Levinson 37 Error: 0C

Fellow audio nuts,

I just recently I started receiving an ERROR: 0C (that's a zero) on my ML37 Transport. Has anyone else seen this or know the cause/solution? I assume the ML39 and ML390 may show the same error.

I am just trying to see if it is something easy for me to fixed or reset myself vs what will be an expensive repair no doubt.
