K4000 Missing a Chip?

Hi, I purchased a second hand K4000. Opened it up to clean it form dust and found a nasty surprise:



Looks like one of the chips is missing!

Can anyone confirm that this isn’t normal? Should I return it?

EDIT: Well, it works with the DVI cable, but if I plug in DP1.2 in either slot… nothing. Is there something I don’t know about this? Or is this the result of the missing chip?
