How To Test MOSFETs In Circuit Using A Multimeter
Learn Electronics Repair
View ChannelAbout
Hi, Welcome to my channel. My name is Richard and I aim to teach you all about Electronics Repair. I am a hobbyist repair technician with over four decades of experience in a variety of different repair fields. Previously I worked full time in Component Level Repair and I learned to repair a wide variety of electronics with no schematics. Nowadays I mainly buy faulty electronics to repair then sell, especially Motherboards, GPUs and Vintage Computer items. I make videos ranging from beginners tutorials, techniques such as soldering and BGA rework, to real life repairs where I try my best to explain the actual fault finding process in detail. There are no rehearsals or dry runs here, this is REAL REPAIR. I hope you join me on this journey If you would like to help support this channel you could consider donating or subscribing on my patreon page. https://www.paypal.com/paypalme/youtubeLER https://www.patreon.com/learnelectronicsrepair DISCORD: https://discord.gg/vam6YC8vwU
