Hello friends, first sorry for my poor english.
I have a customers MSI CX61 0NE MS-16GB1 and someone did is badly heated with hot air station and N13P-GLR-A1 is become a short circuit. I am clean all flux on the board and reball the hm76 because i suspected solder balls get harmed. I am put 100% new gpu and notebook works but only intel 4000 shows in device manager, nvidia (gt635m) missing. I am suspect any smd parts (i am specially suspect gpu strap resistors) maybe missing or drop because hot air flow happen before . I am nothing find any hi res picture or schematic. Can anyone help me please ?Thanks.
