Question about Panasonic DMR-E85H DVD Recorder

Trouble with my Panasonic DVD recorder DMR-E55EB


The machine is 2.5 years old & in the last month or so it has started to not recognise all discs.  Upon putting in the majority of discs (RAM or normal films) it seems to 'self check' & 'read' over & over again, then shuts down, then repeats the process over again. When this happens I can't eject the disc & even unplugging the machine won't work.  It all started when I tried to record & it kept turning off the record mode within a few minutes.  Every now & then it will play a disc perfectly but more often than not it doesn't.  When it is 'self checking' & 'reading' it seems to make a werring noise.

It has not been used greatly in the time I have owned it.  Any ideas?

Try using a CD lens cleaner first. If that doesn't help, it could be a problem with the lens itself being scratched, etc. You will have to open the cover up and try a manual cleaning of the lens and blowing around with a can of compressed air to clean any dust / debris.

If that does not help, then you will most likely have to replace the lens. If that be the case, I would suggest buying a new player, as it would work out cheaper for you..

Hope that helps!

    Try this:
    To initialize ALL parameters to factory defaults: With the unit OFF, press "Skip
    Rev" ( |<< ) and "Time Slip" and "Open/Close" for 5 seconds.

    If that doesnt work, you can try to Download the Upgrade File
    . Extract the zip file to a folder in your PC and burn it onto a CD.
    This should be a regular DATA CD. So select the appropriate setting in
    the burning software. I assume the unit observes the filename's
    extension and then validates that it is an upgrade file. I think it
    also compares the CD version with the currently installed version and
    does not do the upgrade if the one on the CD is the same or an older
    version. You simply put the disk in the unit and it will take it from
    there. It doesn't take long. It opens the DVD drive at one point. Just
    take the CD out and close the drive. After a while, the unit shuts off.
    You then power the unit up again and you should be good to go.

    If that does not work, you may have to change the power supply regulator and add some extra heat sinking. You only have
    1/4 of an inch between the top of the heat sink and the bottom of the
    HDD carrier but adding a piece of aluminium sheet to soak away any
    excess heat may mean you only have to replace it once.

    It could also be due to due to RAM drive failing, in which case this will have to be replaced.

    If all else fails, try calling Panasonic customer care at 08705357357.

    Hope that helps! Should you have any further questions,
    please post them here.

    Is this after downloading the upgrade or after the initialization of player to factory default?

    Try connecting the player to TV via the AV1 output and play a disc..

    You only need the *.frm file to be burnt onto the disc and you *must* fnalize the disk .

    It should be on a CD (I don't know if DVD will work), and the drive select on the DMR-E85 should be set to DVD and not HDD.

This might be a hardware failure on the laser that reads the information from the DVD.
I would suggest to try using a lens cleaner and see if that helps.
Let me know if you need further assistance.

Am afraid that this is indicative of a weakening optics or the laser. You can of course still give it a cleaning using CD ROM cleaner normally used for computers. Additionally you can try using a can of compress air to force out any dust inside the unit. Other than that all other actions would require opening the unit for a look and see, manual cleaning or worst case scenario, parts replacement.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

I have an 'old' DMR-E55EB recorder with my latest two RAM discs suddenly being 'write protected' without me knowing why. Is there any way to make them work in a read, write, and erase way again? If...

Very strange, but not uncommon.

The DMR-E55 (and its variations) is a 2004 model DVD recorder, so it is over 5 years old. If you did not set write/record protection on those discs, then it is likely to be a defect within the recorder, which may require workshop attention. You can always submit the unit to an authorised service centre for a quote and second opinion, to get an idea of the likely cost(s) involved, if a fault is found, then make a decision afterwards. Up to you.

Alternatively, it might be a good idea to cease using DVD-RAM discs and use DVD-RW/+RW discs instead if the unit accepts these as a recording format (or change brand of disc), and you intend to record more than once per disc. Or you could try the same discs in your PC if it has a DVD burner which is capable of reading/writing RAM discs as well as all other formats. If that works, the discs are OK.

If this does not work, then your only other option is to take the recorder to a workshop and have a qualified technician examine it thoroughly; but be warned - it may be expensive if you decide to do so. I hope it is nothing too serious.

Model DMR-ES30VEB. I have had this recorder for a few years now but since I got a new Sony TV at christmas I am having problems recording. When I record a programme the DVD says it does not recognise the...

DVD-RW discs are ideal for temporary video recording and data backup, but they are not recommended for successful finalising, as there is no guarantee that the disc will work in another device.

Have you tried using DVD-R discs? these CAN be recorded in video mode AND finalised for compatible playback in other players. I assume the DMR-ES30V is a DVD/VCR combo unit - if so, the DVD recorder will not recognise RW discs; only DVD-RAM and DVD-R.

DVD-R discs are recommended for video recording and finalising in this model. (later model Panasonic DVD recorders allow RW disc recording).

DVD recorder not recording any more

I have found that you get what you pay for in electronics. I bouoght a Cyber Home recorder, it lasted about 15 months before it went out.
I had another off brand ( don't remember name) that also didn't last. I have an older, I think it's a Panasonic, at least 5-6 years old. It won't reord on DVD+R, only on DVD/RW discs.
So, first I say you bought ****.
Buy name brand only it lasts longer.
Second, these things don't last to long.
I have a player only that is 5 + years old that still plays movies.
I haven't used the Panasonic for about a year. I do use it to PLAY movies still.

This is a problem with either the logic or the power supply. Without seeing the machine and taking measurements inside, I can't state for sure the exact problem. These are decent machines. I would suggest that you bring it to an authorized Panasonic service center for a repair estimate. Post the results here and we'll suggest the next steps.

Trouble with my Panasonic DVD recorder DMR-E55EB

Hi Dengle

The heat is caused by IC001 which is a regulator that is mounted on a completely inadequate heatsink on the power board. This component gets very hot during normal operation.

The regulator will usually last a couple of years, depending on how often the machine is used and then start playing up. The symptoms are intermittent operation, continuous self checking and rebooting, not being able to read discs and so on.

Eventually the component can short-circuit, burn out and take other components with it. The on-board fan is thermostatically controlled. It does not operate all the time, only when the unit gets hot enough. By using an external fan, you are keeping the unit cool enough for its own fan never to cut in. The additional cooling is probably squeezing a bit more life out of the regulator and is stopping its own fan from operating.

I have repaired lots of these and have never found a faulty fan, or fan switching fault. There's always a first time of course.

It is more likely that the regulator IC001 is faulty and if you are technically skilled, I would suggest you seriously consider replacing it. Use some heatsink compound and an extra heatsink, and it will probably do the trick. The regulator is an STRG6353. You can get these easily online from a number of outlets. Don't attempt a repair if you are unsure of what you are doing. Regards..
