Re: Instant diagnosis of bad video board caps?

Apologies again, for writing inaccurate/incomprehensible sentences, that should have read: "Possibly there is something in the .pdf files from that manufacturer, that's incompatible with the evince document reader, that I'm using on the netbook."

Whatever the cause, the image file was a good choice to resolve any problem, thanks.

[I]If[/I] I were to replace the 470uF Sanyo, I trust the same advice would hold, i.e., the brand makes no difference?

You're right about the reliability...

Re: Instant diagnosis of bad video board caps?

Apologies -- regarding an unreadable .pdf file. As my desktop machine is unusable at the moment (see above) I am continuing with a 7" netbook. I have accessed the Rubycon site, found a pdf spreadsheet, and am unable to read it!

Possibly there may be an incompatibility with Wincows 7? I use the evince, here.

Re: Instant diagnosis of bad video board caps?

Great, now I see what to look for, out of all the values there. I suspected that might be it when I first looked, but wasn't sure.
The earlier .pdf opened fine, but this one won't. On this end of the line, it's mostly blank with a sprinkling of mathematical symbols, throughout. Obviously, corrupted during transmission? Could you please resend that, in some way?

Re: Instant diagnosis of bad video board caps?

The original Teapo is 10mm(D) x 12mm(H).
That will be great -- I am curious about that.

Note: I think I have the height of the replacements mixed-up, between the two brands, in a prior post. The originals are all 12mm high. And, there would be clearance if the replacements had to be a bit higher....

Re: Instant diagnosis of bad video board caps?

Thanks for the pointers, as without that I would have guessed the wrong number. This is what we have on the Teapo 1000uF 6.3V:

SC105ºC -- so it's an SC.

There are three of these, and one of these:
Sanyo 470uF 16V 105ºC S.E.56
WG

I have these in my Shopping Cart on this site:
3 x 1000uF 6.3v 10mm HN Series (Nichicon)
3 x 1000uF 10v 10mm MCZ Series (Rubycon)
1 x 470uF 16v 8mm HN Series (Nichicon)
1 x 470uF 25v 8mm PX Series (Rubycon)

Re: Instant diagnosis of bad video board caps?

Thanks for asking the right question!

I will open the case again and look for -- what, a two or three character alpha-numeric code printed somewhere on the insulating sleeve, and this would be the 'series'?

So far I have only measured their dimensions and noted their maximum temperature ratings (that's 105C).

I'm used to replacing, years ago, the electrolytics in power supplies, so this level of refinement is new to me. I will check on this and post, so you can tell me what to do with this.

Two words to best describe the X300SE

It's not worth the price of a fan. [URL="http://www.tomshardware.co.uk/forum/214256-11-overclocked-x300-128mb-hypermemory#t1405822"]Read the last two words in the first sentence[/URL] of this post. That's pretty accurate.

Another review at the time of its release questioned why it existed at all, and finished by saying, it's a nice board for an "office machine".

It was slightly better than the average onboard video chip -- of seven years ago. I just want to keep it going until the motherboard...

Rubycon vs Nichicon brands

I only brought that up because I assume it would run 'warmer' than a motherboard, and so would give the 'nod' to a brand of caps that works better under these conditions.

I just took the board taken apart to modify the heat sink, and there's no visible indication of heat damage (discoloration, or anything else). In fact, the board and components all look like brand-new.

I take it, from the comments so far, that either brand of caps would be equally suitable for this application?

By the way, the selection of...

Re: Instant diagnosis of bad video board caps?

@PCBONEZ:
Thanks! Good explanation. So, as long as I match or better the original voltage, no difference between these two options.

And, I'm surmising from your comment, keeping the dielectric formed will not be a significant consideration, by going so slightly over the original voltage specs. (By 'going over' I don't mean the board will increase its voltage in response to the cap; I just mean, the new cap will exceed, or be greater than, the [i]specs[/i] of the old one).

Does one of these brands have...

Re: Instant diagnosis of bad video board caps?

OK, I'm ready to go with recapping the video board -- only four caps over 330uF. Is it correct, not worthwhile to bother with the smaller ones, without soldered leads?

This will cost less than an ESR meter!

With the Rubycons, I can go a little higher on the voltage specs, compared to the originals' values: with the 1000uF caps, I can go to 10v vs. the original 6.3v; with the 470uF cap I can go to 25v vs. the original 16v. I have heard higher is better, but I'm not sure if there could be problems, with this...

Moving right along ...

Good point, as that will let me replace the board and keep running while I still need the older OS. Probably correct, and if I were in the States, I'd already have sent $24.99 - $34.99 to Newegg, get something that handles DX11. As it is, the X300 meets my basic needs, and the recapping looks reasonable compared to what I'd spend here (at least 2x the higher end of the Newegg price range) for a replacement. Besides, sounds like fun ...
Good idea. I've already beveled the heatsink's corner, and it no longer touches the cap. To my slight disappointment,...

Why are we doing all this??

Yes, that crossed my mind, but there are other factors ... I'm dual-booting Windows 7 Professional / Windows 2000 Professional, and a new card may not have drivers for the latter.

I might add, the X300 is running with Windows 7 just fine. It includes a driver for this board, since ATI-AMD's driver support for this model goes up to Vista, only.

This I may consider, a completely new video card, once Win 7 is running and configured as well as Win 2K ... the only reason the older system is still here. So I have to run in parallel...

One more thing -- before pulling the caps

Wow! This a great forum! Thanks, mariushm, for all the practical hints, and especially for the electronics supply references. I am in Portugal and we don't have any RadioShacks here.

Looking at the photo I posted, and how the sharp edge of the heatsink is cutting into the cap's insulating sleeve (note a little curl of plastic, near the cap's base, where the cap and sink touch), I will first try one more thing: remove the heatsink from the card and put a 45° bevel on that edge. I hope it's fairly soft aluminum.

Re: Instant diagnosis of bad video board caps?

Thanks for the help!

Question: Of the brands you mentioned, on the badcaps home page, lefthand menu (Capacitor Kits) I don't see Panasonic or United ChemiCon KZE -- or RX. How, or where, does one order these (should one of these brands be the preferred choice, over Rubicon and Nichicon)?

You raise a good point about deterioration that wouldn't be noticed with a regular Capacitance Meter. Yes, I may as well replace all -- they're only four larger electrolytics, in total, on the Radeon board.

Another...

Re: Instant diagnosis of bad video board caps?

The case was opened and no signs of oozing or bulging caps on the motherboard.

The video card was removed for close examination. This is an ATI Radeon X300SE 256MB with HyperMemory, and the electrolytics here also show no signs of oozing bulging. I have a Capacitance Meter on the way through the mail, but after I saw C105, and how it was installed, I may not even need that (see attached image).

This card has a fanless heatsink, that therefore runs warmer than fan-cooled models, but note the Radeon board's...

Re: New Members - please post your introductions here

Ron here. I just started having a problem with some instability on my desktop, and after blaming it on the new OS (Windows 7) I just realized it happens also with the old one (Windows 2000). So, from there, I went to reading the 'Capacitor Plague' article, to this site.

My welcome message asked me to complete my Profile, but when I went there, I got only this:

Instant diagnosis of bad video board caps?

Hi, new member here! Just found out about the 'capacitor plague' and what a surprise, there is such a store of information available about it.

does the following make for an instant diagnosis of bad caps on the video board?

About once every day or two, my monitor instantly goes black, sometimes with the display driver restarting, but more often with a MS Windows blue-screen listing (among other things) the name of the display driver.

At this point, it could be a number of things, but I noticed something unusual, when I happened to...
