That star screw head is actually called a Torx security screw, the pin in the middle is what makes it a security screw. A mating Torx bit or driver of the appropriate size. You can buy a set of them or a combination set with standard from GearBest from the UK. They are fairly common in the U.S. In Dollars, they cost around 8.00-20.00. eBay is a good source, also. Thank you for enlightening me on what to look for and expect. My 15-year-old Panasonic has been flawless, until tonight.
