    Stop conditions
    • If any issue involves live-voltage, you must immediately stop and escalate to a qualified technician.
    • If fuse replacement fails repeatedly, do not attempt further replacement and escalate to a qualified technician.
    • If you suspect incorrect voltage levels, this requires diagnosis by a qualified technician.
    • If the power supply output is absent after checking upstream sources, a qualified technician must diagnose the power supply component.
    • If the wall outlet is the issue, contact facility maintenance; do not proceed with electrical work.
    • If the power cord is damaged, replacement must be handled by qualified personnel.

    Expected: Initial condition is documented before deeper diagnosis.
