FPA lock stands for Front Panel Access lock similar to Parental Control/Child lock - it indicates that the buttons on the front of the TV are locked so that it cannot be operated accidentally by young children.
You would need to use the remote to deactivate this security feature. Normally, you would go into the Parental Controls menu and turn off the FPA lock.
If for some reason a password was used, then you would have to enter that password since without it you can't get into the Parental Controls menu.
On some versions, you can press "Menu" on the front panel and "Vol -" on the remote simultaneously for 3 seconds to clear the password. in others, it would require that you press and hold at the same time the Vol < button on the front panel and CLEAR button of the remote control for about 5sec. You would need to enter a new password the next time you access the Parental Control Menu.
Usually, steps involve are explained better in the user's manual which is available at the RCA (Support) website
. You would need to enter the exact model number of your RCA TV.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
