Try it this way.

Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to the keypad and key in any 4 digit code you like and press enter.

Try pressing the 'set code' or 'code' button and keep pressing it until the light indicator lights. Press tv and after that you are suppose to enter the 3 or 4 digit code and press enter. However, if you don't know the code, try to repeatedly press the power on button of the remote until you get a response from the tv set. sometimes it would take a hundred times or more before you can get a response. Once you get a response, press enter. I have tried it many times in universal remote controls and it works.

There are a few different "default" codes that you can try.

0000 or 1111 or 1234 or 9876 etc.

Here is something that i just came across, I do not know if it will work but it maybe worth a try:

5. Use the Down Arrow to highlight the PARENTAL CC then press ENTER. Now type the Parental Control setting you want with the remote (8 is the highest setting, press 8 on the remote for a fully unlocked player). Then press ENTER on the remote after entering your new setting.
6. Use the Down Arrow to highlight the PARENTAL PW. If you wnat to change this, press ENTER. You can enter any 4-digit code here. Press ENTER on the remote after you enter the 4-digit code.
7. To exit the menu and save your settings and push OPEN/CLOSE with the remote.
