Motherboard ASRock came back to life
The Motherboard of this story is an ASRock KBNF4G-SATA2 and was brought to me from a co-worker; he came very desperate because it was out of order: no video out.
Let’s have a look first, I told him.
When it was checked on, guess what?
Five bulged e-caps were seen
The five bulged e-caps were de-soldered from the circuit: 3300µF/6.3v.
They were substituted for similar, and when the Motherboard was turned on, look at the result below:
As you can see the Motherboard was saved from the dump. Mission accomplished.

Hi,
Nice article. I have done this kind of repairing the motherboard many time. I also change the cap, but if you didn't change all the cap the customer will come back to you soon because also the other cap will be blown.
Best regards, Peter

Well Peter, I use to check on all the e-caps with the Blue ESR Meter, then I only change those which have high ESR.

So much to go wrong on any MB.
Here you were rewarded for having a go at repair.
I guess a repair does not get much simpler that replacing bulged caps.
Well done!

Mr. Humberto Rodriguez,
Why are you using a FAKE photo of yourself ? Anyone can see your legs don't cast a shadow on the floor, like the legs of the table do. You look like floating above the floor like a ghost. The only real thing in that photo made in Photoshop is your face. The body isn't yours, nor the clothes, nor the house. It is not a shame to be poor, as long as you're honest. Everybody knows you don't get rich repairing cheap ASROCK motherboards...

while that is true to change other caps so that the customer doesn't return soon, would the customer be happy to pay the extra charge?i hope so.
good job of saving from the dump.

Well mobydick, I think is not too difficult to get some similar e-caps.

Well, I remove these e-caps with a soldering iron of 40 watts. For connect the new ones you have to clean the holes in the Motherboard, I use a steel wire (the tin does not fix on it), and then introduce the pins of the capacitor and weld it with fresh tin.
Note: I recommend to test the ESR of the new caps with the Blue ESR Meter or similar
