Testing Horizontal Output Transistor
























































                   If you are repairing Television and Computer Monitor, I’m sure you had
                   seen a horizontal output transistor (HOT) before. This transistor is use to
                   switch the flyback transformer and prone to become defective due to the
                   stress of dealing with high voltage. A shorted HOT will usually caused no
                   power, low power, power cycling and power to shutdown. The HOT is
                   mainly a NPN transistor.
