Also here is an update: I was looking through old photos of when the fuse first blew out and everything happened.
First it gave me “Error 61302:65535: Inverter Command Error”, which forced me to reboot.
Next on the reboot I got an error message on my printer LCD screen “Inverter Update: Erasing Sector 0” and the screen when blank afterwards.
After that it has been the same problem as stated in the first string.
Is it possible that the flash was wiped? If so, how easy/hard is it to reinstall everything to it?
