Samsung Television Error Codes: Comprehensive List

Samsung TVs display error codes via on-screen messages, LED blinking patterns, or diagnostic menus to signal hardware, software, or network faults. These codes help technicians pinpoint issues like power supply failures or Smart Hub glitches without full disassembly.

Access codes through Settings > Support > Self Diagnosis on most models (2015+). Older units show LED blinks at the bottom red light. Fixes range from power cycles to board replacements.
