I have an Asus Zenfone 2 phone, I stopped using it a long time ago, probably because I fell and stopped working, and I do not know if the motherboard or processor has fallen, the display does not light up even if I connect it to the charger. I have a tool to repair this type of processor but I don't know if it's worth the risk, what else can I check what works and what doesn't. Maybe the fault lies in something else, but rather not in the battery because it was replaced and it did not work. On the website they told me that it might be a processor but they are not sure. I would be grateful for help.
