Smart TV manufacturers deliver their models with calibrations that the manufacturer himself deems appropriate, however, the most expert eyes prefer to have complete control when it comes to calibrating the image and managing all the parameters of their TV. For that reason, access codes to secret menus and service menus are tremendously valuable to many, so we are going to review some of them that could be useful to you.
Be careful with touching
The first thing you should keep in mind is that if you touch too much you could mess up parameters that will directly affect the performance and operation of your Smart TV, so if you don't control it, you'd better forget these menus.
HDMI Signal override
This menu allows you to adjust parameters that directly affect the signals received through the HDMI ports. One of the most interesting is the one that adjusts the colorimetry profile, being able to choose between Auto, BT709, BT601, BT2020 and P3 D65. To access it you have to do the following:
- Open the Home menu (house button) so you can see the usual start menu, with application icons and shortcuts.
- Press the settings button on the remote control
- Go to all settings
- Enter the image menu to move the cursor to the right column
- Press the following code with the remote: 1113111
The new HDMI Signal Override secret menu will appear immediately with the available options.
Service Menu
This menu is only accessible to technicians and qualified people, as it requires a special remote control to access it. This menu is especially sensitive, since there are parameters that could cause your TV to stop working. To access it you need a remote control with the technical service function, although there are Android applications that allow you to activate the menu through the local network.
In any case, there is an even simpler method, since by accessing a website from the TV browser, it can be activated immediately without complications. The website that must be accessed is the following:
Once inside, it is very possible that the TV will ask you for an access code, to which you will have to enter 0413.
VRR information menu
This informative menu is used to know at all times how the variable refresh technology is working. It is a small menu with information on the screen that shows information such as the current refresh rate, the resolution at which the image reaches and the included color profile.
To activate it you just have to press the green button on the remote control 7 times. The easiest thing is to continuously quickly press the button until the menu appears.
Hotel Mode
Hotel mode serves to limit many of the TV's functions, but we could also have HDMI1 always automatically selected when turned on, for example.
To enter this menu you must do the following:
- Press the settings button for approximately 10 seconds. First you will see how the settings menu appears, and then it disappears and shows a box with the name of the source you are in (HDMI2, for example).
- When the source name appears, press the code 1105 and press the OK button on the remote.
Various settings
This menu is very simple, but also very useful, as it allows you to adjust options such as resetting the AV settings, requesting remote assistance from LG, preventing the LG logo from appearing when turning on the TV or preventing the background image from being displayed. when no signal is received.
To activate it you just have to press the mute button on the remote control 4 times.
Diagnostic panel
The diagnostic panel shows everything that is happening on the screen, and with it you can know data such as the exact model of the TV, the system version, power supply details, very detailed information on the WiFi connection and details of the signal that comes through the HDMI.
To enter this menu you must do the following:
- Open the settings panel and enter All settings
- Go to the Channels panel
- Click on Tuning and channel configuration
- Press button 1 a total of 5 times for the menu to appear.
