To troubleshoot your LG TV model `42L V4400`, start by ensuring that you’re trying to change the input correctly. Use both the remote and the side panel buttons. If the remote is functioning well, check the batteries to confirm they’re fresh.
If you’re still facing issues, try turning off the TV and unplugging it from the power source for about a minute. Make sure to disconnect any HDMI cables connected to the TV during this time. After a minute, plug the TV back in and turn it on. Then, attempt to change the input again using both the remote and the side panel buttons.
If the screen remains blank and the inputs still don’t register, it’s likely that the problem is hardware-related. Since you’ve already tried the basic troubleshooting steps without success, the best course of action would be to have a technician examine the TV. Given that you purchased the TV recently, you should be able to utilize the warranty for repairs. You can schedule a service by contacting LG support or, if you have an extended warranty, reach out to the appropriate service number for assistance.
