Hello everybody, I have a problem with my macbook pro. I got it used and I have no idea what happened to it before. The screen did not work and after reading the forums here I decided to take it apart and find the fuse for LED backlight. I found it, and I just shorted the pins of the fuse and everything seemed to work just fine, however after 10 min the screen started flashing and then turned off. I have a video here: http://youtu.be/LKam1Zd0RRc start watching at about 2:30 I did reset the PRAM and SMC. External monitor works, and everything else in the computer works just fine. Where should I look and what could be worng?
