Answer

고나서 ....its like after doing something ...you did something else

I watched TV after homework 
나는 숙제를 하고나서 텔레비전을 봤어요

자마자 .... an action which is performed immediately with prefixed action or activity

I slept immediately after going home
집에 가자마자 잤어요

Answer

1번은 TV를 다 보았고, 2번은 TV를 거의 보지 못했다는 의미입니다.

1. After I finished watching TV, I slept (I watched TV)
2. As soon as I watched TV, I slept (I was not watched TV)

As soon as I finished watching TV, I slept 는
'텔레비전을 다 보자마자 잤어요.' 라고 하면 됩니다.

Answer

In fact, the second sentence "텔레비전을 보자마자 잤어요" sounds like when your sight reached tv, you slept right away simultaneously.
