3 Basic Electrical Wiring Simulated Faults.
Electrical Troubleshooting Introduction.The TSTrainer certificate course includes training modules on. This will be evidenced by the successful completion of the increasingly complex electrical troubleshooting simulations. Upon completion, the technician will display skills in methodical electrical troubleshooting and PLC fault-finding techniques.
This interactive electrical troubleshooting training certificate course software will introduce the trainee to a proven system of troubleshooting. The skills of the competent technician must include a methodical means of troubleshooting and root cause analysis. The TSTrainer is designed to assist industrial electrical contractors, maintenance technicians, and other learners with systematic troubleshooting skills. The electrical problems start with basic electrical wiring and move up to PLC examples. The electrical troubleshooting examples in this TSTrainer certificate course will help sharpen your electrical installation testing skills and also includes introductory PLC troubleshooting training modules.

He uses his methods to accurately check on many electronics components with the help of few different meters. If you would like to be good in checking electronic component, I can recommend Jestine’s Ebook.
Some you can check on board, some you need to test it off board and some will tend to breakdown when under full load.
Once the components were replaced and powered On, the LCD TV came back to life.Ĭonclusion- You need lots of testing components skills to be able to understand the characteristics of electronic components. Why not replace it than to worry it will come back later for repair? A repeated call by customer will always be a non-profit repair. The reason I replaced the working components is because from experience, these component although are good at time of testing, it can go bad later. I proceeded to check on other components in the power primary side and found the current sense resistor was open circuit too.Īs a precaution measure, I also replaced three working components ie Optoisolator IC, TL431 IC and a filter capacitor. With visual inspection I saw the main filter capacitor already bulged as seen from the photo below:Ĭhecking on the power FET on board found it to be shorted.
The first thing to check was obviously is the main fuse and it was open circuit.
