Hi sifus...need help here...the greyed key not functioning...i've posted here before regarding this.



some sifus said that i need to desolder and resolder back as well as use multimeter to check diode...i did those and the key still not functioning. diodes are ok...then i saw mold like thingy on the pcb area



that are adjoining to the microcontroller/ic



not sure its related to my problems or not...but i cant find anything else that might cause the keyboard to broke. is it possible to fix it? or need to get new pcb board/mkb?
