Question about Panasonic Televison & Video

Open Question

Panasonic DVD Recorder DMR-EX98VEB keeps displaying 'U81' which I can get rid of by switching off and on via the unit's switch, but it affects recording - won't start recording or it records black.

Also, when the 'U81' is displayed you can't see any other display, e.g. the time you have been watching a recording, etc. When I get rid of it, the orange DVD light flashes briefly on the unit before it returns to normal. Have tried unplugging, waiting and restarting, plus returning settings to shipping condition.

Try updating the firmware (software) on your player, if not you might need to send it for service to a Panasonic authorized service center.

I figured out, unlike all the other posts, you don't have an enter button. But Instead, you would hit the 2 and OK button at the same time for a few seconds. I had the RC1 message and I did the 1 with OK and it worked. so if you have RC2, you should hit the 2 and OK. Should work!!

SOURCE: DVD recorder DMR-EX78EB - Keeps

This is one of several error codes generated by the main microprocessor IC which are tripped by corruption, preventing proper operation and which may require the processor to be reset (where practical) or replaced.

The U81 and U80 codes don't mean anything in particular because the corruption error(s) could be caused by a number of different reasons. It does not point to any specific one fault. This is where the confusion sets in as to the origin of the 'error codes' in any device.

U81 means (in technical terms) 'microprocessor communication malfunction' on the universal asynchronous receiver/transmitter' or 'microprocessor feedback information error'.

This is not something the user should undertake to repair themselves; it should really go to an authorised Panasonic repair centre. The cost depends on the parts used and the labour, however, it is not unfixable. You can always get a quote on this and a second opinion, then decide for yourself if it is economical or not.

I posted this 'advice' for this (and a similar) model previously. The DMR-EX series of models are prone to U81 - which is a common (and extremely irritating) error code. As I said, it is not unfixable, if you are prepared to spend a fair amount of money on the repairs by a qualified service technician in a fully equipped workshop with access to all the required components and service manuals.

Certainly worth investigating at least.

U81 is permanently on the screen, I cant get the TV listing menu, nor can I get it to record, can you help?


U81 error literally means 'Microprocessor Communication Error on the Universal asynchronous receiver/transmitter'.

This error can be caused by a number of different reasons but one of the most common is a software / firmware problem relating to the Freeview part of the unit.

If you turn the unit off for 30 minutes it should reset the fault.

At this point to need to check what version of firmware you have installed and then check the Panasonic website for your country for the latest version.

My dmr-e50 ca not play any disc it display dvd drive eror


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.

Error code U81 onDMR-EX75EB Unit will not power up, keeps shutting down


I have posted advice on the possible cause behind this error code (as well as other members on FixYa) for this model DVD recorder previously. For you I will re-iterate:

The U81 error code is a common problem
with many Panasonic DVD recorders of the DMR-EX series.

This is one of several error codes generated by the main microprocessor IC in the unit which are tripped by corruption, preventing proper operation and which may require the processor to be reset (where practical) or replaced.

U81 means (in technical terms) 'microprocessor communication malfunction' on the universal asynchronous receiver/transmitter' or 'microprocessor feedback information error'.

This is not something the user should undertake to repair themselves; it should really go to an authorised Panasonic repair centre. The cost depends on the parts used (if available) and the labour, however, it is not unfixable. You can always get a quote on this and a second opinion, then decide for yourself if it is economical or not.

(sometimes unplugging the unit from the power point for up to 30 minutes, then reconnecting resets it completely and clears the error code with no further remedial action required)

Usually when this error occurs, and persists, the unit cannot be reset by the user. In your case, the constant shutdown may also likely be a fault in the switchmode power supply as well as a problem with the microprocessor. It may or may not prove an expensive exercise.

Certainly worth investigating at least.
It's up to you as to what you decide to do from here.
I hope I have shed some light on the subject for you and similar people who have experienced this particular error display.

My DVD RECORDER MODEL NO DMR-EX75EB, THE CODE U81 KEEPS COMING UP WHEN I SWITCH ON MY RECORDER, ALSO I CANNOT GET INTO MY SETTINGS TO SEE IF I CAN FIX IT. THANK YOU

I posted this 'advice' for this (and a couple of similar models) previously. The DMR-EX series of models are prone to U81 - which is a common (and extremely irritating) error code. As I said, it is not unfixable, if you are prepared to spend a fair amount of money on the repairs by a qualified service technician in a fully equipped workshop with access to all the required components and service manuals.

Because of the malfunction, the user settings and options are inaccessible, and there is no official user-reset option on this or any model of the series to clear this particular error.

Certainly worth investigating at least, as Panasonic usually make great products.
It's up to you as to what you decide to do from here.
