Possible Causes Of Input Switching In LG OLED TV
There are several reasons why your LG OLED TV may keep switching inputs on its own. Among the most frequent causes are:
Remote Control Interference
One possible cause of input switching is remote control interference. If you have multiple devices connected to your TV, such as a cable box, a gaming console, and a Blu-ray player, and all of their remote controls are in the same room, they may be interfering with each other.
Pressing a button on one remote may inadvertently send a signal to another device, causing your TV to switch inputs.

Automatic Input Detection
Many LG OLED TVs are equipped with automatic input detection, which means they can detect when the TV is connected and automatically switch to the default input.
Therefore, you must navigate the LG TV settings and turn off “Auto Device Detection.”
Faulty HDMI Cables
Another possible cause of input switching is faulty HDMI cables. If the cable connecting your TV to a device is damaged or not properly connected, it may cause your TV to switch inputs or display a blank screen.

Power Fluctuations
Power fluctuations can also cause your LG OLED TV to switch inputs. If the power supply to your TV is unstable, it may cause the TV to turn off and then turn back on, which can result in input switching to default mode.
Solutions to Input Switching
Now that we’ve explored some possible causes of input switching on your LG OLED TV, let’s look at some solutions to resolve this issue.
Check Your Remote Controls
If remote control interference is the cause of your TV’s input switching, you can try to resolve this issue by separating your remote controls.
Try placing them in different locations or using a universal remote control that can control all of your devices. You can also try covering the infrared sensor on the devices you aren’t using, to prevent them from receiving signals from other remote controls.
Disable Automatic Input Detection
If your TV’s automatic input detection is causing the input switching, you can disable this feature.
To do this, go to your TV’s settings menu and look for the option to turn off automatic input detection. This may vary depending on the model of your LG OLED TV.
Check Your HDMI Cables
If faulty HDMI cables are causing the input switching, you should check all of the cables connecting your devices to your TV.
Make sure they are intact and not destroyed. Replace any damaged cables you locate with new ones.
Use a Surge Protector
Power fluctuations can also cause input switching. To prevent this, you can use a surge protector to stabilize the power supply to your TV.
A surge protector can also protect your TV and other devices from power surges and lightning strikes.
Reset Your TV to Factory Settings
If none of the above solutions work, you can try resetting your LG OLED TV to its factory settings. This will erase all of your settings and preferences, so be sure to back up any important data or settings before resetting.
To reset your LG TV to Factory Settings, go to the settings menu and look for the option to reset to factory settings.
Contact LG Customer Support
Lastly, you should contact LG customer support for further assistance. They may be able to provide more advanced troubleshooting steps or offer a repair or replacement if your TV is still under warranty.
