Your simplistic teaching is something surprisingly lacking from just about every other trouble-shooting video. Every other video assumes you know every basic without any explanation. You deserve so many more subscribers than you currently have

My goal is to make troubleshooting accessible for everyone, regardless of their background knowledge. Your support and encouragement mean a lot, and I truly appreciate it.

The inductor broke off now I'm having white screen

[@electronicsrepairbasics_erb]

A broken inductor can definitely cause display issues like a white screen, as it plays a critical role in power delivery to various components. I recommend checking the affected area for any further damage or missing components and replacing the inductor with one of the correct specifications. If you need further guidance, feel free to share more details, and I'll do my best to assist

[@Panda2DWorld]

@@electronicsrepairbasics_erb it's a Lenovo g550 the indictor is by the LCD port named l6

[@electronicsrepairbasics_erb]

Thanks for the additional details. In the Lenovo G550, the inductor labeled L6 by the LCD port is crucial for the display power circuit. I recommend checking the surrounding components, as damage to this inductor can affect other parts of the circuit. You should replace the inductor with one of the same value and specs, be sure to refer to the schematic or boardview file for the exact details. feel free to ask

[@Panda2DWorld]
