So, I took a gamble and replaced the already good Regulators. The EZB still doesn't work. All of the voltages are there. D1 has opened up and doesn't show any transistor or resistive, or capacitive readings, just completely OPEN. I need to know the value so I can replace it as a last shot at this. I have believed it was the cpu from the beginning. They used to sell those in the store for $15 , I think. Now, I have found this diode open.
So, does anyone know the value? I am guessing 5v Zenier?
