  Sarah TaylorAug 6, 2025
  If your LG LED TV shows no picture, first, ensure the TV is turned ON. Check if the antenna or cable is properly connected to the TV. Verify all connections to the TV are correct. If applicable, ensure the MPI cable is connected to the MPI device. If you're on an encrypted program, try switching to another channel. Finally, check and adjust the Installer Menu settings if the tuning band is incorrect.

Why doesn't my LG 40LX570H LED TV remote work?
- B
  Brian ThorntonAug 12, 2025
  If your LG LED TV remote isn't working, first ensure it's in 'TV' mode using the MODE key. Point the remote directly at the IR receiver on the TV, and make sure you're close enough with no obstructions in the path. If applicable, check that the MPI cable is connected to the MPI device. Replace the batteries, ensuring they are correctly oriented. Dim the room light, as too much light can interfere. If none of these steps work, you may need a compatible LG Installer Remote; contact your LG representative.

  If your LG LED TV has a normal picture but poor or no sound, first, check if the audio is muted. Press the MUTE button or use the Volume Up key to increase the sound level. If that doesn't work, the issue might be with the broadcast itself, so try changing to a different channel.

How to fix LG LED TV when I cannot directly enter a channel number?
- A
  Amy McfarlandAug 30, 2025
  If you cannot directly enter a channel number on your LG LED TV, it could be because the TV is in Pass-through Mode and Installer Menu item 028 CH. OVERIDE is set to 0 (disabled). To fix this, set CH. OVERIDE to 1 to allow direct keypad entry. Alternatively, if the TV is in FTG Mode, the channel might not be included in the FTG Channel Map. In that case, modify the FTG Channel Map using the FTG File Manager or the FTG Device Configuration Application.
