I would say 'yes' to that; TRISD=0 makes all pins Outputs (all 1's would make them Inputs; 0=O; 1=I). Another problem in your code: delay() takes an (unsigned) char argument, but you pass in 1000, which is truncated to 1000 % 256 = 232. What *do* you see: LED full bright on, LED completely dark, LED half bright on? What compiler/linker options do you use?
