Blinking blue light, no picture, or sudden shutdown — most faults are fixed without replacing the console.
1. Blue light blinking — no picture: Most often the HDMI chip or motherboard. Component-level repair often costs far less than a new console.
2. Shuts down mid-game: Overheating — built-up dust or dried thermal paste. Cleaning and repasting bring the silence back.
3. Won't power on at all: Usually the PSU or electrical protection. We diagnose with gear, exact price before starting.
