My phone get wet and screen black

@edom you are not telling us what you did after your phone got wet. I assume that you didn't clean it etc.

For now, you must stop continuing to try to charge, sync or otherwise use your phone. This potentially can make a bad situation worse. This may further damage your phone.

The very first step I would take is to disassemble your phone. Since ifixit does not yet have a guide for this phone, use something like this video to help you disassemble your phone. Remove the main board and the charging board. You will have to remove all the EMI shields. If you do not remove the shields, you are not cleaning the board.

Take a close look at all components and connectors. Look for major corrosion, evaluate the pins in the connectors etc,. Take a look at all connectors as well as cable ends. .

It was written for an Apple iPhone 3G but all the steps are still pertinent to your phone as well. I can not stress the importance of a good cleaning enough, so do it over and over while replacing the alcohol after each cleaning.

After that, reassemble your phone and re-evaluate. For as long as you have not cleaned your board and replaced the battery, everything is just a guess. Keep in mind that water damage is the hardest to troubleshoot and to repair. It does not matter if is was exposed for 2 seconds or 2 hours, what matters is where the water (particulates) did the damage.

In your specific case, pay particular attention to the LCD connector and LCD cable.

It is possible that this is a board related issue. for that you will have to look at the schematic and probe the proper points to determine which part may have failed. To point the parts out to you, we will need to have you post some good, clear and large pictures of your circuit board (both sides) with your Question 기존 질문에 이미지 추가하기
