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.

I have the Panasonic DMR EZ28K and while in stand by mode and even while playing a DVD, the display will show U99. When this happens, the unit will not turn on to record whatever I have programmed. To...


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!
