So I successfully removed my laser from a DVD burner (its a Sony DRU-800A) and I don't know how to get it to work. I tried just leaving the ribbon cable on the diode and sticking a needle through each wire (theres a positive and negative no ground) and connecting it to 2 AA batteries but nothing happened. I hope I didn't mess anything up but I just wanted to know whats the safest way to get this working. Would a resistor be a must? What I did probably didn't work and I hope nothing bad happened because of it. Thanks
