Kurzschluss kurz nach Garantie: Ich wage die Reparatur!

🔧 Smartronik Repair Service (Advertisement) ➡️ https://www.smartronik-repair.de/ A Geekom Mini PC stopped responding completely shortly after the three-year warranty expired, and the power supply completely failed when the power adapter was plugged in. In this repair video, I investigate the cause of the power failure and demonstrate step by step how to systematically troubleshoot the problem at the board level. Using a multimeter, continuity tester, and thermal imaging camera, we pinpoint the exact culprit on the motherboard: a microscopically small, short-circuited capacitor caused the total failure. After precisely desoldering it under a microscope, soldering in a new component, and reapplying the thermal paste, we perform a functional test. The subsequent boot test also reveals a very interesting characteristic of mini-PCs when no hard drive is installed. Learn in this tutorial how micro-soldering and structured measurement technology can even save seemingly dead electronics. ________________________________________ 📢 Transparency Note: This video contains self-promotion (referral to my website) and affiliate links.
