How Do I Avoid Boards With Bad Caps?
Hi, I've decided that I'll find a place that sells Dual Socket 370 boards, after a failed MSI 694D Pro2 recap. I'm looking at the Asus CUV4X-D - is this board known to have bad caps? Ideally I'd prefer one with onboard VGA/LAN, so what do people think about the Intel STL2? I need more than 1 IDE slot, but I guess I could always turn to a PCI RAID adapter. -
Soldering Headphones Jacks - Apple Motherboards
Hi, I just bought a 'dead' PowerBook 867MHz Aluminum logic board cheap for one of its headphones jack. Recently my PowerBook jack must have crapped o ut and makes the computer think headphones are always plugged in. This means that my internal speakers are always muted unless I stick my iPod earphones into the jack about half way.
I tried heating the jack with the conical soldering iron I usually use with PC motherboards and all I see are either bubbles or nothing. The joint does not seem to come loose. Is Apple using a different based solder? What can I do? -
Re: MSI 694D Pro2 - Does Not POST After Recap
Yep, that's where i bought them. -

> did the board work before the recap?
Yep
> coldheat iron=crap. the money youi wasted on it would buy you a dmm. return it if you can.
Doubt I could; Hong Kong works differently than North America - the shop comes before the customer =\ So even though I pay much less for Rubycon capacitors (see other thread) I suffer crap customer service and no aftersales service. I should've just waited till I flew back to Canada before buying the cold heat.

Re: MSI 694D Pro2 - Does Not POST After Recap
Edit: I just thought what I did different. I tried out my new Coldheat soldering iron (I knew it wasnt a good idea
) - would the sparks be what caused the VRM to fry?

Re: MSI 694D Pro2 - Does Not POST After Recap
Thanks for your replies. Do these VRMs just break by themselves? I've taken great care in removing and replacing components to not knock other parts of the board.
Is there anything I can test without buying a multimeter? I'm a newbie when it comes to electronics. And with the 20 or so pins the VRM has, which two do I put a voltmeter in parallel to?Last edited by opaque; 07-07-2005, 01:28 AM.Leave a comment:

Re: Soldering Jacks? Advice Would Be Great!
Apparently since Silver has a higher melting point, would I need a different soldering iron?Leave a comment:

Re: Soldering Jacks? Advice Would Be Great!
Hmm I tried it again and now I see bubbles when I apply the soldering iron. Is this a different type of solder?Leave a comment:

Re: Soldering Jacks? Advice Would Be Great!
I just tried desoldering one of the joints on the board. It seems different from desoldering a normal PC motherboard - even with a heated iron the solder doesn't seem to melt. The solder seems glossier too. Any hints?Leave a comment:

Re: MSI 694D Pro2 - Does Not POST After Recap
Thanks for the advice, Randy... What are VRMs?
i've never used a multimeter on computers before - only in Physics labs. Do I just power on my machine and bridge the voltmeter across two nodes so they are in series? What should the voltages read?Leave a comment:

MSI 694D Pro2 - Does Not POST After Recap
I just recapped my board with Rubycon MCZs - when I flick the power switch, the 4 LED lights in the bracket at the back go RED (Manual says CPU problem - but the CPUs worked beforehand). Fans on CPU spin for a second then spen down. I've tried using just one CPU. Any clues? Thanks -
Re: Soldering Jacks? Advice Would Be Great!
I live between Canada and Hong Kong; right now, I'm in Hong Kong so that probably won't work.
Another option I've read up on is to use my solder sucker. Would that work? Why does Badcaps not recommend using the sucker more than twice on the same hole? Does it mean if I desolder one point with the sucker twice, I should never use it again even with new solder?Leave a comment:

Re: Soldering Jacks? Advice Would Be Great!
But the solder points cool so quickly. As soon as I move onto heating the next point the first one will cool down...Leave a comment:

Soldering Jacks? Advice Would Be Great!
Hi, I'm doing a soldering replacement for my Apple PowerBook's headphones jack. I ordered a broken motherboard of the same PB off eBay and saw that it has 5-6 soldering points like

With capacitors, I heated one side and pushed the rest out, but that won't be possible with this, right? How would I go about doing this?
Thanks!
(P.S. my existing one has a bad sensor that makes my PB mute because it thinks headphones are plugged in even if they arent and Apple is asking for US$500 + $100 labor for... -
Re: Recapping A Board With Different Capicitance Caps?
That's the beauty of living between Hong Kong and Canada
... I'm using the Rubycon MCZ series (again, I used them before with a different MSI board too) and for the 100uF 10V one they didn't have Rubycon in stock so I'm using the Sanyo organic or wahtever it's called.
If you buy in bulk, you can get 10 pcs for $19-25 HK (about US$3-3.50). I know the shop is not selling fakes because they're very reputable (especially when it comes to selling Silverstone and Zalman stuff)....Leave a comment:

Re: Recapping A Board With Different Capicitance Caps?
Heh, that was just an example... I'm replacing the 2700uF, 6.3V's with 3300uFs, 1500UFs with 2200uFs, and 330uF 16V with 470uF 16V.
Those are the closest upwards the store sells - and very cheap too... HK$20 for 10 on most (that's about US$3 for 10)...Leave a comment:

Re: Recapping A Board With Different Capicitance Caps?
Cool! Just checking... Thanks! I'll get 470uF's for the 330uF's etc,.Leave a comment:

Recapping A Board With Different Capicitance Caps?
Hi, I've recapped a couple of boards successfully before, but this MSI 694D Pro2 board I've had for 4 years 24/7 has developed bulging caps and the local store that sells Rubycon / Sanyo Organic caps doesn't sell exactly the ones i need.
Is it safe to replace capacitors with a higher capacitance? I understand the voltage must be exactly the same right? e.g. I need 1000uF 6.3V caps, can I replace those with 3300uF?
The shopkeeper says I can replace my 2700uF 6.3V capacitors with 3300uF 6.3V and it'll be fine. I'm a bit skeptical and would like some feedback.
