My monitor has 3 problems. Are they linked?

1. When I turn off the monitor with the power button, it turns off. But when I try to turn it on again with the power button, it doesn't turn back on. I need to unplug the power from the monitor for it to start again.

2. When I increase the brightness to 75%, the whole screen starts flickering fast. When I go up above 80%, it flickers even faster.

3. When my Mac puts the display to sleep, but I move my mouse to wake it up, the monitor doesn't wake up, and there is a green light flashing once every 3 seconds on the motherboard,

My monitor only turns on when I plug it to the computer for the FIRST time. Even then, it only works 20% of the time when I plug it in. I often have to unplug and replug 5 times before it starts.

Do you know what is causing each of these problems?

Are they all linked?

What components are at fault?

Thanks in advance

It may be the power supply or possibly the backlight only.
