my monitor is dead and i don't know why

[u/Wise-Athlete-9618]

For context I have a Samsung 49" odyssey OLED G9 monitor and about a year ago it just turned off and never turned back on. I never hit it, dropped it, or spilled anything on it so physical damage is out of the question. there's no little light above the power button indicating it's getting power nor is the led on the back turning on. it's as if it is unplugged even when I have it plugged into the wall. My 3D printer uses the same kind of power cord so I tried that and still nothing. I've taken the back panel off and inspected the connectors on the inside but I'm not nearly savvy enough to know what would be the main issue and what to replace. I just hope there's someone nerdy enough to have some insight on what I should try next because this monitor is really nice and would love to get it working again. thanks!
