Your delay loop might be optimized away, causing your output ports to be
high most of the time. Try making i, j, and k volatile (maybe a volatile
k suffices) or insert an _asm nop _endasm; (or even an empty _asm
_endasm;) into the inner loop body.

You might want to move the line "TRISD = 0x00;" out of the loop (should
not solve the problem, though ;-) ).
