Hiya

Is that phone water damaged maybe???

I had same problem and i solved it by cleaning board with ultrasonic bath...

If that does not help check following line: switch - r402 - r221 - ccont...

Also check B200 32768 kHz osc and components around...

check line from key pay "3" to V414 to power switch !
or try to power off phone by short gnd to keypad 3 center connect , if it make phone off, then it is line cut from pin 3 via V414 to switch !
