The down arrow does’t work by itself. no water damage but if i press shift and down arrow it will scroll down also if i press command and down arrow it will also scroll down but if i press the down arrow by itself it wont do anything. what have i done so far cleaned the weird silicone dome inside the key with isopropyl alcoholfactory reset the keyboardlet it discharge and recharge it nothing helped so far anyone else had encountered this error? Thanks in advance UPDATE: I include a picture of the issue
The switches contact blister has failed. The keyboard is not really repairable. Update (03/29/2019) Yes, this can be confusing! Why does pressing two keys make it work! This gets into the mechanics on how a keyboard works. Simply put, its like a spreadsheet a group of columns and rows, in this case the down key has failed so when the neighboring key (electrically) is also pressed the signal gets driven to the decoder logic within the keyboard and it accepts it as the key you wanted. Often times a liquid spill is the cause of this type of problem.
