I thought i posted my reply, but maybe not.
It depends on what model LCD you have.
I went through this problem with Samsung tech support.
I have 460FP-2 and timer2, 3 and holiday are greyed out, no way at all to get to them.
Since researching this, we ordered another LCD , but model 460FP-3.
This new model can access timer2 , 3 and holidays.
I am running version 3101/2600 on both LCD's.
you would have thought it was a software issue instead of a LCD model# issue.
