How to Reset an Olevia TV
While many Olevia TVs have 1080p resolution, enhanced sound settings and a variety of ways for a user to adjust the picture, on occasion the television may fail to perform as expected. There may also be times when you want to start with a fresh slate and readjust all of the TV's settings. In these situations, you can reset the TV to get it to restore it to its factory settings.
Press the "Menu" button on the remote.
Use the up and down arrows on the remote to select "Settings," and press "Enter."
Use the arrows again to scroll to and highlight "Factory Default."
Press "Enter." At this point, the TV powers down and resets to its factory settings.
