I've had my Onkyo TX-NR 686 for less than 2 years, hooked up to 2 warfdale bookshelves, a Klipshe center channel, Nintendo Switch, PS4 Pro, roku and 4k player. Out of nowhere my display goes out. TV display is fine. I directly plugged all products to TV (Hisense) and they work. I did a soft reset, no luck, did a hard reset and nothing. how can I get my display to show again.....or is it paperweight now????? Please help!!!!
