Electronic Schematics Diagram - The Four Commonly Asked Questions
I met a number of questions on the electronic circuit diagram schemes.
Most of the questions are:
a) Do we really need a schematic to repair any electronic equipment?
b) The schematic diagram help us to repair faster?
c) At where we can get a schematic diagram in particular?
d) How read the schematic?
Well, the answer is:
a)-Theoretically yes, practically not necessary, it depends how good you are in electronic repair knowledge. For a beginner a 'must' for you to understand about schematic diagram, since little little more knowledge gained automatically depends less on schedule. Definitely need a scheme when he meets a new design or technology. For example, when it comes to CRT monitor repair i seldom see schematic because I already knew most of the circuits and the section in a CRT monitor. New technology such as LCD or TFT monitor makes me temporarily is based on the schematic. As my knowledge of LCD monitor repair grows gradually go depends less on the schemes. May be my situation is different from yours because I'm concentrating on just one type of equipment. I've seen a lot of workshops in my country that repair many types of equipment such as TV, VCR, VCD, DVD, amplifier, stereo, fax, laser printer, microwave, etc. The most likely need schematic diagram to keep them current on each of the technological equipment.
b) If you have a schematic for every team in particular your troubleshooting time can be reduced by half! Unfortunately many manufacturers do not release the equipment layout diagram. If you rely too much on schedule to be stuck on how to repair that particular equipment. Why with schematic diagram you can repair any computer faster? Because a schematic diagram shows that all the part list, waveform, voltages, explanation of how that particular equipment work, block diagram, schematic design, the number component part, electrical schematics symbols, substitution, modification (if have) and electronic schematic symbols, etc. Assuming you have a power supply section blown and could not recognize the part number, but you will be able to scheme to find the exact part number and finally repair equipment.
c) If you work in the factory or your local team will have the schematic diagram for the model they sell. Any below assurance unit that comes in you will be able to diagnose and repair the equipment fast. This will enhance the reputation of the company and customers referring their friends Fast service on that particular brand of equipment. You can also get schema in the form of a book of local electronics stores. Usually it is a compilation of the few brands and model of a special electronic equipment. Tv television or chart patterns are easy to get, but the diagrams and computer monitor radio schemes amplifier is a little harder to find. If you have the budget get one of the books. Third, since most of us already know you can download electronic chart patterns online. Free TV schedules is easy to find on the internet. You can also buy the format of 'CD'. This investment will usually be paid soon.
d) As to read schematic, am unable to show you through article since you need a real plan to make you understand. Reading scheme is not so difficult, provided you have some basic knowledge of electronics. I have some suggestions:
-Ask a friend who is in line repair
-Take short courses in electronic repair and ask the teacher
-Buy books at your local bookstore on "read schematic diagram"
-Buy schematic diagram and learn on their own (ie will sometimes, but worth it)
-Fix some project kit with the schemes given electronic kit. This will add to their knowledge as well.
Conclusion: In order to become an electronics repair shop successfully you must understand how to read schematic.
