The VESA Nightmare: Fixing Threads in a Sealed PSU
Imagine trying to mount a high-end monitor only to realize the internal threads on your power supply case have vanished into the unit’s abyss. This episode tackles a high-stakes mechanical challenge: repairing a "blind hole" in a sealed power supply unit (PSU) that cannot be opened due to lethal electrical charges. We break down the engineering behind self-clinching PEM nuts and why they fail under the leverage of modern monitor arms. From the dangers of metal "swarf" shorting out circuits to the structural limitations of soldering, we explore every angle of this hardware headache. Listeners…
