Comparing Defective Component With Good One

By on October 14, 2013

Is it possible to compare defective component with good one for doing servicing job? If so then we have to buy & stock all good components for reference….. which is IMPOSSIBLE.


It is not necessary to keep all parts for comparison.Example, I’m very familiar with LCD high voltage transformer winding value/result thus I don’t need to keep stock for it. If someone that is new in this field then he/she may need to keep some for reference. One more things is one can always check from forum or to ask a repair friend to confirm if a particular component is bad or good as this way you can save money¬† and no need to keep the parts.
