Why does my LG TV screen keep going black?
The LG TV screen going black issue can be caused by a variety of factors, including loose connections, faulty hardware, software glitches, or issues with the TV’s power supply. It’s also possible that the problem is related to the TV’s settings or the source device connected to it. To troubleshoot the issue, it’s essential to identify the root cause and take the necessary steps to resolve it.
Before attempting any troubleshooting steps, ensure that the TV is properly plugged in and that the power cord is securely connected to both the TV and the wall outlet.

How do I reset my LG TV to fix the black screen issue?
Resetting your LG TV can often resolve software-related issues, including the black screen problem. To reset your LG TV, press the ‘Settings’ button on your remote control, then navigate to ‘General’ or ‘System’ and select ‘Reset’ or ‘Reset to Initial Settings.’ Enter your TV’s PIN code, if prompted, and confirm that you want to reset the TV.
