Liquid damage, Screen is not lighting up

[imtmh]

My OP3 was kept in a bag (water resistant), during a heavy rain, I thought the phone is safe in that bag. But some water got leaked into the bag and the phone was kept in the bag for almost 1hour.
When I checked the phone after reaching home, it's got turned off(enough charge was there), I tried to turn it on, it did light up for a while and then turned off. I used a hair dryer to dry it and kept it in rice for 2 days. After that, it turned on normally, I tried to charge it. I got a call after few minutes of charging, spoke for a minute, but after the call the screen didn't light up. My phone is working fine except the screen. touch is working fine, I can unlock using the touch screen (It has a pattern lock), I can use google assistant to make calls, play music. But just that screen is not lighting up.
I am not sure what to do now, I think the issue is because of some short circuit. I don't think it's a right question to ask, can it be fixed without the whole screen replacement? (I think screen costs too much for my budget), also please share me if you have any links for buying the screen.
Thanks, everyone, have a nice day.

It's very likely that there is "only" some corrosion by the display connector because of the water. This probably causes the short circuit. If you can see some corrosion inside the phone (especially under the display connector) on the board, clean it carefully with a soft toothbrush and Isoprpyl alcohol (from the pharmacy).
Worked for me on my old Xperia.
Good luck!

Open up the phone and clean it out.. Might be some corrosion indeed. Watch JerryRigEverything, he explains it very well. I wonder, how much water came inside?

Yes mate, this is your only option, to open up the phone and check for rust. Be sure to dissconect the battery, and use coke in case you find any corrosion or rust. Googd luck
