Why is the 3rd diagnostic led on with external monitor?

crwdns2934249:0crwdne2934249:0:

I have changed the logic board as the lcd connector was damaged. I have put all the parts back and only two led lights are on and the screen is black. When I connect the external monitor  third diagnostic led goes on but there is no image on the external monitor. I. cannot figure out what is wrong. Anybody had similar issues?

Thanks a mil for help
