FT-736R "Error" message

My FT-736R is out of service due to what I believe was a transient that came in 
through the PTT line.  I know for sure that it blew the main processor, which I 
have replaced, but now my display reads "ERROR."  I have yet to troubleshoot 
futher, but thought I would see if anyone has had this problem.

Does anyone have a list of troubles that could cause an "ERROR" display?

Thanks
