Hello, U80 is a failure within the Panasonic player itself per the manual (see the error codes on page 62):
What this typically means is either the processor of the machine has locked up, or there's a hardware failure requiring service. Please unplug the Panasonic from power (unplug the power cord), then press and hold the power/standby button on the machine itself for 10 seconds and release. Wait a minute then plug it back in, and press power/standby once to turn it on.
Let me know if you have the same problem.
