Unlock parental control

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.

That model does not have a V-Chip, so that is not possible.

Please remember to rate my solution. :)

From the user manual p65.
Lost password ? In the password screen (see page 54), enter the following master password: 4357. The master password clears your previous password; it cannot be used to temporarily unblock channels.

Under the main menu, go to the Parent tab and enter the Master Password: 4357. This will completely clear the present password. You can enter a new one afterward.

Ask your parents for the owners manual, it's in there, probably page 97.

ya i had the same problem and after a long while looking i found the master code for it was 4357 so good luck

You can try to enter the following master password: 4357. After using the master password, you must create a new password. The master
password cannot be used to unlock currently blocked channels.
Good Luck.

Try 8888

You can try these codes 2211 or 3308 if they do not work you will need to reset the unit. You will need to unplug it for 45 minutes that will reset the TV to factory settings. Then the pass codes I provided should work.

When there is a parental code, you have to ring up your tv service provider for the code.
