My SG3 got dropped in water and LCD backlight doesn't work.

Hello,

I have a Samsung Galaxy SIII I9300 and I accidentally dropped it in water.

It was fully submerged for about 10 seconds. I took it out of water and removed battery to shut it down quickly.

I dried it outside then used my tool set to open/dissassembly the phone to dry internal water.

It was working fine for a few hours after being dried then LCD started to flicker and apparently got black.

Sometimes it flickers and then goes black again. I noticed the phone is fully working (everything but the LCD backlight, touchscreen still works). I can see the LCD still works because lines can be seen in a very dark place.

The LCD still produces a very low light (not totally black) that's why I'm sure the backlight is the problem. When looking into screen I can tell there are some stains (like water in the LCD).

I thought about running some high performance application to rise internal temperature thus drying it. If I do this the evaporated water can't go out because it is closed, right?

My question is: How can I internally dry the LCD?

I'm taking suggestions!

Thank you!
