Chosen Solution
Hello, Since my Samsung Galaxy A40 wasn’t charging anymore I replaced the battery first (without any change) and then the charger connector, but still not charging. I definitely don’t know why and how it’s possible, any idea? Thank you for your help, Fabrizio
don’t worry, when you said you had a usb voltmeter I thought you were a technician or repairer …. usually this type of equipment is not in the possession of “non-industry” people … I have attached photos of the jumper from run to solve the charging problem
check if you see the varistor component is burnt…try to change it Aggiorna (01/05/2020)
