Kontron 02004‑0005‑08‑02 GKD290052 is a fanless single‑board computer (SBC) motherboard featuring an Intel 800 MHz processor and 0 KB L2 cache, designed for continuous industrial operation in a wide temperature range. Common failure modes on this platform include power supply degradation (especially the 5 V rail), electrostatic discharge damage to the CPU socket or integrated chipset, and aging electrolytic capacitors on the main voltage regulators leading to brown‑out symptoms. First‑check diagnostics should verify that all input voltages meet specifications, inspect the board for bulging or leaking capacitors, and review any diagnostic LEDs or serial console output for error codes indicating power or boot failures.[oss-gpt-20b]
