It would be interesting to see the entire board and also the items which you believe have been replaced. I just ordered the three cylindrical capacitors, but I didn't know that the pancake capacitors were also replaced.

I didn't do my pancake ones, and I also have a wiring diagram I can send you for those three cylindrical ones that need replaced!

If you know how to do it and it's not too big, please share the diagrams and pictures with us also.

Franklin2 and comtb: I was going to convert the diagram to a .jpg and insert it in line. comtb, if you know how to do it have at it, but I don't think you have enough posts here to have privileges to post photos yet, so I am happy to do it for all of us once I receive it.
My capacitors just came in the mail.
And what do you guys think of this soldering station:
4 in 1 x Tronic 8080 XTS Hot Air Rework Soldering Iron Station DC Power Supply | eBay

These are discrete components not SMD's.
Anyone with a steady hand can do this with a simple 30W soldering iron and some wick.
If you spend a good amount of time working on *modern* electronic devices (fixing cell phones, tablets and motherboards) then it might be a worthwhile purchase.

Something like this works much better to get the solder out, especially if it's a double sided board.

I did mine with a cheap plugin soldering iron and a bulb to suck the old solder away. Just use a well lit area and a steady hand like ardwrkntrk said. If i remember, the smaller cap of the three was very close to another lead on the back of the board, so make sure not to short the leads with the new solder.

The caps you're looking to replace are c2, c4, and c111
I should've taken pics when i replaced them so you can see the location on the board... but I forgot.

I just finally got my computer out and am looking for a torx driver to open it up and inspect and take pictures.
These are the capacitors digikey shipped me:
CAP ALUM 47UF 25V 20% RADIAL - P/N P14411-ND
CAP ALUM 10UF 63V 20% RADIAL P/N P13467-ND
Are these what I need? I got two each.

Tim,
The above device is commonly called a solder sucker.
A few bucks at RadioShack or some place like that.
I just use copper wick myself, but I have been soldering since childhood.
I think you'll only need one of the 10uf caps, but the ratings seem fine.

Look up "desoldering tools" in a search on the web. They have all kinds of stuff. That thing I posted has a teflon tip, and it's spring loaded, you **** it against the spring and when you get the solder hot you hold that down near the solder and push the trigger, and it sucks the solder right out of there.
