[ask] 3500 key problem. - GSM-Forum

hello all.. i got this nokia 3500. when i turn it on, the down key is auto press. i already remove the side switch, and already change 2 keypad Ic, but still the same.
If i take off the battery for a longer time (like 1 day and more) the phone will be just fine, but later the down key is auto press again.

i wonder what's the problem? help please.. thanks.
