Exclamation N70 Not switching on


I recently recieved a liquid damaged N70. I bathed and cleaned PCB. when i plug in the charger it switches on and shows its charging, but the phone will not switch on when I press the power button. I've checked the switch and the track to the RETU, I've changed the RETU but handset does still not switch on....

any ideas?
