Tab 3 8.0 wont turn on!

[ben Fitzy]

Hi there, I am having a problem with my Tab 3 8.0. It will not charge or turn on, it's basically dead. I can confirm that the battery is not dead (i checked with a multimeter) its currently at 4.10V. I have tried all online methods (unplugging battery and plugging back in, button combinations, etc. and still no joy. I have also replaced the charging port so that's, not the problem either...



Any suggestions as to why I cannot get it to power on would be greatly appreciated!

Bad power switch? Dead motherboard? (4.2 Volts is almost "fresh off the charger".)

Welcome to Android Central! How long did you hold the Power button for? Press and hold it for at least 20 seconds and see if anything happens.

Old thread, but this worked for me. I put the Tab-3 in the freezer for 20mins. Took it out to thaw. Placed it on a wall charger that took 1-week to get the unit to respond. On another site, I discovered this device has a thermal sensor. To fool it and to charge a battery at ZERO power, it will do a slow charge. So slow, it took the 1-week to complete. Once done, it booted up right away.
