Another poorly done recap job

[c_hegge]

This time, it's a GX270. It's not as bad as some of the others I've seen on this forum, but there's plenty of room for improvement. This PC is from a business client of ours, who needs it to drive some older equipment...


The board. Note the mis-matched caps all over the VRM low. The originals were Ruby MCZ (one of which is still leaking), but guess what the guy who recapped it used as replacements...


Yup. KZG.




And it's no better elsewhere. not only do we have cheap generic Chinese caps, but GP caps at that.


I've seen worse soldering than that, but at least clean your flux of, guys...

I'm thinking I might give this one a partial polymod. These PCs often cook Rubycon caps, so I think it's about the only way I won't have to re-do it eventually.

Re: Another poorly done recap job

I've seen MUCH MUCH worse!! that one isnt too bad...

[c_hegge]

Re: Another poorly done recap job

Yeah, the soldering isn't too bad. It was more the fact that they used such low quality replacements (and possibly even left two caps bulging). It looks a lot better now that I've polymodded it.

Re: Another poorly done recap job

you know what I find amusingly ironic though, I STILL see a lot of GX270's and I still sell a lot of kits for them. These are systems that should be dead and gone by now.....but they're just stallions in the workhorse world...

That's pretty much what I've found. They seem to last darn near forever, as long as they don't cook the caps.

EDIT: I just realised in that 3rd last photo that I missed an 820uF nichicon HM. It wasn't bulged but was from the defective era (2003 dated). The replacement was a Ruby MBZ.

Re: Another poorly done recap job

nice, yeah at the school i usually just desolder caps from other dead 270s so at least they match, i have never once seen a 270 have bloated cpu caps if they are panasonic, on some the big 1500uf near the agp slot pannys seem to actually raise off the board instead of venting.

My personal 270 is a SSF with the following. 2GB ram, 3.4Ghz Pentium 4 Northwood, 128 MB FX 5200, 74GB WD740 Raptor. Win7.

Re: Another poorly done recap job

thats not too bad... minus teh crap caps.

I've seen a lot of them, as well as many of the Dell toasters (SX270, SX280, GX620/520/745/755 USFF) roast pannies..... Pannies are tough, but not indestructible!

This. Panny FJs do seem to hold up better than ruby MCZs in these PCs, but they can still fail. The first one to go is usually the one in between the DIMM slots and AGP slot (probably because the two MOSFETs next to it get hot enough to discolour the PCB under it. The UCC PSC Poly I put there should handle it, though.

Re: Another poorly done recap job

Has something been pulled off C121 in pic 2, or is that just where the soldering iron has disrupted the solder on an empty pad?

C121 was never installed in the first place

Re: Another poorly done recap job

i noticed while using my 270 yesterday the 10k raptor is running at 50c, hope it holds in there. chegge what was the cpu in your poly modded system? I think thats a awesome mod how is the stability?

Re: Another poorly done recap job

I'm pretty sure it was a P4 2.8 with a Northwood core.

Re: Another poorly done recap job

What's the green slot? Doesn't look like PCI-E, and I thought AGP was always brown?

Seen green, orange, red, blue...

AGP.....Dell has to be different....but I've seen them all kinds of rainbow-like colors...

What the HEC?!

Yeah, that's not a very good recap job. But you are right - at least they used flux and the soldering doesn't look terrible. Mind you, mine looked worse... but I only had a 35W iron at the time and a heat gun. This is my ghetto recap, if any of you remember:

Here's the whole thread too:
https://www.badcaps.net/forum/showthread.php?t=20102

Eventually re-did it though. Changed the 1000 uF Nichicon HMs on the VRM low with more Chemicon PSC polymers, along with that red Apaq polymer. Still a work-in-progress, though. I have a 3 GHz Press-hot waiting to go in that machine .

The first one to go is usually the one in between the DIMM slots and AGP slot (probably because the two MOSFETs next to it get hot enough to discolour the PCB under it.

Yeah, that MOSFET runs insanely hot. Last time I checked it with my fine-point type-K thermocouple, it was running well over 70C case temperature. The cap next to it (Panasonic FJS) wasn't much cooler either. I think I might change it for something else too. Or add a heatsink on that MOSFET. Foxconn did a crappy design here.

Re: Another poorly done recap job

crappy caps... but soldering still not as bad...

Re: Another poorly done recap job

KZG and HEC caps on a GX270?How didn't they blow up like fireworks on the 4th of July?

momaka,I have to say,the soldering job in there is billion times better than mine.
The only thing I was able to recap until now and have it look good was a old half-broken 64 nVidia FX5200 video card,on which a cap broke and I put a TEAPO I had around in there.It was outputting garbage though,because I broke a SMD component off (ceramic cap most likely)
Was still fun to try and see if it boots.
I'm going to try and recap my A7V8X-X to see if it boots (I let you all guess what company made the 1500uf 6.3v caps on it.The name starts with N and ends with -on)and also my Radeon 7000 (this one will run with 2 different 1000uf caps:1 Teapo & 1 Rubycon YXG)

Make a new thread and post some pics. Graphics cards are fairly straight-forward. If you're getting garbage on the screen both in 2D and 3D, you might have knocked off an SMD resistor for the RAMs. Repairable, usually. If it's a SMD ceramic cap, even easier - just borrow one from something dead.

Nichicon?
