Question about Televison & Video
SOURCE: hdd error
try replacing the red sata cable which runs from the HDD under the DVD drive to the main board on the right-hand side. these are a common problem on these models, there cheap and unreliable. you can purchase a better quality cable from a computer store for little money. HDD ERROR is'nt necessery an HDD fault as i found out with my rdr-hx525. if however the HDD is faulty and you buy a replacement, once installed you will need to pair the new HDD with the unit by entering the service mode by unplugging the AC then while holding down open/close and play together then re-insert the AC lead while still holding open/close and play and wait until you see an "S" in the display then let go and the service mode will appear on the tv screen. go to no.9 HDD mode, press enter then go to no.3 Write ID then it will say "execute write ID?" yes and press enter and then it will say "writing HDD serial ID.... OK" once this is done, exit the service mode by keeping your finger on the power button for approx 10secs. your DVD recorder should now recognise the new HDD. if you don't follow this process, you will still have an HDD error message as your DVD recorder will have your old HDD installed and won't recognise your new one. given the amount of time since you posted this fault, you may still have the unit in question in which case i hope this solution is helpful, or for anyone else with the same problem.

Most have "hack codes" but yours is in a select group of a few that simply cant be done with a couple pushes of a button.
As far as I am aware the only way to get thesemachines to play Region 1 discs is to have them chipped. A variety of solutionsare available, and it needn't be expensive (typically £30 to £70) but youshould be aware that any internal modifications to your players wouldinvalidate the warranty. Have a look at the following web sites for moreinformation:http://www.techtronics.com/uk/shop/50-000-dvd.html
I know you were looking for a free solution you could do in a matter of seconds and sorry it didnt work out that way. Regardless, I hope I pointed you in the right direction and feel free to ask if you have any more question.

These are error codes generated by the main microprocessor which are
tripped by corruption, preventing it's operation and which requires the
processor to be reset.
The codes do not actually mean anything at all because the corruption error potentially has a great many possible causes.
It does not point to any specific fault as such.
U81 error literally means 'Microprocessor Communication Error on the Universal asynchronous receiver/transmitter' but I dare say if Panasonic told you that , you would be no further forward.
Corruption can arise for many different reasons .. and is not surprising in a box that has an aerial feeding endless streams of complex data into it, has a mains connection with interference on it, has two internal data storage and retrieval systems, either of which can be problematic... and sits permanently bathed in electrical and radio frequency fields of varying intensity.
Causes can be difficult to identify and may be internal or external.
Such problems may be exacerbated during the transitional phase of the DSO [ Digital Switch Over ]
In practice, all one can do is follow good practices:
Don't stack gear - or give it plenty ventilation if you do.
Ensure good clean mains supplies.
Ensure a properly installed aerial system with sound connectors and adequate screening.... etc.
