Locate the manual for your television. Though slightly embarrassing, accidentally turning on the child lock to a TV is a common problem. 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 common code is "0000."

Unplug your television for a few minutes. The internal battery of the TV is what helps remember what your code. If the TV is unplugged for an extended period of time, it clears the internal memory, which in turn will reset your child lock code.
