Hi! My SJ7 worked fine. Used it on the motorcycle a few times. Now all of a sudden screen freezed. So i pulled out the battery. Then put the battery in again. Noting happens. Doesnt power up. Also attached on usb but doesnt do anything. Only thing i does is heat up so bad I cant toucht it. Seems its bricked. But there isnt any reason why this would happen. Didnt do anyting stupid with it. Is there anyone who recognizes this behauviour? Thanks in advance!
