Screen wont work right

Coltspm — Fri, 17 Jun 2016 22:39:25 GMT

I got a bit of water on my sony Xperia z3v. The phone was dead when this happened. I immediately put it in rice and let it sit there for a few days. The i removed the back glass panel because it was cracked and i was going to replace it. Then i turned it on to see if it worked without the back panel. It didnt turn on due to it being dead so i charged it. Once it was charged i turned it on and the screen wouldn't respond to my touches. Then it started acting up and selecting things on its own in a very rapid way. What i wanted to know is how to fix this problem. Is it because the back panel is not on? Please help me because i am a big fan of these phones.

@Coltspm

Hard to tell, the problem could be due to water damage or it could be because of impact.

That's the water damage in your phone. You're going to have to say rest in peace, OR, get a blow dryer and blow dry into the phone and the heat will evaporate the water, you have to hold it there for 10min or so. Put it back in the rice after you thnk you have evaporated the water. If it still does not work, i would advise you to take apart the phone (if you know what you are doing)

You should take the battery out for this.

That's a terrible idea, @Coltspm keep the phone away from heat

Don't listen to @uliwooly

You already voided your warranty by taking the back off.

Use a hairdryer and fry your phone. I dare you

Your suggestion WILL DAMAGE the phone, that's not ok.

Thats water damage. Back glass has nothing to do with the touch screen , Only NFC.

First try dong a Software repair with the xperia Companion if it wont work do this :

Since it was in rice and the screen is not working try doing this :

Since your Back is already removed

Turn off your phone.

There will be 5 Flex cables on the phone motherboard 1- Camera (Top left corner) 2- Top microhpone & 3.5MM jack (top right corner)

3- Battery Connector (Its placed right over another connector so they're very close) 4 - under the battery connector i think its to the Magnetic charging port. 5- Screen , Buttons , buttom speacker connector its the widest connector on the motherboard

Unclip the 5th Connector ( The widest) and 3rd Connector ( battery connector) wait a minute , connect them again and turn on your phone.

If it wont work follow all these steps to dissassemble your phone : https://www.youtube.com/watch?v=9ZLLChEXzWk

You dont have to remove the screen. Just clean the connectors with a 100% alcohol cloth and put it back in rice for a few days.
