I was babysitting and somehow the kids managed to turn on the child lock, yet we haven't had a working remote for a long time, and they didn't even have the remote. Is there a way to turn on this function without the remote, and if so, how do I get it off? All I have is a black screen and it won't let me do anything!

I opened the TV, but no "switch" on the PCB to do a "reset to factory". ... You almost certainly need the remote, and also the service manual that .... and I was able to get into the menu by remote and to disable the Child lock.
Go to menu on your or set up on your remote control. then, look from the features that says child lock .Use the arrows to move to another feature. If the child lock is turned on, click turn off by using the arrows.
You can deactivate the buttons on the unit
(except for "/1) for preventing misoperation,
such as child mischief (child lock function).
When the child lock function is activated, the
buttons on the unit are locked and “ ” lights
up in the front panel display. (You can operate
the system by using the remote.)
•When you operate the buttons on the unit while the
child lock function is on, “CHILD LOCK” appears in
the front panel display.
1 Press SYSTEM MENU.
2 Press X/x repeatedly until “CHILD
LOCK” appears in the front panel
display, then press or c.
3 Press X/x to select a setting.
The default setting is underlined.
• “OFF”: Child lock function off.
• “ON”: Child lock function on.
4 Press .
The setting is made.
5 Press SYSTEM MENU.
The system menu turns off.
• You can activate the child lock function by pressing
x for more than 5 seconds (“ ” lights up in the
front panel display).
To cancel, press x for more than 5 seconds so that
“ ” disappears from the front panel display.
Deactivating the Buttons
on the Unit good luck
The power button on the TV doesn't work because of the child lock?
I went over the copy of your manual for your TV. It must be the child lock timer problem.
I would try leaving the TV unplugged for 30 mins and see if that reset the TV and releases the lock.
If it doesn't work, the remote needs to be replaced. A universal remotes aren't really universal when you need to use special buttons. The remote made for the TV is the best.
If your TV is the model 47PFL7403D, here's the cheapest place to buy a replacement. http://www.philips.newremotecontrol.com/catalog_item.php?catnum=313922852812

Parent Lock, or Child Lock, follow these steps:

Note: If you don't have a remote, you may
