External ports on your LG television are a handy feature that extends your device’s usability. However, if these ports fail, the TV will often show error messages or switch inputs independently. Luckily, fixing these HDMI and input problems isn’t too challenging! Show
If your LG TV’s input keeps switching, resetting your device to its factory defaults or enabling SIMPLINK may resolve the issue. If a hard reset isn’t possible, consider replacing the motherboard since it’s likely experiencing a malfunction. Or, contact an LG repairer for assistance. We’ll discuss common issues with HDMI inputs on LG televisions in this post. We’ll also explain how to perform a soft reset and restore your television to its factory default settings. If you’re replacing your TV’s motherboard at home, you’ll learn that here too! When your LG television powers on, it may default to HDMI regardless of the previous input you selected. There’s no way to alter the TV’s default HDMI connection at startup. However, the ideal approach is enabling SIMPLINK on the TV to resolve the issue. To activate this feature, follow these steps:
When SIMPLINK is active, it’ll show only the input of the powered-on connected device. LG TV HDMI Keeps Popping UpIf the HDMI indicator continues to appear on your LG TV screen, consider changing the HDMI cable you’re currently using. The length of an HDMI cable does impact signal strength, which may cause your television to malfunction. The majority of vendors don’t suggest using wires longer than 20 feet. Consider replacing the cable with one that covers the gap between the external device and the HDMI IN port on the television, but not longer. LG TV Keeps Showing HDMIIf your LG TV continues to show the HDMI ports linked to other devices, you can disable SIMPLINK to remove this notification. SIMPLINK, as previously stated, will remind you of all connected ports. As a result, disabling the setting would remove the HDMI alert. If this fails, try unplugging all devices connected through the HDMI port while the television is in operation. However, if none of the previous approaches work, you can post a message in the LG help thread. A technician will contact you and request your model number to resolve the issue. LG TV Keeps Saying New External Input Is ConnectedIf messages of a new input device continue to show on your LG TV, your connecting ports are likely dirty, causing the television to identify connections that aren’t there. Clean the input ports and the connecting wires’ ends. Before checking for improvements, connect the cables into the docks at least twice, too. If debris isn’t a problem, this often-occurring error code suggests a motherboard malfunction in your TV. Perform the following test to ensure that the motherboard is faulty before repairing it:

LG TV Keeps Asking To Change InputWhen another linked device powers on, it’s common for your LG television to prompt you to adjust the input. If you’d rather not see this prompt, disable SIMPLINK from the configuration menu. If this doesn’t fix the problem, consider changing the connected devices’ settings. For instance, if you’re connected to a device with an HDMI cable, you may want to disable the device’s HDMI control features. Likewise, review devices connected via AV or USB cables for a control function. The previous approach may not apply to all devices. Nonetheless, it’s a good idea to verify that this function isn’t active on the connected unit. If neither of the above solutions improves the situation, consider modifying the ports to which the gadgets are attached. The majority of LG television models come equipped with several HDMI, AV, and USB ports. Because every port may not cause this problem, it’s worthwhile to experiment with different cable setups.

The first procedure requires the entry of a password to access the input menu. To do this:
