Acer monitor going blank after a while (audio still working)

Hello again Reddit, I’ve posted before and I’m still trying to work on this monitor,

I’ve successfully replaced what I believe to be the problem caps on the control board but I’m just wondering if there is any obvious problems with the power board that experienced eyes can see,

Does anyone also have any tips or tricks to fix this problem?

I noticed there is a bit of a flicker when the screen goes blank

I have PROPERLY uninstalled and reinstalled the nvidia drivers updated the bios and changed all the cables between hdmi and display port as well as played with the refresh rate and resolution settings
