Not to make you feel bad for what you've already tried, but I think "crying it out" can just make things worse because he just wonders why you won't come save him (from being scared or upset or whatever is wrong) when usually you are there for him whenever he needs you. And then if you eventually give in and take him to your bed or lay with him, that just teaches him that he needs to keep on crying until he finds your breaking point, which may mean to cry for an hour or more, because he's figured out that you will eventually come in. Here is what I have done (I have 3 kids)...
Do whatever your night-night routine is (though I would skip the TV at bedtime because studies show it stimulates the brain and hinders restful sleep - basically it makes it harder for his active brain cells to settle down and rest)... Then don't say goodnight as if you are leaving. Sit with him for a VERY brief time (seriously like one minute- long enough to maybe sing one song to him) and then say, "I'll be right back. I have to go do___" and fill in the blank with something boring like laundry or wash the dishes. Then leave his room, reminding him that you will be right back. Make sure you say what you mean and mean what you say-- go back into his room after only a few minutes (maybe 10-15 minutes if he is quiet, or go in after just a few minutes if he is crying). Let him know you are checking in on him to make sure he is OK, give him a hug or a pat, and make another excuse why you have to leave to do something boring and tell him you'll be right back. Keep doing this and make the length of time you are gone longer and longer until he is alseep when you walk in. That way, he eventually fell asleep on his own, and you did actually have an opportunity to leave the room to get things done, including tending to your baby.
I have not only done this with my own kids, but I have recommended it here before and moms have written to thank me and let me know it worked well. You should have to do it less and less each night as your child regains the confidence to go it alone.
