look at ur multimeter. put ur pointer at x1. now use ur test points as said above. press power button,meter should give some reading if not then power switch is defective(open). better to take basic electronic class somewhere before entering in mobile world.

I can flash .... unlock ... change IC's like UEM, UPP, PA etc etc ..... do soldering repair or jumpers ..... i know about testing power buttons but i don't know the exact reading that should come up .....

as abhishek aga said .... 1 to 10 but when i set the multimeter at 200 (ohms) it says 0.04 so is this right ?
