Main Boards and Digital Boards - For Plasma TV's, LCD TV's & LED TV's


The board number will typically begin with the letters "EAX" followed by 8 digits. Sometimes, it might even have a parentheses with a random number inside it immediately after the 8th digit.

  • Example: EAX35618202(0)

The part number, on the other hand, can take one of 3 variations. It will usually begin with the letters "AGF," "EBR," or "EBT" followed by 8 digits and is usually found on a white-colored serial number sticker. 

In newer TV's, such as Plasma's, LED's, and LCD's made circa 2009 onward, the serial number sticker may be a different color. The most common ones are orange and green.

  • Example #1: AGF62350501
  • Example #2: EBR51295001
  • Example #3: EBT60683105

T-Con Boards - For LCD TV's & LED TV's


The board number will usually begin with the prefix "6870C-" followed by 4 digits and 1 letter and is commonly found stamped as white-colored text. Sometimes, it may be black-colored text.

  • Example: 6870C-0195A

The partial part number will usually be buried within the serial number that's stamped inside a white-colored box. It is commonly found stamped in red-colored text or black-colored text. In newer TV's, circa 2009 onward, sometimes the part number can be found on a serial number sticker in its complete form "6871L-####A." The prefix "6871L" isn't typically found on the board in most cases where there is no part number sticker. You would have to add that prefix to the partial part number buried within the serial number that is stamped on the board.

Other Miscellaneous Boards - For Plasma TV's, LCD TV's & LED TV's


For all other miscellaneous circuit boards, such as IR Sensors, Keypad Controllers, Wireless LAN, Bluetooth, and others not mentioned in the above will follow some such pattern of board numbers and part numbers as the above. Typically, most of them will have the board number that begins with the prefix "EAX" followed by 8 digits. And most will not have any kind of part number. You may treat the board number or model code (such as in cases with the Wireless LAN or Bluetooth) as if it was the part number for these miscellaneous circuit boards.
