Why is my lg g3 phone not powering on?
My lg g3 showed blue or black screen when I opened it and heated the black chip inside the phone now the phone is completely dead it wouldn't power on again
A large smartphone by LG, released in fall 2014. The LG G3 (D855) boasts a Quad HD IPS display and a 13-megapixel camera.
when you say heated the black chip, what did you use to heat it? used flux to reflow and put kapton tape (or a similar heat resistant tape) over other board components?
if you just took a heat gun and heated the board for X amount of seconds you likely burned some board components
