REPAIR TECHNIQUES COMPONENTS AND
RESISTANCE VALUES
MEASURING THE COMPONENTS FROM THE ELECTRONICAL
CARD
You might measure the components either connentors of electronic card or directly on the
component.
Measuring from the connectors of electronic card gives definite result to define the repair. If you
know the specialities and values of tester, you can easily determine the repair.
