I have A Ikegai Fx20 With 5T controles. Every thing works in manual mode.
In MDI you can enter data, but when you push start nothing happens!
You have to push Reset to clear data from MDI. In Edit mode when you
type first word then hit insert it goes to Alarm and gives PS 70 Alarm.
(Book says memory over flow) memory has been cleared by keys and
unhocking battery with power off. And yes all peramiters are set. I have checked ribbon cables and most of wiring. Swaped boards have extras that look newNothing changes. I am stomped!!!! I have two fx20's one is running fine!After lot of work on it.
