Hello! Thank you for reaching out! I get how losing the pin can be concerning. The default pin is 0000. But if you have changed it and forgot you can try the steps below to reset it.
Option 1. With a Samsung Smart Remote or Remote Control
Step 1. Turn on the TV, then press the Volume button.
Step 2. Press the + button to increase the volume, then press the Return button.
Step 3. Press the – button to decrease the volume, then press the Return button.
Step 4. Press the + button again, then press the Return button, and the PIN should be reset to 0000.
Option 2. With a standard Remote Control
Step 1. Turn on the TV, then press the Mute button.
Step 2. Press the + button, then press the Return button.
Step 3. Press the - button, then press the Return button.
Step 4. Press the + button again, then press the Return button, and the PIN should be reset to 0000.
Your TV’s default PIN should be set to 0000 once again.
If this doesn't help I would recommend you contact your place of purchase if you got the display model as they should have the pin. Or setup up an exchange if possible.
