Question about Panasonic DMR-E55 DVD Recorder

2 Answers

DVD Recorder keps re-starting self test & will also not finalize discs.

My 2 year old Panasonic DVD Recorder DMR-E55 started having problems finalizing discs, it just wouldnt do it any more. Now, the last disc I tried to finalize is still in there, presumably still not finalized, and the machine keeps starting its self test when it is turned on. It starts self testing, for about 3 or 4 seconds, then the display goes blank, then it starts again. This goes on forever. I have tried turning off & back on again (the ultimate IT solution) but this didn't make any difference. I cant eject the disc to try starting it with another one, because the machine wont come out of self test mode.

Re: DVD Recorder keps re-starting self test & will also...

I am surprised to hear that after you replaced the IC, machine is now dead.
I think you should check your soldering, use a magnifying glass to see if you have not broken a track or shorted something.
There are some small parts surface mounted under the board near this chip.
Next , check other soldering , especially on the chopper transformer.
Third, check if you have connected the supply output connector correctly and no pins are bent.
Good Luck

This seems to be a common problem with the E55 and E85 models, could be one of two things, either the RAM Drive or the Power control ic (STRG6353 primary side of PSU), i would suspect its the latter. You'll need an engineer to replace this component.

Self checking

I have had a Panasonic DMR-E85 with this exact same problem you are describing. As I bought a Freeview Dual-tuner PVR I just bought a second-hand DMR-E55 as I liked the Panasonic interface. Two months down the line it is now exhibiting the exact same problems, except now as well as the continual self-check rebooting, it's also refusing to eject the disk. Booo. Time for me to buy a new DVD recorder again, and this time certainly not Panasonic... :(

How do i finalize a disc

..issues with the DMR-E55 recorder: is your manual:

...and on page 33 of that manual they discuss how to do the finalizations.

From my experiences on a friend's DVD recorder,
you need to go 'step by step' and in exact order or the processor
in the machine may not see the correct labeling codes on your disk
at the time you finalize. The "problem issues" referenced in the first
link should help you keep from stumbling over an 'error prone' situation
and may/may-not apply, but IF it does please contact your original sales location with that information.

Will my non finalzied discs play on a panasonic ez 28 or ex 768

You will have no problem playing your non finalized discs on any of the Panasonic DMR range including the DMR EZ28 series. The DMR E55 can also easily be repaired if you can use a soldering iron and a little care. Please checkout my other postings for full repair details.

DMR E55-P will not read DVD-R

Hi Benyto

Thank you for the information. Sorry that you are having such problems.

Nearly all the problems on ths DMR E55 are due to a faulty power board. The greatest load on the power supply is when the unit first reads discs and also when finalizing. Sometimes the unit cannot read discs and sometimes it continuously self checks.

Try replacing IC001 on the power board. This is a 5 pin regulator #STRG6353. This component gets very hot and the heatsink is poor. When I replace these, I use a larger heatsink and some heatsink paste which helps to prolong the life of the component. If you look at the regulator, you will see by the colour of the circuit board that it gets very hot. It fails after two or three years in all DMR E55s.

Be careful when you take the old regulator out because the print can lift away from the circuit board.

I have posted full instructions on how to replace the STRG6353 >HERE<

Hope this helps

Hi Audi,
Try unplugging the hdd & then turn on the dvd recorder & wait for about 5 minutes.
Then unplug the dvd recorder & plug in the hdd & turn back on the dvd recorder to see if that fixes the problem.

Panasonic DMR-E55 DVD Recorder Problem

I have been told that panasonic now have a faster speed disc on sale to suit the newer dvd recorders that dmr-e55 cannot record on as they are too fast. You have to buy the slower speed ram discs to suit the dmr-e55.
