Advanced Practical CRT Monitor Repair Course

monitor repairing

Course Code: APM01

Course Length: 3 days


This course is introduced to individuals to the opportunities and challenges of monitor repairing. Participants will see how monitor repairing can be challenging, but they will learn how to address these challenges by employing appropriate tools and testing equipments to troubleshoot monitors. Through demonstration and hands on practices, participants will know how to use the right tools and test equipments to diagnose a monitor. This is an advanced course designed to provide a full understanding in troubleshooting and repairing monitor .


The Advanced Practical CRT Monitor Repair Course is targeted at IT Managers, IT Engineers, IT Lecturers, Technicians, Technical College Students, Electronic Hobbyists, and Computer Owners.


At the end of the course, participants will be able to:

  • Troubleshoot the Power Supply circuit.
  • Troubleshoot High Voltage Circuits.
  • Troubleshoot Horizontal Circuits.
  • Troubleshoot Vertical Circuits.
  • Troubleshoot Video (colour) Circuits.
  • Troubleshoot Cathode Ray Tube (CRT).
  • Troubleshoot Microprocessor and EEprom Circuit.
  • Troubleshoot Monitor Controls.
  • Use an oscilloscope to diagnose and repair monitor problem.
  • Use a Flyback Tester to check the monitor’s flyback, switch mode power transformer, B+ and yoke coil’s winding.
  • Use Blue ESR meter to check for electrolytic capacitor problem in a monitor.
  • Use high voltage probe for measuring the anode and focus voltage of a Flyback Transformer.
  • Use a Digital Capacitance meter to measure the internal capacitance of a flyback transformer.
  • Use an EEprom Programmer (Copier) to copy EEprom data of a monitor for troubleshooting purposes.
  • Use a CRT tester to check the condition of a picture tube.
  • Read the specification of a picture tube and find an equivalent tube for replacement purposes.
  • Use a light bulb to isolate monitor problem (power supply and B+ circuit problem).
  • Read Horizontal Output Transistor (HOT) and Field Effect Transistor (FET) specification and find a suitable equivalent number.
  • Diagnose and repair most of the monitor problem covering from 9”, 14”, 15”, 17” up to 21” monitors and many more.
