I have a Sony a6000 love it and carry it with me all the time , but now it has become very temperamental sometimes works other times none of the controls work, f stop , iso ,nor can I operate the menu . I’ve tried taking in and out the battery , cleaning the contacts and resetting . Think it’s ok then no it stops! Has anyone had this happen, is there anything else I could try or is it a trip to repair shop ..or even time to upgrade?
