Question about Panasonic DMR-EX75EB-S DVD Recorder/HDD Recorder
How old is the unit? Have you tried unplugging it for a half hour and restarting the machine? This can be caused by many things this U81 error literally means 'Microprocessor Communication Error on the Universal asynchronous receiver/transmitter'
I would make sure the unit is in a well ventilated area. I would also contact panasonic if the problem persists and see what they can do as far as repairing/replacing the unit at little or no cost to you. I can get you their contact info if you give me your general location.
