Unfortunately, none of that will fix your machine, as this is a common fault with these units.
Fortunately though, it can be fixed.

In 99% of cases this is caused by a faulty regulator on the main power board.

The power board is located on the right hand side of the unit. The regulator is IC001 which is mounted on a thin metal strip which acts as a totally inadequate heatsink. This means that this component constantly works at temperatures beyond its tolerance.

Because of this it usually lasts a couple of years and then starts causing problems. The Self Checking syndrome is typical. If the regulator burns out completely, it can take other components with it, blow fuses and scorch the circuit board.

If you are competent in using a soldering iron with care, order an STRG 6353 regulator. These can be obtained online from a number of suppliers.

Disconnect your DMR E55 from the power source and remove the lid. Next, remove the fixing screws from the circuit board on the right where the regulator is located. Carefully remove the multi connector on the left side of the board. Remove the screw above the power connector on the rear of the unit. The power board can now be removed from the cabinet.

Using a small pair of wire cutters, clip all five pins from the old regulator as close the the top of the board as possible. Undo the screw securing it to the heatsink and remove the old regulator which can now be thrown away.

Next, using your soldering iron, remove what's left of the pins from the printed board and with desoldering braid, clear the holes ready to accept your new regulator. Be careful because if you over heat the print it can lift away from the board.

Use a little heatsink compound on the back of your new regulator, poke the pins through the circuit board and then secure it to the heatsink. I usually fit an extra heatsink on these units which helps to reduce heat and prolong the life of the new component.

Next, resolder the 5 pins on the print side of the board. Use a magnifying glass and make sure you haven't missed anything or bridged connections in error and caused short circuits.

Now put the board back. This can be a little tricky but it's easy enough if you take care. Refit all the screws and carefully reconnect the multi connector.

If you have followed this correctly, switch the unit back on, pop in a DVD and give it a try. Unless you are very unlucky, Your DMR E55 will no longer repeatedly self check and will operate correctly.

Whilst it saddens me to hear that some of you guys would toss your DMR E55s into the trash can for such an easily repairable problem, please do not attempt this unless you are confident in your own ability.

If anyone tells you the laser is shot or the drive needs replacing, take absolutely no notice of them because they don't know what they are talking about. The above solution WILL fix your machine if you follow the instructions correctly.

Finally, do check that the fan operates but remember it is temperature controlled and will not activate until it is needed. Do not assume it is faulty because you do not see it working straight away. I have repaired lots of DMR E55s and I have never found a single fan or fan control circuit to be faulty. That's not to say it can't fail. good luck

Trouble with my Panasonic DVD recorder DMR-E55EB


Hi,

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.

Self check


Try a hard reset: Unplug the recorder from the power socket and TV, wait about 5 minutes and replug into the power socket and TV.

Please try that first and let me know how it goes..

Starts a self check then power goes off


Not sure if this will help. My machine was stuck with a "Please Wait" message. Searched internet, many folks with problem. The fixes all pointed to 2 capacitors being blown. My brother was able to easily solder 2 new ones in and the machine worked perfectly. If you Google the name and model with Please Wait after it, you will see some of the conversations and remedies. Your machine may be heading toward this problem.

Also, beware of storing too much on your hard drive! My machine was working great after the above repair, but I believe I had too much stored on mine and I got a U99 Error Code. Service Center said it can not be repaired and THEY DO NOT MAKE THESE ANYMORE. There are DV machines with a hard drive so you can watch shows, but not to record show/movies. I make DVDs of my son's high school games. Can edit and transfer many games at once with this machine... not with any others!

Do not let this one die on you. It is priceless.

Get a laser cleaning disk, and follow through with the instructions about how to clean the laser with it.

If you are able to remove the DVD player drive, you can manualy clean the laser.

If cleaning the laser does not fix the fault, then this means that there is a failure somewhere else in the drive, or the laser itself is defective. Most of the time, these drive's are not worth servicing.

No disk error after dvd is loading


Please use DVD drive cleaner and get head cleaned. Then load the DVD and if problem still persist then there is problem with the lens. Call the engineer and get the lens cleaned or replaced.

Stuck in self check mode


Manually pull down the front shield, then somewhat forcefully pull down the inner shield and maybe two little white pins so the tray is exposed with nothing blocking it. Have someone plug the machine in while you are holding everything out of the way and the tray should start to open. Pull your fingers out quickly so you don't block the tray from sliding out.

Replacement dvd reader/writer


To others with the same problem as i "Had"!!!
the problem was solved by once again strippng the dvd drive down and cleaning the lens. This time using more pressure than before. It would seem that the light clean I gave it before did not fully remove the dirt/grease film that had accumulated on the lens. By adding more pressure to the cleaner soaked cotton bud this did the trick.
After cleaning make sure no fluff remains. This can happen when using a cotton bud as I did.

A self-check for these models can sometimes last for 3-7min's (sometimes longer) depending on how much recorded data is on your hard drive. Plus it checks all unrecorded space on your hard drive as well. Don't forget that it must check 200Gig. If it self checks for longer than 20-30mins turn off at the wall and let cool down. Try again in an hour or so and it should rectify itself. If it continues to self-check for longer than 20-30mins refer your machine to an authorized technition

power up your dvd then you you disconnect from the power cord.wait a few mins like 5 mins then you plug it in back and power it up if that does not corect your problem.the strip that leads to your dvd lens needs to be changed.or the micro chip that controls the hd needs to be changed.however take it to a tech.
