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.

I do not have the remote control as it was an ex-showroom model.My son has managed to put the child lock on using the buttons on the side and I cant unlock it. Any Ideas


Sorry but this is impossible to answer accurately unless you tell the FixYa community exactly which make and model of TV you're referring to.

On many tv's the child lock involves setting a pin code and if this is forgotten the tv usually needs to opened up to be professionally reset. If you're lucky you may find that your son has activated a default pin code such as 0000, 1111 or similar, so try these first. Also try searching the web for a user manual as it may have the answer you need: normally they're free on manufacturer's websites or if they're not there then enter your exact model number followed by the word "instructions" into any search engine.

I've tried to be as helpful as I can given the need for guesswork and hope that when you rate my answer you take this into account. If you need further advice then please repost your question with the essential additional details.

Hi, I have a problem with my rca television model number RCAS01BA. My dauther has somehow put the child lock on without using the remote control as we had lost that a couple of months ago. (God bless...


You don't need the remote to unlock the TV. Any RCA universal remote will change channels etc if you want a remote.
Now from the manual: simultaneously hold down the menu/OK button and the Volume down button for 3 seconds. This resets the pasword and unlocks the TV. You can then enter the menus as usualI believe to control/clear parental settings etc.

HELP ME PLEASE.............


On your television, it has an initialization code. To get to this menu, press menu 2470. The menu will say "Initialize." Highlight this and press Enter. This will reset the TV back to factory settings. WARNING: This will also delete any user settings, e.g. color, channel settings, input labels, or other. After you press "Initialize" the TV will shut off and restart automatically. You should be unlocked at this point. Hope this helped.
