So this 6 is my classmates, she said the screen was broken. Tried a new one, still not turning on. Tried a new battery, charge port and screen. Still dead. How could I test the Tristar without removing it?

Is this a good question?

Depending on the series of 6’s I suggest very strongly go after the TIGRIS first because he is the one that controls the battery with a MOSFET
