Anonymous users2024-01-22You should leave the phone dry for a few more days after it is turned on. I have a mobile phone, after falling into the water, I blow dry, I left it for three days, and it still works. I used to have a mobile phone that fell into the water, and after that, it could be turned on after a few days, but it couldn't be turned on after a few days.
Later, it was repaired. It's repaired, but it's often broken, so it's not needed.

It is estimated that it was burned, you didn't take it apart and dry it, let it dry for a few days, and the picture was displayed because it was still a little, and it was dark because the line burned after the power was turned on.
Generally don't be too anxious like this, after drying, wait for two days to dry, then fully charge, and then turn on the machine to try. It is best to take off the electric board during shutdown, and the all-in-one can also be disassembled and separated with a screwdriver.
It's not easy to repair it, it's a waste of money, it's better to buy a new machine as soon as possible.
