[MegaBassX]

hi,
i looking for replace my main board from my panasonic tc-l55et5x (manufactured in mexico) i cant find in my country this board, i attach the picture of my board, and i notice that my board is a TNPH1006 (1) [A], but that i found in ebay says TNPH1006(2)[A] for TC-L555ET5, and that says TNPH1006 (1) [A] is from TC-L47ET5


so i found in ebay the main board for a tc-l55et5 (note it dont have the X in the model) that it have the part number: TXN/A1SJUUS (TNPH1006UM) abut the $123.20

but i found a main board from a tc-l47et5 with part number
TNPH1006UC-TXN-A1SKUUS-TC-L47ET5

witch main board i will buy? i think the TC-L555ET5

in the link for download the firmware says all ET5 and ET5X (inclusive E50) models use the same firmware
