Tablet doesn't turns on or charge. Overheating at the right sup corner
Everytime I attach the battery or plug the charger the tablet won't turn on but instead it overheats. The heat come from where the processor is and it get very hot. I used a multimeter to see if there are some power supplies issues and the battery looks fine with 3,7V. I already tried disconnect and reattach the battery but it still doesn't work, even tried to plug the charger without the batery and still the same.
I starting to guess that it might be a motherboard issue. Has anyone here experienced something similar?
Here's a photo from where the heat comes from:
