Generally, LG Smart TVs are great devices, but they can sometimes run into problems. 

Unlike its laptop or computer counterpart, your Smart TV's memory and resources are far more limited. 

Consequently, with streaming services like Netflix, Hulu, and Pandora, it is easy to exhaust them quickly. 

This leads to a common problem which is the "Out of Memory" error. 

Basically, this error occurs when the TV's internal memory is full.

This will erase all of your settings and data, so make sure to back up anything important before you do it.

To perform a factory reset, follow these steps:

• Press the Settings button on your remote.
• Select General.
• Select Reset.
• Select Reset to factory settings.
• Select Yes to confirm.

3. Use a USB drive for additional storage

If you need more storage space for your LG Smart TV, you can use a USB drive. 

To do this, follow these steps:

• Connect a USB drive to one of the TV's USB ports.
• On the TV's home screen, select Settings.
• Select General.
• Select Storage.
• Select the USB drive.
• Select Use as external storage.

Once you've done this, you can move files from the TV's internal memory to the USB drive. This will free up space on the TV's internal memory and prevent the "Out of Memory" error from occurring.
