Question Samsung monitor, no sign of life. Help please

[General Shao]

I was given a Samsung - CHG7 Series C27HG70QQN monitor from a relative because it no longer works. When connected to the original power brick, no blue light or sign of life. Bought multiple aftermarket 22v 4.5a power supply to no avail. Tried the power cycle I've read on forums too. I have it opened up. Any help or direction? I'm not savvy with these things.
