The  Importance Of How to Diagnose A Problem In Electronic Circuit

I received lots of emails from my members or subscribers about how to troubleshoot a certain circuit but most of the emails were referring to power supply section. Some of the questions like “I have replaced these components but why it still won’t work”,” I have checked all the primary section components why there is still no switching”, “The output power dropped to half, how to solve it?” and etc.

Let me share a secret to you, if you want to be successful in electronic repair and solve a problem fast you must learn how to diagnose a problem first! No matter what type of electronic equipment you are repairing you must first learn how to isolate and diagnose the problem so that once you have determined that a particular circuit is at fault, you then can use all your testing electronic components knowledge to find out the bad components be it on power supply section or other sections like high voltage, horizontal, vertical, colour and etc.

The reason why you must learn how to diagnose a problem first is because I don’t want you to waste unnecessary time in troubleshooting a circuit which is in working condition. Let me put it this way, if you have complain of one horizontal line across the Computer Monitor screen, which section or circuit you want to check first? Do you want to check colour section, horizontal section, power supply section or even high voltage section?

Which section you want to check first? The answer is you should be checking on the vertical section before you touch on other circuits. Otherwise you may be wasting your precious time on checking a circuit that have no bad components in it! With just one wrong move the rest of the troubleshooting time will be gone and at the end you still unable to repair the fault.

You may ask “I have never repaired this type of equipment before then how should I know which section I have to check first?”  The answer to you is “preparation”! I believe you have gone through examination so before the exam date what would you do? Obviously you will prepare yourself in terms of group study, do lots of revision or even go for tuition am I right? This is the same principle applies to electronic repair. That’s mean you cannot simply guess which circuit is at fault, you should be able to diagnose and confirm indeed the particular circuit is at fault.

Of course you can guess but it will take you lots of time to solve a problem. In electronic repair we talk about “speed”. The different between an amateur and a professional is the speed and the capabilities in accurately testing electronic components, voltage and signal tracing.

The real key to success for a professional is that they are able to diagnose a problem fast and use their best knowledge to find out the fault in the defective circuit.

So what kind of preparation you must do in order to be good in electronic repair? You must understand how a circuit work in term of theory, join forum and ask questions, get schematic diagrams and analyze each of the circuit functions, buy electronic repair books to learn from other experts (different authors have different styles of solving a problem), communicate with other fellow electronic repairers and subscribe or buy electronic related magazines. All these preparation is a continuous work and may take up lots of your time but I can guarantee that these are the best investment you have ever made!

I always believe that to gain something you must sacrifice first in terms of your time, money and etc. Or you can have the option to enjoy your leisure time all night long everyday and at the end grumble why I do not know how to repair this or that circuit and then later you give up! If you want to be a good in your field you have to prepare yourself-it’s simple as that. Have you heard of these words before “If you fail to prepare you prepare to fail”?

Now every good electronic repairer has their own way to solve a problem but they have one thing in common which is diagnose the problem first! They could have been gained some tips or knowledge from the preparation work and they might even develop their own electronic gadgets or circuit to help them to diagnose a problem fast. Let’s take this for example, a Monitor came in with power cycling problem and the possible cause could be in the primary or secondary side.

In order to confirm which section is the cause of power cycling problem, he used a technique or rather I say with the help of a circuit or gadget he created that he is able to know which section is at fault. His whole concentration is on the suspected circuit and I believe he could easily locate the defective component fast and this could save him tremendous amount of time.

Do you know that you too could come out with your own way of testing or troubleshooting a circuit fast? In order to do that, again it comes back to “preparation”! The good news is that you could have your own troubleshooting techniques on different types of circuits if you wish to.Never stop learning, be creative, continuous improve yourself and with the mindset of never give up, I believe you could easily repair any electronic equipment fast and make money out of it and at the same time have fun in electronic repair. Wishing you all the best!
