Most RCA and GE TV sets use a four digit code to control the v-chip. The code reset is different depending on the model. Try each number until you find the one that works for you.

1. Hold down the MENU button on the remote and VOLUME DOWN button on the TV it’s self at the same time for at least 4 seconds. The set won't say so, but the lock will be unlocked
2. Hold down the 0 (zero) button on the remote and the VOLUME DOWN button on the TV itself at the same time for at least 4 seconds. The set won't say so, but the lock will be unlocked
3. Hold down the MENU button on the front of the TV and the TV button on the remote at the same time for at least 4 seconds. 4- Hold down GO BACK button on the remote and MENU button on the front of the TV at the same time for at least 4 seconds.
4. Hold down EJECT button on the front of the TV set and the MENU button on the remote at the same time for at least 4 seconds. Depending on the model, one of the methods should unlock the V-chip. Now, if desired, you can change the settings on the V-chip by going to the MENU and going to PARENTAL CONTROLS, or on some sets, going to MENU and then going to TV SETUP, then to V-CHIP SET.

If you forget your password you can reset it. Make sure the
TV is off. Simultaneously press and hold VOL< on the TV’s front
panel and CLEAR on the remote for approximately 5 seconds. Enter
a new password next time you access the PARENTAL CONTROL
menu.
