Hi there, this is what Panasonic say.... The "U99" error code signifies a "general communications failure."
It is not associated with one specific problem.
It can be related to the version of firmware your DVD recorder is currently using and it has been associated with the TV Guide on screen guide.

If your unit displays U99, turn the power off-unplug the
unit for 5 minutes, and reconnect the power.

If U99 reoccurs, please contact the Global Service Center Network for assistance.

How do I fix my Panasonic DVD Recorder DMR-XW380


U99 Hi. This indicates a communication error between the timer and main processor unit. Try unplugging from the wall for a minute or two, and plugging it in again, to reset everything.

We recommend you remove all speaker cables and HDMI cables from the system. Then turn the system back on and see if the U99 message appears. If it does, then we recommend having the system evaluated by an authorized service center using the below link.

You can probably fix this issue by updating the firmware and doing a system reset. First, download the latest firmware and burn it to a CD. You can download it from here: http://www2.panasonic.com/consumer-electronics/support/Video/DVD-Recorders-Players/DVD-Recorders/Drivers-Downloads/model.DMR-EZ28K.D#ts

Now, power the unit down, press Skip/Rev + Time Slip + Open/Close for 5 seconds. The CDR should be in the disc drive as you do this. This will install the new firmware and re-initialize the system settings.

The complete manual is here: http://service.us.panasonic.com/OPERMANPDF/DMREZ28-MUL.pdf

U99


A U99 error code signifies a general communications failure and is not associated with any specific problem. It could even be related to the firmware version of your DVD recorder.

Try turning off the power and unplugging off-unplug for at least five minutes before reconnecting.

If U99 reoccurs, you should contact the Global Service Center Network for assistance.

Good luck!
