SC 819 on a MP500, After i fit a new controller board i get an SC 998 that is persist

[Venom]

I would update firmware using an SD card, follow instructions in manual, ie: leave front door open when updating

I am not familiar with this particular machine, but I do know that some controllers have a very small eprom( its like an 8 pin) that you must remove from the old controller and install onto the new one. If this is not done you will get a SC819. Just a thought.

I assume that you have follow steps on replacing controller and nvram...
upon having a SC 819... have we upgrade the firmware? perhaps this may solve the problem....
can we try to afix the old controller and nvram and make an isolation from there after backing up nvram data... put the new nvram then upload and see whats the result or place the new controller and afix the old nvram.....

good luck sir...
