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 get the message to go away I have to turn the unit on and then turn it off. If I just press the off button once, the display will go dark but the unit will not turn on to record until as mentioned, I turn the unit on and then off.

What is the error code being displayed? is it U81 U61 or U99? U61 is likely to be a DVD drive error. U99 is an electrical problem, while U81 is a microprocessor feedback information error. Your best option is to submit this recorder to a qualified service technician in an authorised Panasonic workshop, for a quote, and a second opinion on the likely repair costs and/or parts involved. (it helps to be more specific when posting questions here about DVD drive faults so we can advise people properly on the best course of action to solve the problem (however a few consumers do not know what device error codes are and what they mean; this is understandable in many cases).

The cost to fix this unit depends where you go and whom you deal with. It is up to you, but be warned; if the unit needs a new DVD drive, this could prove expensive.

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.

U99 ≥The unit fails to operate properly. Press [POWER í/I] on the main unit to switch the unit to

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!

Saludos : Yo tenia el mismo problema. Mi dvd DMR-E30 tenia el
mismo problema . Codigo U99 . Y no funsionaba nada.
Entre a la pagina de soportes de Panasonic y baje el Firmware.
Luego lo grabe en un cd ,el cd lo coloque en la dvd y la dvd se actualiso automaticamente. La dvd funciona perfectamente tanto
con DVD-RAM como con DVD-R. Esta solucion la saque de esta
misma pagina fixya . Gracias Fixya. Att. LACF
