Samsung 793DF problem

[parimal]

I recently bought Samsung Syncmaster 793DF monitor for myself. But right from the first day horizontal brown lines are coming on the screen. These lines comes and go in a second. This is happening once in a hour. What could be the problem?? I called a serviceman from Samsung, he done something but still I'm facing the problem. Anyboady is facing the same problem..??
