  • You could have got those caps at Radio Shack.

  • @tickyul

    Hmm, I think I looked but didn't see them there. Or maybe they were going to cost a lot more.

  • Capacitors....WHY????

    Damn them thingies!!!

  • @tickyul

    :-)

  • what about the volt if it's high or low like i have 20 pcs electrolytic capacitor 330uf 200v but i find 20 pcs electrolytic capacitor 330uf 25v

  • @Sajjadkhan456456

    Did you intend to put 20V in place of 200V?

    I believe the higher rating is fine... meaning putting in a higher rated one is okay. I'm basing that off of what I recall from what I posted as other sources for the information I used.

    If you are not sure... then I suggest you look into it a little more... but my free opinion is that I seem to recall it being fine. I am pretty sure I used higher rated ones myself.

  • I have an "ICY BOX IB-NAS4220-B" with the same problem. When I take a look at the sticker on the power supply I saw that this is the same as the LaCie One.

    I also have a LaCie 3.5" 160GB external drive that crash.... For me, nô more LaCie.

    Thanks

  • @FredZed11

    Wow... pretty bad.

  • I'll never EVER buy a lacie again - worked on too many projects where they've died on me.

  • I have many customers who had the same problem. I have two units that I have to repair. What a joke. Why no class action against these clowns?

  • Had a similar type PSU for an ICYBOX NAS unit (IB 4220 B) but it was the NAS making the hissing. Followed your tutorial and after spending a couple of pounds on new capacitors, the PSU is good as new and all hissing has stopped. The manufacturers had already been using 16v capacitors in the PSU , but these were still bulging, so replaced as shown . Well pleased ! Cheers!

  • @wwhite139

    Very good to hear! Good work! :-)

  • Thanks, I replaced 4 capacitors and now its working fine. Internet is great!

  • @Lommeland

    Awesome!  Glad to hear it.

  • Might I ask if there is an advantage to using the 16volt rather than the 10volt capacitor? If I am working on an atx psu do you think that it will up the power/efficiency of the unit?

  • @The561Hero

    I must admit I am pretty much a novice when it comes to electronic theory.

    Guessing here, but no I would not think that upping the rating of the capacitors is going to have any resulting increase in power/efficiency of the unit.

    I am thinking the only thing it will do is cause the capacitors to not go out as easily.

  • Hey, thanks for the vid. I was starting to have problems with one of my drives and noticed the hissing adapter, so after Googling for info, I decided to just order a new adapter, it should arrive tomorrow, I hope that will solve my issue.

    However, I was wondering, what could happen if I'd let the adapter on too long? That is, plugged in the socket, but with the drive off. Do you think there's any risk of fire or would the thing just stop functioning with a pop? Thanks.

  • @nemoDaedalus

    Welcome... The new adapter is probably the safest option.

    I do not think I am qualified to really say what would happen. Ideally the capacitors should just blow/fail and the current would not flow out to the drive (powered on or not). However, when dealing with electricity I guess anything is possible and if you have critical data on that drive you are risking that data having the potentially fualty power supply connected to it. Again though... I really do not know.

  • @0MrENigma0 Ok, thanks for your reply, much appreciated :)

  • Hi, firstly, thanks for the great tutorial. I tried this repair that you described, and everything went pretty smoothly, from ordering the new caps from china to soldering. i got the same spec caps as you decribed. but when i went to plug-in the power supply, i heard two loud pops and a burning smell. i quickly disconnected it and found two of my newly installed caps had blown-up inside. i was careful to observe the polarity as described. any idea what went wrong? Thank you.

  • @elbertchu

    Are those the only parts that blew? You said two of them... were there others you changed that were okay?

    Did you replace the same three that I did, or did you replace the other two?

  • @0MrENigma0 i replaced four in total, and i think they are in different positions than the ones you changed. the two that blew have the board marked: c19 & c20. on my board there are a cluster of 4 together, and then a fifth one. i left the fifth one alone since the top was not bulging.

  • @elbertchu

    Are you sure they were all the same rating? The two that remained on my board were actually higher rated capacitors than the ones I replaced. Is it possible that two of the ones you replaces were originally rated higher than the ones you replaced them with?

    Sorry your board was not the same. :-(

  • @0MrENigma0 well two of them were 16v and two were 10v, both 1000uf. on closer inspection now, i notice that the old ones are taller than the new ones by less than .25in but they are 1000uf 16V — but that shouldn't make a difference if the rating is the same right?

  • @elbertchu

    No, as far as I know, the height should not matter... just the specs. If the new ones were rated the same or better for the V, and they were placed in the correct polarity, then it is pretty odd that they blew. Possibly there is something else wrong on the board... unfortunately if there is it is beyond my abilities. :-(

  • ... i was wondering, what damages the adapter? i mean, is it a design problem and i would have to change the capacitors every once in a while? does using a current regulator make it less possible?

  • @oscarh13

    I think mainly it is just a sub standard batch of capacitors supplied for building the power supply. It could be a design issue, but I really do not know. I would like to say one is already built into the power supply, but could not say. Could even be that the capacitors used just really couldn't handle the current. I would guess that if you replace with a bit higher rated capacitor than the ones that go bad then you should be fine long term.

  • Very helpful, thank you. Though, I wasn't able to get the darn thing open...any suggestions for that? Screw drivers aren't working

  • @Annarianexile

    You have to wedge it in and twist to pry it then slide along the edge a little more and do the same and just keep working at it.  It is not easy... then finally when I had about half of it loose I ended up putting gloves (leather) on and forced the remaining part because it was glued. Probably the most difficult part of the whole thing.

  • WOOT external tutorials!
