Answer / eduard

its simple to check them electronics component... first,we
have called capacitance meter for "Capasitor,you can check
for leak and faulty, capacitance means uf (micro farad.two
types of faulty "Capasitor, Leak and called white subtance
oszing. "Daiode you can check faulty the two terminal when
its test to polarity forward/reverse has continuity mean
Shortage. 500ohms good below 500ohms means leak.
