For above error, this is mostly caused by PCB issue, dirty PCB head contacts. Users can use erasers to clean the PCB head contacts. Some times, it can be also caused by head failure, users need to write the factory ROM from the same family and then disable heads and then run selftest again. Any way, the most common reason is PCB on this one, users just need to change one donor PCB with the same PCB number and clean the PCB head contacts, above error is usually fixed.
