White screen nokia n70

HI DEAR
FOR SIGNAL PROBLEM CHECK ATTENA IS CORRECT OR NOT IF NO THEN REPLACE IT AND IF YES THE RMOVE ATTENA SWITCH AND MAKE JUMPER ACCORDINGLY

REPROGRAM IS NEEDED!!

i got the same problem with my nokia 3110..i've just took out my memory card,sim card and battery and after 5 mins i kept battery inside and switched on then it worked,next with sim card and again with 3 of 'em..now the problem is solved

Don't put the battery / power on. Take the phone to the mechanic / nokia service center on urgent basis. They will remove the remnents of the water and salt over the circuit.
If the problem is still not solved, either the power supply or the motherbaord will require a replacement.

check your battery! i think you are using duplicate battery! put original battery to your mobile! again the problem came mean install new software and format your mobile

i also have the same problem...white screen display

for me the white screen you said, it might be your LCD.. maybe it losses connection to the main board..

a lot tobe done in that problem of your... but i can give you one of the best... place yur unit in table so you can be cmfortable...the press all the keys in same time these keys are key *,key3,the call,and power on switch... much better if you had buddy beside you..to hold the unit... press them in same time or together, dont release it until you dont see a word formatting... wait until it finsih and the unit will be restarted by itself... enjoy

it might be a software problem.try to run software update available on nokia site.if it does not work,you have a big problem,related to dropping a phone on a hard surface or similar...hardware repir needed in that case
