Oooo.. I know what you mean! I did the same thing! I searched for videos on how to fix my machine, watched the videos over and over again to build my courage to open it up and when I finally did, I prayed I don't destroy it hahah. There was once, my fixing didn't work after I opened it apart, only to find out later at the repair shop that I turned on the wrong button :P
Such a wonderful sharing, thank you dear <3
