I have a 15-year-old Toshiba Satellite L675D-S7015, the computer boots for 5 seconds but, then does nothing. The computer and screen Rarely boot completely. Does anybody know what’s going on? Update (10/23/2020) Ok guys, I was able to turn it on again, but the USB port don’t work at all, and they’re like brand new

@therealstarr16 connect an external monitor. If that shows up okay etc. you know that it is your LCD screen that has failed. Let us know what you find out.
