Hi Bought a Panasonic DMR-EX75 to-day and the unit keeps on failing with error code U80 mainly when in freeview and channel changing. I have looked in passed posts on forums and have found " the error indicates that there is a either that poor quality or damaged discs are being used or that the laser is failing. It is a self-diagnostic fault code, possibly requiring attention by a qualified engineer". IS THIS A COMMON PROBLEM . You can clear the fault with powering off the unit to stand by but the fault re-occurs . Was this part of the ealier recall issues?
