ok I tried the dimming and I got nothing. I even pause 500 at the beginning of initialization for the lcd and nothing. The funny part is that now on this 4x20 lcd screen only two lines light. the second and the fourth. What really am I to see when this thing really kicks off.

the program that is attached is the last program that I am actualling trying to get to work. It worked before for someone else why not me right. Tried it and got nothing.

could the crystal play a role to the problem

I got this to ask. When I write pause 15 does that mean I pause 15mS for a 4MHz crystal. What is the time constant for the 4MHz crystal. isn't it .25us. so that leave the program and the chip to produce a 15ms pause time.

I am trying to figure out my problem and all that I am possed with is a timing issue. Why I bring this up is that even my LCD sample program does not work with the setup that I am running. I have attached the program(s) that I use as the sample.
