Re: Identifying the problem with my Dell 2209WA
But if that's indeed a defective panel, which may be the case, why isn't the same defect present on the LCD conditioning screen (which basically displays various solid colors repeatedly to resolve image retention)? Could you post the links to those threads on the Dell website? I'd like to have a look at them myself.
BTW, the monitor is about 7 years old and naturally out of warranty, but I doubt Dell would offer anything but a replacement with a crappier model even if it wasn't.

Identifying the problem with my Dell 2209WA
Hi everyone,
I've been trying to identify the problem with my Dell 2209WA, which is pretty much identical to the problem described in [URL="https://www.techpowerup.com/forums/threads/display-problem-with-my-monitor-what-is-this.167663/"]this thread[/URL] for a Dell U2711. I also have a visible "smear" on the same (right) side of the display, just like the one in these images and the video posted for the U2711.

I doubt that it's an issue with the panel itself,... -
Re: Question about Series on master list
All of those are low impedance and can be used on a PC motherboard. There are differences in their ESR and ripple values. HZ is the best (HM<HN<HZ) and probably the most expensive.
As an example, for a 1000uF 6.3v 8x15mm cap:
ESR values (lower is better):
HM: 28 mOhm
HN: 20 mOhm
HZ: 14 mOhm
Ripple values (higher is better):
HM: 1490 mA
HN: 1700 mA
HZ: 2210 mA
These are their datasheets:...Leave a comment:

Re: TAGAN TG530-U15 fuse blow possible pfc cause
I have two of those one 530W (stopped using it due to some kind of coil whine) same as yours and a 480W which I bought as a backup PSU. I'm going to replace a few leaked caps in both of these with Panasonic FRs as soon as I bought a goddamn iron.
I don't know if this would help you but your burnt resistor near the heat sink reads as green-grey-brown-gold (580 ohm?) in my 480W.
As for whether or not these are worth repairing, well, these were probably one of the earliest modular PSUs and their feature list...Last edited by Nikochan; 10-15-2013, 12:08 PM.Leave a comment:

Re: MSI P45 Neo (MS-7519) complete (almost) poly recapping
Hakko has become kind of a no-no for me. I was thinking of buying an FX-888 from the sole so called "official" distributor in the country. I went there to check what they had for sale. They had four boxes of FX-888 and all of them had various missing parts. Two of them didn't even have a metal cover on their heating element inside the iron and their tips were lying around inside their nylon bags. Their boxes were nothing like I've seen on the Net either. In fact, they suspiciously looked like the Chinese ones sold...Leave a comment:

Re: MSI P45 Neo (MS-7519) complete (almost) poly recapping
Good job! What kind of soldering equipment did you use? I also have an MSI motherboard waiting to be recapped. I bought the caps but I still don't know whether or not the equipment I have is adequate for the job.

Re: Identification Problem?
If you search for the SMD code "G9" in [URL="http://ecadata.de/suchneu/such.php"]here[/URL] instead of WG9J, you'll get 9 different products but only one of them has 3 pins, which is of type [B]BF 767[/B], manufacturer is either Siemens or Philips.
Then if you go and search for BF767 in [URL="http://www.datasheetarchive.com/BF767-datasheet.html#"]this page[/URL], you will indeed find Siemens and Philips datasheets for BF767.
This Philips one for example, which is a [I]PNP Silicon Planar Transistor[/I]...Leave a comment:

Re: Coolermaster Extreme Power Plus 550W design problem
Would this help to figure it out? Schematics are towards the end of the document. You can search for [B]RP-550-PCAA-E2[/B] in the PDF which is the product number of the PSU.
There is a section around the coil on PCB that marked as L13 and according to the above document, the coil could be either one of these:
CH270060 (page 146)
CS270060 (page 149)
T106-52 (page 152)
The one I have resembles the T106-52 though.

Re: Coolermaster Extreme Power Plus 550W design problem
I don't think I have a dead PSU that features Active PFC on it. Would Farnell or Digikey have anything to replace that?Leave a comment:

This is a rather crappy picture of the PSU. The burnt coil marked with the red arrow.

Re: How bad are my soldering tools?
I've been thinking of buying a temperature controlled soldering iron/station for amateur repair works, preferably ESD safe. I have two options in the price range I'm willing to pay:
1. Hakko FX888 at around €125 (the analog one, 888D costs an additional 40 euros for some reason)
2. Ersa PTC 70 0710CD €80 ([url]http://ersa.com/art-0710cd-358-5046.html[/url])
I was hoping to get a Weller WES51 at around the same price as Hakko, but it's nowhere to be found and don't know why but the WS51 is unusually expensive...Leave a comment:

Re: Coolermaster Extreme Power Plus 550W design problem
My sis had one of these, [URL="http://intranet.coolermaster.nl/mktfiles/1188381215Product%20Sheet%20(RP-550_650-PCAA-E).pdf"]Cooler Master eXtreme Power Plus 550W (RP-550-PCAA-E2)[/URL] to be more specific. She told me that it smelt bad and got very hot, so I replaced it with a Seasonic.
When I opened it up, aside from lots of cheapo Capxon caps, I saw this coil, glued between two heat sinks which was almost charred. It probably was the source of the smell. Other than that the PSU looked okay.

Re: Need help finding replacements for KZG series caps
Yesterday I received the Nichicon caps I had ordered from Topcat's shop. Took 10 days to arrive. Just FYI.Leave a comment:

Re: Need help finding replacements for KZG series caps
Many thanks for your replies.
@mariushm
I don't think I have any another choice other than ordering online internationally and honestly, it's not the additional shipping costs that I'm worried about. Ordering from Topcat's shop costs only an additional $10, which isn't a big amount really and I bet ordering from Farnell or RS or even ebay would cost almost the same. Although I'm worried about whether or not I'll be able to receive the shipment, especially considering I may have to wait a few weeks for...Last edited by Nikochan; 09-19-2013, 10:17 AM.Leave a comment:

Need help finding replacements for KZG series caps
Hi. I have a desktop PC with an MSI 945G Platinum motherboard. I play my favorite old games on it. Sadly, one of the KZG series caps on the motherboard exploded yesterday and there are signs of leakage on top of a few others as well, so I'm thinking of replacing them.
The KZG series caps on the motherboard are as follows:
[COLOR="Red"]2 x 1000uF 6.3v M(105C) 5(7) 5C 10x12.5mm (one of these exploded yesterday)
6 x 1800uF 16v M(105C) 4(2) ND 10x25mm[/COLOR]
(There are also 8 KZE series caps (1000uF 6.3v 8x15mm) on the mobo but they look... -
