what did I do to my Oppo/Modwright UDP-205 ?


Like a real fool I unplugged my new umbilical cord I just got from wywires because I was hearing static (I thought it was the new cord) and then plugged it back in with the power supply still on! a few seconds later a loud pop and what looked like a flash, the Oppo still played so I thought I was safe but NO! now I am getting the same pop as the music plays what did I do?

I must admit I was getting a volume drop at times of the loud pop, I praying I didn't fry something, the thing is I know better than to do stupid stuff like this
