Hello I just changed the broken monitor from an Macbook pro 2012 to a 2011 changing che lcd cable, everything went good but when i mounted all together the light charger at beginnig was smooth green light and after a couple of minutes sign off. I examined my logic board and found that a capacitor blown off here are the picture:

It’s possible to buy it online and change it? Is this the problem? Thanks

marcinjak9 that is not a capacitor. That is reference designator L6995 which is a 33UH-20%-0.44A-0.455OHM inductor in a D52LC-SM package. It is a critical part of your “G3Hot” supply circuitry for the DC-in and battery connection. For replacement you want to check places like this and here as well. The replacement part will have to be properly soldered to make it work.
