This symptom typically points to either a failing main control board or a faulty display interface. The black or gray fuzz and screen flickering suggest the control board is having trouble communicating with the display, while the unit shutting off during preheat indicates the internal relays that power the heating elements may be failing.
I tagged a few videos below that can help you check whether the control board has failed and determine if it’s causing the problem you’re seeing.https://youtu.be/u0fiQ0mST8A
