Repairing Defective Motherboards

This is a Video clip showing how to spot defective capacitors on a motherboard. An excellent source for ordering replacement capacitors suitable for desktop motherboards is www.badcaps.net
Here you will find these specialized capacitors with very low ESR, high ripple current, and low leakage.
This motherboard was suffering from 7 defective caps as well as the "Nothbridge" SIS Chipset - the heatsink was never really securing tightly onto the motherboard due to a missing clip-anchor.
A "22AWG" wire was used and soldered in place of the non-existant anchor.

Precision Division specializes in circuit-level laptop motherboard repair. Repairs are performed at a computer controlled dark infrared rework station and monitored by continuous ESD event detection. BGA glues are chemically removed prior to rework.

A thermal management solution is then implemented to help the system run cooler.

good job, i have been a component level tech most my life, i am very good at doing things i am told cant be done. people who can think for them selves wont be stifled by others telling them "it can not be done" we need more people like this guy who dont just give up cause some sales man said can't be done.. right on man..

Motherboard looks like a little city o.O

@scaleop4 Probably Chinese in origin. Defective or low quality capacitors (85 degrees Celsius tolerance) have only half the lifespan of high quality capacitors (100+ degrees Celsius tolerance). What happens is the electrolyte evaporates inside the capacitor.

Some Taiwanese companies in the early 2000's started to use Japanese electrolyte formulas (corporate espionage) but didn't have all the additives. Hence the higher failure rates of non-Japanese capacitors. I bet this is the case here.

why is it allways the green caps that go i have noticed this in a lot of old motherboards.

i don't know what the make of then are but they must be crap,.

Hah.... I have computer from November 2001. It had defective capacitors (in 2005), i changed it and...... It's now 2011 and it still works :). Everyone who don't know, If you have problem with computer, check capacitors. It's common problem with motherboards (I think it's common).

@MetallicBill Oh i just realized, my relative who gave me his computer replaced the motherboard but it was in a emachines case. I forgot about that. Thank you now I can upgrade the motherboard. : )
