Chosen Solution
so i bought a mac book pro from family because it was not working and i wanted to see if i can fix it, this is my first computer fix but i think that i can do it with a little intell. so i got a charger can charge did up and did a Shift+Control+Option+Power reboot i can heard the logo sound but it was still black so i got a strong flash light and i saw the icons for the account. i think it is a fuse on the logic board. but i am not really sure. well i am stuck any ideas i am 15 and sorta new to this stuff
I would first inspect things as often times the display connector on the logic board gets wet when shorts out and/or has corrosion. Follow this guide MacBook Pro 15" Unibody Mid 2010 Display Replacement Follow it to Step 6 then jump to Step 15 carefully sliding out the cable connector and then check the connections both cable and logic board
Use a soft tooth brush or cotton swab (Q-Tip) and 70% or better isopropyl alcohol to wipe down the surfaces. You may need a fresh pink pencil eraser to remove any tarnish on the cable connector surface. Beyond that you will need to find someone with the deeper skills to micro-solder and has the needed tools as well as access to the parts to fix your system. For now you can still use your system by plugging in an external monitor.
