On LG TVs In a Hotel

Some hotels enable the Hotel Mode feature which locks some of an LG TV’s features, including its input source. This mode is essentially a hidden menu that, in addition to making certain functions useless, also locks your remote’s Settings button. This function is only available on select models fitted with older webOS versions. TVs with webOS 6.0 and later do not support this function. 

While we advise against trying to disable this mode as the hotel may heavily fine you or take legal actions against you, there is a way to adjust the input without the remote’s Settings button. Since you are not technically disabling Hotel Mode Setup by adjusting the input this way, you should avoid getting caught or fined by the hotel staff. 

Step 1: Turn the TV on before finding and pressing the Power button, often found on the TV’s bezel below the logo. 

Step 2: Hit the Power button until the Input option is highlighted. 

Step 3: Then, press and hold the Power button once more to choose this option. 

Step 4: Quickly click the Power button again to move the highlight to your desired input. Then press and hold it to select it.

If you do decide to change your hotel TV’s input, just remember to revert it to its original input and settings before leaving the room so that the staff won’t suspect you of tampering with the TV. 

Head to the next section to learn how to access any blocked inputs on a hotel TV. Remember, you must re-lock any inputs you’ve unlocked before checking out of your hotel room. 

Can an LG TV’s Input Be Blocked?

Yes, you can block inputs on an LG TV. 

As previously discussed, smart TVs in hotels often have Hotel Mode (which is a service/hidden menu), that restricts their settings and can also lock certain inputs. 

Please note that Hotel Mode is not available on webOS 6.0 or later, and can only be found on some LG TVs with older webOS versions. 

However, there is a way to lock/unlock inputs on a hotel smart TV by following the steps below. 

On Older webOS Versions:

Step 1: Press and hold the remote’s Menu or Settings button (depending on the TV model) until HDMI is displayed in the top-left corner of the screen or until your TV asks for a passcode. 

Step 2: Use your remote control’s numeric keys to type 1105 into your TV. If this password doesn’t work, try one of these PINs: 0000; 7777; 0413; 8741; 8743; 8878. Then click OK

Step 3: Once you’ve entered the correct PIN, the Hotel Mode menu should appear on-screen. Then, turn it On to enable/disable any of the restrictions. 

Step 4: Head to the AUX Source Setting and disable all of the inputs except for the one you’d like to lock and use. 

Watch the video below demonstrating how to access Hotel mode and disable inputs on an LG TV.

6. Remove Your Remote’s Batteries

Your remote may be malfunctioning, resulting in the input changing by itself. To test if your remote is the culprit, remove its batteries and observe if your TV continues to automatically adjust its input. 

If your remote does end up being responsible for this issue, consider replacing it or having it repaired. 

LG TV Can’t Change Input

If you can’t change your TV’s input, it may be in Hotel Mode or having its settings blocked through another hidden menu. We recommend heading to the Can an LG TV’s Input Be Blocked section for more information and instructions on how to bypass this blockage. 

Wrapping Things Up

There are several ways you can change an LG TV’s input, with the easiest way being clicking the remote’s input button and using the TV’s Power button. However, you can also change the input via the ThinQ app by linking it to your TV. 

An LG TV’s input can be blocked if the TV is in Hotel Mode, though you should still be able to adjust the input using the TV’s Power button or by accessing the service/hidden menu. Just remember to change the settings back to the way they were before you check out to avoid getting in any trouble. 

If your TV’s input is changing automatically, disable some of its settings before soft/factory resetting it and replacing its remote.
