Re: Replacement refurb board blew caps instantly.

Thanks for the information, Toasty.

Thanks, Bonez. I was thinking it was the dates and the brand more than the series. Thanks for the clarification.

Here's a pic of my original motherboard with a bank of blown Nichi's as well as the inside of the PSU (there's a Ruby just below the heat sink lower right and one at the very back by the vent):...

Thanks Per Hansson. I've been perusing the tut's and other posts on Badcaps for the last couple of weeks. I'll probably end up going the recap route rather than hoping I find a refurb that has had the caps replaced. Thanks also for the recommendation of TopCat's services.

Toasty: Thanks, the Nichicons that I can see are H0251 H0248, so yes, they are on the dud hit list.

There are a couple of LTecs and a couple of Rubycons in there as well.

Per Hansson: Yes, I've already returned the refurb. This thread is more for when I either recap my original board, or get another refurb, so I don't keep blowing caps.

Toasty: I did end up getting the case open on the PSU. It slid off with some force...more like a quick rap of my fist. Although there are a few larger Nichicons in there, they appear to be in good working order.

Re: Replacement refurb board blew caps instantly.

Thanks for the replies.

The date codes on the refurb were identical to that as my original. The polarity has not been reversed.

Toasty: I'm not really sure how I would go about re-forming the caps. Is that via software or hardware?

This link: [url]http://images04.olx.in/ui/2/63/29/34675429_1.jpg[/url] is the power supply that is on the 650, and I can get the plastic shroud off the front, but the sides don't want to budge. I don't want to cavemen them off.

Thanks again,...

Hi all,

I have a Dell motherboard that has the capacitor plague and 12 caps have obvious signs of failure. The majority of failed caps are the infamous Nichicon variety with a date code: HN0249 (1800uF, 6.3v). Initial symptoms were a couple of thermal event errors followed by the system not booting at all.

I bought a refurbished board (supposedly refurbed by Dell) and noticed that it had the exact same caps as the old board, but since it had a warranty, I thought I'd install it and see what happened. Well, two caps blew immediately on the first boot attempt.
