On many modern televisions, there’s actually a secret menu that’s accessible using a cryptic button combination.
The so-called service menu grants access to hidden device settings that allow you to customize your TV as if you were a system technician. It goes beyond mere picture and sound, with diagnostic tools and picture calibration tools and special developer options.
The hidden service menus in TVs may look slightly different from manufacturer to manufacturer, but they usually offer the same sorts of adjustments and settings:
- Update: Update the device’s firmware.
- Calibration: Make precise and wide-ranging adjustments to screen settings, including color temperature and white balance.
- Display settings: Change sharpness and screen resolution.
- Audio settings: Manipulate the time offset between the picture and sound track (audio latency) or adjust the equalizer.
- Diagnostic tools: Run diagnostic programs or perform self-tests to detect faults with the speakers, connections, or display.
- Tuner settings: Make in-depth system settings on the TV tuner by manipulating signal amplification, adjusting search parameters, or making tweaks to frequency bands.
- Network settings: Set LAN and Wi-Fi connections, change the network configuration, or perform network diagnostics.
- Energy options: Tweak energy consumption settings during operation and standby mode behavior.
- Device settings: Reset to factory settings or lock certain features.
- Developer options: These settings are usually of little importance to end users. Developers may find these settings useful to test different features for compatibility or performance.
A quick word of warning
The service menu isn’t without risk. If you mess something up, you could theoretically cause permanent damage or even brick the device altogether, rendering it unusable.
In other words, you should only change settings in the service menu that you understand. Don’t tweak it willy-nilly. In fact, before you do anything, you should record all of the default settings so you can revert to normal operation in case something goes wrong.
Each TV manufacturer hides their service menu behind their own unique access code. Not all models from the same brand may have service menus that are accessible in the same way, either.
Sometimes you have to switch off the TV beforehand. Other times you have to hammer a certain button sequence into the remote control. Or maybe you just have to hold several buttons at once. Depending on your TV, the procedure will differ.
We’ve compiled the most common service menu access procedures for the major TV brands. For best results, use the original manufacturer’s remote control that came with your television.
Note: If you’re unable to access your TV’s service menu, you can contact the manufacturer’s support service and ask for the appropriate button combination. Make sure you state your TV model.
