| I came across quite a number of questions about | | | | Assuming you have a power supply section blown |
| electronic circuit schematics diagram. | | | | and you could not recognize the component part |
| Most of the question asked are:a) Do we really need | | | | number, but with schematic you will be able to find |
| a schematic diagram in order to repair any electronic | | | | the exact part number and finally repaired the |
| equipment?b) Will schematic diagram help us to repair | | | | equipment.c) If you work in the equipment's factory |
| faster?c) At where we can get a particular schematic | | | | or their distributor you will have the schematic |
| diagram?d) How to read schematic diagram? | | | | diagram for the model that they sell. Any under |
| Well, the answers is as below:a)-Theoretically yes, | | | | warranty unit that comes in you will be able to |
| practically not necessary, it all depends on how good | | | | diagnose and repair the equipment fast. This will |
| you are in electronic repair knowledge. For a beginner | | | | increase the company's reputation and customers will |
| it is a 'must' for you to understand about schematic | | | | recommend to their friends about the quick service |
| diagram, as you gradually gained more knowledge | | | | of that particular brand of equipment. You also can |
| you will automatically depends less on schematic | | | | get schematic diagram in the form of a book from |
| diagram. You will definitely need a schematic diagram | | | | local electronic shops. This is usually a compilation of |
| when you come across a new designed or | | | | few brands and model of a specific electronic |
| technology. For example, when comes to crt monitor | | | | equipment. Tv or television schematics diagram are |
| repair i seldom see schematic because i already | | | | easily to get but computer monitor schematics and |
| understood most of the circuitry and section in a crt | | | | radio amplifier schematics is a little bit harder to find. |
| monitor. The new technology such as lcd or tft | | | | If you have the budget get one of the book. Third, |
| monitor makes me have to temporarily relies on | | | | as most of us already know that you can download |
| schematic diagram. As my knowledge of lcd monitor | | | | free electronic schematics diagram from the internet. |
| repair grows, i will gradually depends less on the | | | | Free tv schematics is easily found on the internet. |
| schematics. May be my situation is different from | | | | You may also buy it the 'CD' format. This investment |
| yours because I'm concentrating only on one type of | | | | will usually pay back in the shortest time.d) As how |
| equipment. I've seen quite a lot of repairers in my | | | | to read schematic diagram, I'm unable to show you |
| country that repair many types of equipment such as | | | | thru article because you do need a real schematic |
| tv, video, vcd, dvd, amplifier, hi-fi, fax, laser printer, | | | | diagram in order to make you understand. Reading |
| microwave and so forth. Most probably they need | | | | schematic is not that difficult, provided you have |
| schematic diagram to keep them up to date on each | | | | some basic electronic knowledge. I have a few |
| of the equipment technology.b) If you have a | | | | suggestions: |
| particular schematic diagram for that particular | | | | -Ask from a friend who is in the repair line |
| equipment, your troubleshooting time can be reduced | | | | -Take short courses on electronic repair and ask the |
| to half! Unfortunately many manufacturer do not | | | | lecturer |
| release their equipment's schematic diagram. If you | | | | -Buy books from your local bookstore about the |
| depends on too much of schematic you will be stuck | | | | subject "how to read schematic diagram" |
| on how to repair that particular equipment. Why with | | | | -Buy schematic diagram and learn on your own (this |
| schematic diagram you can repair any equipment | | | | will take sometimes but worth it) |
| faster? Because a schematic diagram shown you all | | | | -Fix some project kit using the electronic kit |
| the part list, waveform, voltages, explanation how | | | | schematics given. This will add to your knowledge |
| that particular equipment work, block diagram, | | | | also. |
| schematic design, component's part number, electrical | | | | Conclusion-In order to become a successful electronic |
| schematics symbols, substitution, modification (if | | | | repairer you must understand how to read schematic |
| have) and electronic schematic symbols and etc. | | | | diagram. |
