ACD led lights turn off when connecting

[gugy]

I have a 30” ACD that was working fine and out of the blue stopped. The weird thing the led light is on when the display is not connected to my Macbook Pro but when I connect it, it turns off and the display won't turn on with no signal. Right next to it, I have another ACD that won't do this.
I have the MBP Max with the latest with the monitors plugged using DVI to USBC adapters.
If anyone have any ideas, I appreciate any feedback.
