usually motherboard defect is capacitors

1. Identify first the busted capacitor ?
How-- look each capacitor which is deform or blown
2. See the Value of capacitors
How-- look closer to the capacitor write down the value
usually 6.3v 1500uf // note : if you cannot find same value change all the capacitor that have
the same value and it with the new value
//now you identify and get the value of the capacitor
3. Now remove carefully the busted one
using soldering iron
How -- simly put the tip of soldering iron into the led and when it melt pull the capacitor slowly
