Finding the correct part number on Samsung Televisions. 

Lets start with the main audio video board, always look for the part number on the bar code sticker, this number starts with BN94-###### or BN96-###### as prefix for the main video boards, do not use the BN97 prefix since this is not a good number and can be found on numerous different boards.

Power supplies start with a prefix BN44-00####. 
T-con boards start with BN95-###### for most newer versions of televisions and older versions are as follows in this example: TX, UT-5550T12C09 in this case use this format when searching for a T-Con board 55.50T12.C09.
