Now that you are familiar with the Arduino board and the procedure how to read/write from/to EEPROM, you should be skilled enough to do the A-board EEPROM reset.
In the next section I will show you how to locate the service connector on a Panasonic plasma, fabricate the service cable to connect to it, and do the reading of your TV’s EEPROM. Then finally, zero out the operation hours in the EEPROM to reset the black level back to the state when the TV was new.
