You cannot change just the DMD chip, you will need to replace the DMD board.
The board is not going to be rocket science to change but its not a walk in the park either.
It basically consists of taking the set apart, finding the dmd board which is going to be almost right in front of you, unplugging some delicate wires, taking out the screws holding the dmd in place, taking it out and putting the new one back in. One of the hardest parts is after you replace it you will need to align the new board. This takes two people to make it easy, one is in the back moving the board around until the one in the front says its good. This is also the most dangerous part because your hands are in the set while it is on, one wrong move and you will get hurt or destroy your new board or worse your set.
The part number you need depends on the serial number, if you give me the serial number off the back I can do some research and get back to you in a few hours with a part number. Both boards that it could be are around $200.
Please let me know if you have more questions or would like more information.
If you would like any additional information or have more questions please don't hesitate to ask!
I am sorry now we need the date of manufacture off the back.
Looks like they had some problems with this part so they changed it a few times so its hard to look up what one you need. If you can get me the date I can tell you the part number you need.
The part number for your DMD module according to samsung is BP96-01636a
Please let me know if there is anything else I can do for you!

I have never seen a DMD board come without the chip, on all the DMD boards that I have replaced over the years. Yes the DMD chip is the problem but I have also never seen just the DMD chip sold before. I am going to look into this for you and see why you got a board without a chip, this is something new that I have not seen. I even changed a board last week in a different model than yours and the chip was in it. I am blown away that you got a board without one.
Did you order the part number I gave you?
Where did you order it from?
Let me know so I can check into this for you.
Well this looks like the first time I have encountered this, but the DMD chip is sold separately on this model for whatever reason. There are two different ones however so we need the version code of the tv. Can you look on the back and see if it is version code PB01 or PB02 so I can give you the correct part number.
The part number you need directly from Samsung's parts research department is 4719-001981
