatsoever. > A used unit from the swap list will be much cheaper than a new one or > having it rebuilt. I'm from Austria/Europe. The swap list is out of reach for me. But I do have a sister who lives in New York (the state, not the city). So there might be a way… > I don't know about converting a standard unit. you > could try a web search using the PSU swap out parameters. I'll keep this in mind. But this would definately be a major project for me. > It is doubtful you could repair it yourself. A zapped power handling diode > or condenser is possible. But again you would probably need to have a pro > solder it in. you have to find it first. I have a college who is sort of a pro, so I would ask him. I just want to be able to tell him where he should start looking. It would be nice if I was able to tell him which part he should replace. > From what you describe this machine should smell bad inside the case and / > or PSU . But the smell dissipates over time. That's what propably happened. > Such damage should be easy to see and smell. I was hoping for it. But no way to see it for me. I made some picture of the inside of the PSU, and the system board. I will try to put them online today. Maybe you or someone on the G-List will be able to see something – to me it looks all like new.
