I have a DMR-EX75EB and a couple of times the screen has gone blank and the error code U80 is displayed on the panel. If I change the channel it is OK again for a few minutes then does it again.
It records and plays back fine, it is just when watching Freeview TV that this happens.
It is only a couple of months old so is still under warranty, has anyone any ideas what the error is please. It is not in the manual.
