Hey, sorry to hear you are having these problems. I know that can be frustrating. Hopefully, we can get you back to work quickly. I see no one could help you earlier, and I hope this is not too late to be helpful. Please note that I am not set up for phone calls, you can ignore the site pop-ups. We can post to this chat as much as you like to work through this issue. All experts are not employees, and we work from home in our spare time to answer questions.

I would first look at the machine controller ECM. It has three lights in a small window for tattletales.

If no lights are on (when the key is on) that means no power to the ECM. A red light is likely a failed ECM and a yellow light means no communication to the monitor.

A green light is on when the system is powered.
