If the screen on your LG TV looks dark or dim, it is usually because [Energy Saving] is turned on or [Picture Mode] is not set correctly.
Use the remote to set [Energy Saving Step] to [Off], then change [Picture Mode] to [Standard] to resolve this.
If changing these settings does not resolve the issue, try resetting the picture settings.
[Picture Mode] is set to [Eco] or [Auto Power Save].
[Energy Saving Step] is set to [Auto] or [Maximum].
The HDMI cable or antenna connection is loose.
There may be an issue with the TV itself.
On your TV remote, press the [Settings] (gear icon) or [Mute] button three times in a row.
