This function will block out the picture and sound of the selected channel or video input.
It can also be used to keep the TV from being viewed for a scheduled time period that you set.
The code to enter the Locks feature is a four digit secret code number. The factory preset code is 0000.
Use the number buttons to select access code.

Use CURSOR G or H to highlight function and then press the SELECT button.
To change the access code number, select Change Access Code. Enter a new four digit key number you prefer.
Select CHANGE ACCESS CODE to change factory preset code (0000) to your preference.
When ENGAGE LOCK is selected, SET CHANNEL LOCK, SET INPUT LOCK, and SET FRONT PANEL LOCK can be set individually.
When SET CHANNEL LOCK is turned on, the picture and sound for the chosen channel will be blocked out.
When SET INPUT LOCK is turned on, the picture and sound for all video inputs and the picture and sound for channels 3, 4 will be
blocked out.
When FRONT PANEL LOCK is turned on, all buttons on the Front Panel will be deactivated, except the Power button.
When TV TIME LOCK is turned on (r TIME LOCK) you can set the BEGIN and END times (CURSOR E) and the TV
cannot be viewed during that time period (Set clock first). Use CURSOR G or H to highlight ONCE (TV will time out one time
only), DAILY (TV will time out every day), WEEKLY - SUN~WEEKLY - MON (TV will time out one time a week) or OFF (to disable
this function).
When MOVIE RATINGS is selected, you can block various types of movies and video tapes based on motion picture ratings. Picturein-
Picture will also be blocked automatically (see page 45).
When TV RATINGS is selected, various types of television programming based on a parental guide ratings will be blocked.
Picture-in-Picture will also be blocked automatically
If you forget your secret code, use the factory code 7777 to erase your key number. This will reset the secret code number back to the
factory preset 0000.
Press EXIT to quit the menu.

Hi,

As long as you remember the "CODE" The child lock on a TV is a wonderful thing.

The lock sometimes causes unwanted trouble--if it gets accidentally turned on and you don't know the code, you can find yourself unable to fully enjoy the full range of available television stations. Please apply the following possible 5 different solutions taht verified by different users and than hopefully you'll be back to watching regular TV ....


  1. Bring Up TV Menu ; Power on the television with the activated child lock on. Push the "Menu" button on the remote control. A series of features appears on the screen, ranging from the overall TV functions to the video display and the audio setup features ,Choose "Options" and a new menu appears on the screen. From the new menu select "Child Lock." The exact setup selection is going to vary slightly, although the child protection is always referred to as either "Child Lock" or "V-Chip." The V-chip is the actual chip built into the television that blocks out certain television programming.
  2. Try a "factory reset" action... This should be somewhere in the TV menu system. However Please note that will clear everything, so you may need to re-program every things..the channels etc.
  3. Hold the lock key in the remote for few seconds . you will get the lock tool bar . you can unlock it there
  4. Hold the display button on the remote for 10 seconds.
  5. As a The last solution which is common for all TV sets..
    • Try to find the User manual for your television. The section In the manual about how to set the child lock feature will also explain how to unlock it.
    • Try a few "universal methods" for unlocking the child lock. Some televisions have a universal code built in for disabling the child lock --no matter what your code is. A commonly used code is "0000."
    • Unplug your television for at least 1 hour . The internal memory battery of the TV is what helps remember what your code. When TV is unplugged for an extended period of time, it clears the internal memory, which in turn will reset your child lock code back to "0000 " again...
if the problem still continues you have to email to : http://www.akaiusa.com/

Hope this helps!
