So my AJV-18N went down 2 days ago. I determined that the issue was with the spindle drive. After getting a troubleshooting guide from Mitsubishi, I determined that they issue with that spindle drive power supply had gone out. Yesterday I was able to swap a different power supply and get it running, unfortunately the same thing just happened today. So there is probably something else going on that is causing to power supply to fail but I am not currently getting anywhere with Mits as to how to trouble shoot it any further. Any ideas, thanks!
