phone boots up but screen doesn't work, water damaged, badly dryed up
One year ago a friend gave me a water damaged huawei p10 to fix, he said that it had fallen in water and he used rice to try drying up the phone. since then, every time he was trying to turn it on, it was just getting hotter and hotter, and the result was just a black screen and a little furnace, no feedbacks. I seem to recall that the phone didn’t used to get hot while charging, but only while he was trying to turn on, i mean the boot phase (?).
I cleaned up the phone with iso and trichloroethylene (DON’T USE WITHOUT PROPER VENTILATION) and i tried to resolder every chip on the board. now it works, i mean, it turns on but the screen is completely black, i can ear notifications and everything, I can also see the notification light, the vibration works, but the screen stays back :(
what to do ?
I’m not able to read the schematics ( I can’t find some that are at least easy to understand and trust ) but I’m good at soldering so if it’s a chip don’t say it’s impossible to replace :)
Questa è una buona domanda?
