When I plug it to the AC the power LED (blue) turns on but the screen won’t show anything. The screen leds are not even turning on so I suppose it has power related shortcut.
@chaingunjoe this series had an issue with the power board. Disassemble it and take a look at the board for leaking, domed capcitors. Postsome images of your boars with your question so that we can see what you see. Use this guide Adding images to an existing question for that.
Try to connect to any other display device by using same hdmi cable if that too having the same issue change the cable and try again if this doesnt work for both the displays there must be a issue.
