Samsung TV won't turn on, no stand by light

My TV, bought in 2020, worked just fine last night but now will not turn on this morning. I have tried trouble shooting it, switching it from a power strip to a direct outlet, and still nothing. A quick google search made it seems like the power supply board went bad. Would someone be able to confirm that this is the likely problem? Also I am unsure of what model of power supply board I would need.

Model code: UNTU700DFXZA

Version No: FA01/UTU700D/UTU7000K-U65TK1

S/N: 09MZ3CSN500843T

Thanks for any and all help
