The SoC runs hot. If you remove the heatsink during diagnostics, make sure to clean off the old thermal paste and apply a fresh layer before reassembling the unit. Provide volatile high-speed memory caches used during video

: Place your multimeter ground on a chassis shield and measure the large surface-mount inductors (coils) scattered across the board. You should find distinct 5V, 3.3V, and low-voltage core power lines. A missing rail points to a failed buck converter chip or a shorted decoupling ceramic capacitor nearby. The Boot-Loop or Red Power Light Hang If you remove the heatsink during diagnostics, make

Controller lines supporting hard drive data and power delivery, alongside USB and Ethernet network interfaces. Critical Zones in the DS-80249_P Rev 1.2 Architecture

: Features a central processing unit (CPU/MCU) typically found under a heat sink for thermal management.
