Xperia z: water damaged..
 

HEY guys i have a big problem and trying to figure out how to fix it,This is waterproof phone but it seems like water went inside the phone i used a hairdryer to clean it but that doesnt seems to work,so the phone wont turn on its dead,when i connected it to charger it shows red light and after 3 seconds it vibrates 3 times and then restarts and again,i can get the phone only into fastboot mode,anything else is useless tried almost everything,Any suggestions?

Test with a second battery or follow water trace to find shorted capacitor or cuted fuse

Is it possible to take off the screen without breaking it?

Yes but whay you try to pool out the lcd

i somehow turned it on,it it showed sony logo and turned on but after 1 minute it turned down and i cant turn it on again when i plug it in to a pc it shows that is charging but it wont turn on now i think that water made some damage inside i will try to clean it with a hair dryer..

Search in the motherboard any water or clor risidu (white green color) and clean it
