The part number and revision must match. Shopjimmy.com repeats this advice is you need that.
I have a Samsung ME55C monitor whose main board has become damaged. I contacted Samsung who quoted me $286 for a new board. When I asked what the part number was, they wouldn't tell me, when I looked up my model number on samsungparts.com, there wasn't a listing for the main board. I have found a main board online that has the same ports and the same configuration but I can't get a part number to compare to other than what the parts sticker says, which samsung said was wrong. My question is: How can I find out if the new board is compatible? They come out of the same model monitor as far as I can tell but the part # is different, any thoughts would be appreciated.
