Question Monitor Screen Goes Black After A Few Minutes

[inyumen]

Hi everyone!

I have a AOC C27G1 that I bought last year. It never fell down or got a scratch even, so It's completely new.
Last week I was playing Valorant and suddenly the screen goes black, with the power light still on. I turn it off and on again, and it shows the AOC brand on the screen for half a sec before going black again. If I leave the monitor turned off for the night, and the next day I turn it on again, it does the same thing all over again, it goes black after a few minutes and if I try to restart, it goes black after half a second.
What can be the issue? Is it worth to try and repair it?
I already bought a new AOC C27G2 because I wanted a second monitor, so I was hoping to fix this one and have both.

Thank you for the help in advance.

My gpu is a 1060gtx 6gb. I already tried the pc with another monitor and it works fine. If I connect only the power cable of the monitor it does exactly the same, it shows the message "no signal" and then goes black and does the restart thing I described above.

Also it might be worth to mention that a few months ago, the right side of the monitor went a bit darker than the rest of the screen.
