Hi, hoping someone might be able to help. I’ve had the above machine for a while and it has been working without problem. After briefly playing on it a couple of weeks ago, and I did open up the top but didn’t think I knocked anything, it now only turns on with the alarm and in the display is unused input error 8000000 alarm 90-4D. Does anyone know what this might be and how I can fix it?
Many thanks in advance.
