HDD ERR is quite a serious error, as it means there is a hardware problem with the internal disk drive. You could try switching off the unit and disconnecting the mains cable overnight, and trying again, but really this will need to be a call to an engineer.

If your unit is still in warranty call them now to arrange a fix. To find your local warranty centre, go to your regional Panasonic website, and look under Customer Support

I have the cigarette plug for this. I found it in my tech "graveyard" and didn't know what it was for, until I searched on the serial number.
If you want it, please let me know. You can have it for the mailing cost. I don't need it/don't want it.
