Question Help!! Asus ROG swift PG279q issues

[magicammo]

Hello I'm hoping someone can help me. So my monitor is acting up. When I turn it on the screen comes on then the display turns off, then on then off again. What could this be? The main board? Power supply? Some caps? I don't have proof of purchase so I can't RMA even if I could the date on the monitor is for may 2017 and that's past the 3 year warranty 😭

Do you have another pc to check if the monitor is the issue?
