xperia z3 blank screen after trying to repair it after it got wet

Hello

so last summer i tryed to take pictures with my z3 under sea water. bad idea.

the phone showed an overheating alert and then shutdown.

after opening it and drying it the phone started again. i could hear everything, the vibrator works, the camera seemed to work everything seemed to work except the screen and degitizer that were blank.

in my attempt to repare it, i changed the screen, then the flex cable then both of them.

needless to say nothing changed still blank screen.

can you guys help me figure this out

unfortunately something may have blown or shorted on the logic board of the phone. if you can look very closely at the logic board and see if anything on there is out or wack or blown.

no, its the gpu, xperia 3 has a fragile gpu (i tried to change everything, but on xperia forums people complain about the gpu burning too easily) so you have to change the motherboard
