How to Repair Electronic Equipment



You must know how to test and measure electronic components. There is no benefit to you even if you can identify faulty identification on the equipment if you do not know how to check and measure basic electronic components.


Assuming you've found that the vertical portion of one of the horizontal lines on the screen is responsible, but since you're weak at electronics component testing, challenge checking, or even scope checking, the percentage of your ability to repair Monitor wins shouldn't be high.


Must be able to test and check electronic components accurately by doing a lot of practicum and reading more information about electronic components both from repair books and from the internet. You have to pass the test first before going any further.


Second, no matter what type of electronic equipment you repair, it will always start with "how electronics work." If you don't know how the equipment works or how the equipment works, you will lose money and may not be able to repair it at all. there is this example, if the Monitor problem is in the horizontal section and you conclude that the problem is in the vertical section, you will lose a lot of time looking for the faulty section where the real cause of the problem is.


Horizontal section. In other words, if you don't know how electronics work, you won't know where to start with repairs.


This scenario is very common among beginners who are just starting out in the repair field. To solve this problem, bring the electronic board back home or wherever you feel comfortable where you can analyze the electronic circuit slowly.


Ask yourself these questions like "why does this board need to have an optocoupler in the power supply"? What is the function of optoisolator for overvoltage or overcurrent protection etc? What is the optoisolator part number? What does this optoisolator contain and how do I test it to see if it is good or bad? What will happen if the optoisolator is shorted? Will it cause the power supply to die, produce low power or even flash power?


Hope you understand what I mean. By asking yourself questions, you are actually training your mind to understand more electronics (in the case above it is an optoisolator). Use this method on any other part of the circuit on the board and I'm sure one day you'll really understand the electronics you're trying to fix.


If you can't find an answer, look into e-books, electronic forums, or simply search the internet from a different search engine (we have google.com, yahoo.com, msn.com, ask.com, etc.) for answers. . What do you want. .


Third, you need schematic diagrams to support what you are trying to understand about electronic equipment. If you want to understand how an LCD Monitor works then you should buy or download a free LCD Monitor schematic diagram and start practicing how each circuit works.


Divide the circuit into sections so that we have sections for the power supply, inverter, LCD panel, mainboard, etc. Study and understand each of these sets and ask questions as described above. Likewise this example applies to you if you want to repair a Plasma or LCD TV or other electronic equipment.


Fourth, Invest in You - Invest in yourself. Note that the first rule of investing is "invest in your business" or anything but yourself. While it is important to invest and reinvest in your repair business, investing in yourself is your first priority in investing.
