Step 1: How to Enter the Serial Number:
When replacing the main board the new main board should have a blank serial number. However, if the new board came with a serial number already entered, this serial number is invalid and must be erased first and replaced with the one from the label on the back cover.
Turn on the TV and go to Settings > Support > About This TV. If a serial number exists, follow the instructions below to erase it and enter the serial number from the label on the back cover. If the serial number is blank, enter the serial number from the label on the back cover and complete the repair.
1. Take a picture of the serial number label on the back of TV.
2. Enter the Factory Menu by using a factory remote or a standard IR remote (Mute-182-Power).
3. Select SVC > S/N > Writing S/N.
4. When the soft keypad is displayed, select “Delete All” to erase the existing serial number if it’s not blank.
5. Use the soft keypad to enter the serial number from the label picture taken in Step #1. Please double check each digit to make sure all digits are entered correctly. You must enter all 15 digits.
