Default TCL 75R615 has sound, no backlight

Have had this TV since June 2019, worked fine till today. Daughter was watching it and made a noise and went dark. I unplugged, left off then powered back on, no change. You can see the image with flashlight test, but has high pitched noise/whine and no backlight whatsoever......I also tried a factory reset with the reset button on the back. Any ideas where I should start troubleshooting? Im pretty good with soldering iron and multimeter, but I dont have any documentation on this TV so I dont know where to start.
