Hello Looking at my father-in-Laws MacBook Pro unibody A1278 unibody. He accidently spilled cofee onto the keyboard. The computer seems to run just fine now 1 month later, however the backlit on the keyboard is gone and many keys on the keyboard are not working correctly. It is a 820-2936b board. On the mainboard a single capacitor is burned, can you help me to identify it please:
I managed to find this picture showing the capacitor in your guides, but cannot read the text:
Stokholm, that is reference designator C6603 and is a 100UF 20% 6.3V TANT capacitor. The case is a A L1 and something like this or on here should work. the capacitor is not part of your keyboard backlight, but of the Speaker Amp circuit. Hope this helps, good luck.
