Your Apex TV has been locked by anyway. Just try this method to unlock it.
Apex TVs have parental locks that allow you to block certain programs based on
their rating. When this feature is no longer needed and you want your TV to display all programming no matter its rating, you must unlock your TV. Unlocking your Apex TV is done completely from your remote control and does not require any tools. The process takes less than 5 minutes.
• Press the "Menu" button on the remote control and use the arrow buttons to scroll down to the "Parental Guide" option, then press the "Enter" button.
Type in the default parental code "6688" if you have not set your own code. If you have set your own code, type it in. If you set your own code and forgot it, override it by using "6688."
Use the arrow keys to switch the parental lock to "OFF." This allows all programs to be viewed no matter the rating. Press the "Exit" button on the remote and start watching all your channels.
