Thanks, I'll look into it further but was hesitant in moving the light board. If it's easily adjustable then I won't be worried as much.
Interestingly, the original DMD had lines through it and filled the space. I had requested for the DMD to be changed and the seller (business) had assured me that the replacement DMD is the correct one. I do need to get them over once restrictions are eased to have a look at some other minor items so hope the tech can check it out again.
