Transistor / MOSFET Tutorial: basics how to use

today i share what i've figured out so far about transistors. this has been an issue that has stumped me for years and nobody that i've seen has made a very good way of showing how to use them. so i hope i've made a video that is a bit more useful. oh and yeah i'm prolly wrong about the NPN and PNP part. but oh well.

How to check fuses, diodes, transistors, mosfet, voltage regulators in circuit and out of circuit boards, if TV doesn't turn on or has no red standby light then check the power supply fuses. Some fuses can blow out during a surge or lightning strike or shorted diode or transistor goes out.
