I have a  Mitsubishi HS-U545 VCR that displays an error code of "E5".  If I disconnect the power for a time and replug the unit back in the mains, the error code goes away until I put in another tape.  Then the error code comes back on and the unit won't play the tape.  What does error code "E5" indicate and can I fix it myself?  I understand the error code "E5" on some other Mitsubishi VCRs indicates it needs head cleaning.  If that is the case, what do I need to clean the heads?
Thanks,
Randy Evans
