Chosen Solution
Hello, so ive made a mistake on my mid 2010 macbook pro intel core duo 2.66Ghz . During a cleaning session for multiple of the laptops i work on and refurbish. I failed to realize that the battery was still plugged in to my macbook, while unplugging a display ribbon cable, the device turned on. I immediately shut it off and put it back together and noticed the LCD backlight is now nonfunctional. I have attached a picture of the only burnt component i could locate. [edited to show the location for the backlight fuse/circuit, and a more complete board view]
Is this just a 0 ohm resistor/jumper that can be replaced with a drop of solder/wire? It seems to be unmarked like the resistors around it. I have experience with microsolderong but this is a bit out of my knowledge range as to what it is.
@mike2021 not it is not. The component in question is: reference designator L3404 which is a 120 Ohm 1.5A Ferrite inductor in a 0402 package right next to it is reference designator C3422 which is a 0.1uF 10V 20% capacitor in a 0402 package You do not want to apply any jumpers to this but replace them. Both parts are available at places like digikey.com or Mouser.com as well as many other places.
