How can I tell? I have thus far replaced the MC Board and cables to the AP Board but same problem.
I have to replace the AP board - waiting on support.
The issue started when X1C kept dropping off line and I had to cycle power. Eventually, it just died. The display still works (but sometimes freezes on the splash screen). Wifi connects but printer head not mobvable from screen. Can not otherwise reset, etc.
