PDF compilation of service menu access codes for LCD and LED televisions, apparently collected from a Soft4LED source, about 203 KB. Although filed as a schematic, it is a reference list rather than a circuit diagram, and names no specific TV brand or model. Technicians use such codes to enter factory or service modes for adjusting panel settings, resetting options, changing backlight values or reading error logs. Treat entries with care: incorrect service menu changes can disable features, so note original values before editing.
