Question about Panasonic DMR-EX75EB-S DVD Recorder/HDD Recorder

Open Question

Panasonic dmr ex75eb will not tune digital freeview. Was ok and then just stopped! Will tune analogue. In setup the 'signal condition' box is greyed out. All connections secure - via HDMI - and TV with freeview connected to the same aerial tunes ok. Have tried resetting to 'factory condition' but problem still there. Is the freeview tuner at fault in the dvd recorder? Therefore will it cost more to repair than it could be worth.

The reason your dvd recorder keeps self checking is because there is a faulty regulator on the power board.

I have listed full instructions on how to fix this, but you will need to be able to use a soldering iron and exercise care. Alternatively you may be able to pass the instructions to someone who can repair it for you.

Do not listen to anyone telling you the laser is faulty, DVD drive unit is kaput, it requires firmware, software or any other useless upgrade, or that Panasonic will do it for the price of a small car! It is easy to fix..

I won't repeat the instructions here but if you look at my profile and search my DMR E55 solutions you will find it.

The regulator gets very hot during normal operation and it will eventually fail on all DMR E55s after a couple of years or so.
It was probably on its last legs and when you put the lead back in, you probably didn't disconnect the plug from your power socket and this caused a power surge which has finally killed it.
If you know what you're doing it's an easy fix.
It definitely does not need a software reboot.

I would be reluctant to use it again until it has been fixed because if the regulator overheats further, it could short circuit and cause other components to fail which would make the repair more difficult.

To check to see if there is a disc inside, unplug the unit from the mains, remove the two large silver screws, one on each side, then the three black screws on the back of the lid which can then be easily removed.
Next, remove the four small phillips screws that hold the top cover on the dvd drive. This is a large black plastic cover in the middle of the unit. The cover can then be taken off and disc removed if there is one inside. DO NOT TOUCH ANYTHING ELSE. replace the cover and screws, then repair the unit.

Is your recorder hooked up to the new convert box for digital antenna reception?
I am currently researching the convert boxes for my dvd recorder. I found that some dvd recorders already have digital converter boxes already installed. This might be the case for you.

SOURCE: My DMR EX75EB it fails

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 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 code' 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 model previously. The DMR-EX75 and DMR-EX85 are prone to U81 - which is a common error code.

Can't tune in tv with dvd freeview.it states ext link problem


If you've connected the DVD to the TV via HDMI or SCART you shouldn't need to 'tune it in', just select the HDMI or SCART input. If your TV is also a Freeview device and you want to tune it to Freeview, where you have the aerial connected to the DVD recorder, you need to also connect the DVD recorder to the TV via an RF cable or aerial flylead so that the aerial signal passes through the DVD recorder. It's all in the instructions

When connected to the Panasonic DVD player I get a message when on One HD and any channel above that - "Unable to decode HD". How can I connect to these channels through the player?


You can't, without an external HD set top box connected via the recorder's inputs. HD is not a standard digital tuner format for this or any model Panasonic DVD recorder that I am aware of. Panasonic do not offer a way for the user/owner to skip the HD channels (which cannot be decoded) in these units. You can only skip analogue channels in VCRs/DVD recorders (which feature an integrated SD digital/analogue tuning system) - stupid really. It just means you need a separate box to get all the available HD channels through the unit.

Yes, 7mate (channel 73) is HD (but it isn't specified on their website or in the EPG) as is Gem ( channel 90) and of course One HD.

I assume your machine has a built in SD digital tuner.

I cannot get any tv channels though my panasonic


This model only has an analogue tuner so wont receive anything if the analogue signal in your area has been switched off. either buy a new new with a freeview tuner built in or just use that one in conjunction with a freeview box.

Can not get any digital progams now that I have retuned my panasonic dmr-ex75eb dvd recorder. Am not receiving any digital signals


You may lose some channels when you retune the TV as the channels have been rearranged. To locate them look at the EPG although you may still find that some channels are no longer available on FREEVIEW. See the following link for additional information

http://www.freeview.co.uk/_retuneinfo/

If the above process does not work then check the link above for additional information and also visit the accompanying site links below to find more information for your model of TV / FREEVIEW box.

Recording and viewing different channels


The EX75 has only one tuner circuit, so you can't watch a different channel from the one you're recording. To do this you will either need a set-top box for Freeview or a Freeview compatible TV.
