Chosen Solution

By mistake I left my tablet in washing machine. When cycle was finished, the screen will not boot, but I could hear that the tablet was OK since the sound was working, battery was working and when connected a USB, it sounded right. Screen is not damaged or cracked. I opened up the back and looked but don’t have knowledge to look for specific place for diagnosis. The back comes out easily, but there are screws to go further into other parts. I don’t know if screen needs to be replaced, or can be repaired. Thanks. Fred

@zooza before you can even start proper trouble shooting you will have to clean your tablet or risk it corroding away. You also should refrain from trying to charge, sysnc or turniong it on. This could make a bad situation worse. You will have to disassemble it and clean every part with a high grade isopropyl alcohol (90%+) otherwise it will definitely corrode. While you have it disassembled, replace the battery since it will fail for sure in a short while as well. Once you have everything cleaned, you can replace the LCD. Hopefully it is the LCD that has failed and not the mother board. Give us your tablets proper model number so we can try and find you some more specific information.
