Sorry about your Monitor problems.
I have worked on several of these monitors and yours sounds like the BackLight has gone for a walk. ( NG ).
If you are experienced in the disassembly and the electronic component repair, let me know, and I will walk you thru the repair steps.

The backLight for your unit, can be ordered on EBay or direct from Samsung.
