SheevaPlug power supply blown up

[NewIT_Jason]

The Official line from Globalscale is any unit manufactured after 27/04/10 has the new PSU.  From our side we consider any unit we sold after July 2010 should have the new PSU.
But to answer your question, no there is no way of telling from looking at the outside of the unit, what it has in there.

Just my +1.

I bought mine in January 2010, and it just died a couple of hours ago after continuously running since then, without problems. It was in the same exact spot for all this time, in my living room which tends to get hot in the summer (~27C), there was nothing connected to USB (except an external laptop hdd for 2 weeks) AND it was on an UPS for the last couple of months.
Green LED and NIC LEDs are both blinking when I plug the power cable in and that's it. As am using it for my home router, I was lucky to find this and the other thread about running it on USB. The PSU is not completely dead after all, I was able to kickstart the plug and run it from USB.

I emailed Jason and I'm looking forward to resolving this issue ASAP. I don't really want to power it using my desktop computer as a power supply .

I remember a really fast and smooth delivery when I bought it last year, I've got it in like 3 days after ordering it through the shop. Hoping for a fast resolution now, too

It turns out my SheevaPlug (bought in January 2010) is out of warranty and a replacement PSU would cost me £12.5 + £9.5 shipping, so I turned to one of my collegues who knows this stuff and he replaced the blown capacitor (luckily it didn't actually blow up, there was no visible damage or "goo" inside the PSU as shown on those pictures some of you posted) and now the Plug is working just fine. We'll see for how long

I thought I had avoided the notorious PSU problems until mine gave out 2 days ago.
I opened the plug up (Bought Feb 2010) and found a 1000uF 6.3V 105C Electrolytic Capacitor had bulged. Replaced it with a 1000 uF 16V 105C from Maplin and now works again.

I bought my sheevaplug in september 2010 and it seems the PSU died yesterday. The symptoms are the same, green LED and network LEDs light up when plugged in but the second LED doesn't and nothing else happens, the network interface won't be activated and the serial USB interface also doesn't work anymore.

Since the unit is theoretically still within warranty, I didn't want to open it and wrote to Globalscale Technologies and hope, they are going to offer a solution.

Since from my understanding my unit should have been one with the "new" PSU it seems that I was either out of luck or the new PSU is not really better than the old one.

Hi.

I've been following the discussion about the blown PSUs. As of now my sheevaplug is still running (bought june 2010). But the plug suddenly have problems detecting the external (selfpowered) harddrive, so I opened the plug and examined the big capacitor and discovered that it had a small brown stripe. So I guess I need a new PSU too, very soon - might as well order it - but since I'm out of warranty I'm thinking about using a separate PSU to keep the sheeva as cool as possible.
So should I go for
a) buy the new psu from NewIt - and possible end op in the same situation in a year or two?
b) mod my sheeva to use external PSU - I except this solution will work longer than a)

Is it a) or is it b)?

I go for b) , I'd this for the Sheeva and the GuruPlug.

But:
The point is the "hot spot" inside of the capacitor!
So the original PSU can blow-up in time again, because of the 'small-capacitor' size.

Therefore @trampjuice mention it in #reply 63, the size does it all.
The point is that the 6.3V capacitor is heaten up much more (on the inside) then the 16V type (has a better cooling, because of the size).

So the live of a 6.3V cap. is limited

Thanks for the reply.

I'll go for b) then - do any of you in here know how sensitive the sheeva is to the voltage? Could I use an external 6 volt psu for example?

Hi I'm a new entry in psu burned club This is my Sheevaplug details 1374 2010-04-19 15:57:14   Order Completed   RJ574192995GB   £121.00
and you can see psu pic below. I've already ordered 2 psu on shop (1 as spare).

The symptoms are the same, green LED and network LEDs light up when plugged in but the second LED doesn't and nothing else happens, the network interface won't be activated and the serial USB interface also doesn't work anymore.

I'm experiencing the exact same thing since this morning. I bought it somewhere around March 2010 so that's 2 years of running it 24/7, with hot summers (30+) but w/o powering any USB devices from it.

Anyway, I came here to ask if the LEDs lighting up means the PSU is OK but I got my answer.

Well done NewIt. New PSU ordered last Saturday eve, delivered to Ireland Wed. Installed and my lovely Sheeva is now happily running Logitech Media Server (the artist formerly known as SqueezeboxServer) again.

Thanks for the prompt service:-)
