Hat geantwortet auf: Why won't my tablet turn on?I am very annoyed w/Samsung. I have (2) Note 8 tablets which I paid $300USD for each. Within months of each other the screen went black on both devices. I changed the battery and USB port with no success. I called Samsung and was told it could be the motherboard, they wanted a 300deposit for each device and said it would cost 190usd to fix each one. A search for motherboards indicates they can range from 50usd for a used one to 104usd for an OEM. I don't think I am going to put forth the effort to fix either device at those cost.
