Question about Panasonic DMR-E55 DVD Recorder

Releasing Ribbon Cable

Having read on your helpful site that the likely cause of my DMR-E55's powering down problem could be the V.Reg. STRG6353,. I'm attempting to remove the board but can't seem to locate the release tab on the ribbon connector( as described by 'Chipps') and as it seems fairly delicate I don't want to force it. I'm probably being a little dense here but can you give me anymore detail. Also I've read that a compound is recommended to aid with heat dissipation - Should I apply it directly to the component and is it costly? As you can tell, I haven't done this sort of thing for some time.

    Hi Palmbeach

    Many thanks for all of the advice. I managed to release the cable and followed your suggestions for removing the V.Regulator which I've replaced using the compound. I've put it all back together this afternoon but unfortunately I now have no display or signs of life in the machine, although power is getting to it. I've also checked the ceramic fuse and that's OK.

    I've taken it apart again to look for anything obvious and lightly re-soldered the V.Reg.but still no joy. I don't think I've damaged the print but I guess that could be the problem.

    Any other suggestions?

    Many thanks

    Hi Palmbeach

    Sorry for the delay as I've been away. Board still not working so I'm tempted to take you up on your kind offer - I'm in the U.K

    I assume you're in the USA. If you are still OK with this please confirm your whereabouts and I'll check out postage costs.

    Many thanks again for your time

The ribbon is quite easy to disconnect. It is simply a push fitting. There are several ways to tackle it. Get a sharp pointed tool or large sewing needle. then carefully push it into one end of the connector at a right angle to the length between the join. If you use a magnifying glass, you'll see where the two halves of the connector join. You should be able to prise it up. Once it starts to lift, put your needle in the other end of the connector and lift that. It should pull away easily if you then put your finger and thumb at each end.

Regarding the heatsink compound. The reason for using this is to assist with heat dissipation. The idea is that it fills imperfections in the two surfaces that are pressed together, namely the regulator and the heatsink. This allows the heat to transfer more efficiently. Most people use far too much compound. All you need is a very thin smear on both surfaces before you press them togther. If you use more than that it will not make it more efficient, it will just make a mess.

Personally, I always fit an extra heatsink on these units.

Be very careful when removing the old component. I recommend using a pair of miniature wire cutters to cut the pins of the old regulator. Then remove the pins carefully from the board. The print will easily lift away from the board if you are not careful. It isn't a disaster if this happens but you want to try and avoid damaging the print if you can. Make sure the holes are nice snd clear before you fit the new regulator. Again a sewing needle is quite useful for this and less stressful to the print than solder braid or a solder ******. Also make sure the regulator is locked down tightly when you have finished. Again, just a thin smear of compound is enough.

Compound is not expensive, but you'll buy a tube, use a tiny bit and probably never need it again. If you have an engineer friend he or she may be able to help. Alternatively, take a look on eBay for the cheapest you can find.

Hope this helps, have fun and take care..

    Hi woboogie

    I'm really sorry to hear that. Unfortunately, although it's not a particularly difficult job for an engineer, if you have never been involved with this kind of work before, I can see how you can run into trouble.

    Firstly, retrace your steps. Pull out the power board again. Take a close look at the print with a magnifying glass. Make sure that you haven't bridged anything or splashed solder across the printed tracks. Then, I would recommend using an old clean tooth brush to lightly brush the back of the board where you have soldered.

    Carefully put everything back and double check that the ribbon is back in place correctly. It doesn't sound as though you have short circuited anything or the fuse would have blown. More likely, something isn't connected properly. Where abouts are you? If you are happy to cover the postal costs and can send me the board in a Jiffy Bag, I would be happy to take a look.

    Hi again

    I'm in the UK too. Please email me direct

    If you sandwich the board between two pieces of card, foam or polystyrene, then pop in a Jiffy bag, Recorded delivery should only be about £2.50

Panasonic dmr-e55eb-s

Hello Brian. Its not a Zener, it appears to be some type of polarised VDR or similar device. I have just literally one hour ago repaired an E55. I was about to replace the STRG6353 and had taken the old one out. I thought it a good idea to check a few components before going ahead.. I did a diode check across td3 and it showed short circuit in both directions. So I disconnected both ends and then it showed open in both directions.. Read a bit more on various forums and decided it was ok to fit the new STRG. I made a much larger heat sink for it. The machine immediately came back to lift.
If you want a bit of moral support e-mail me at johnatjbrewerdotfsnetdotcodotuk. Happy new year..

Removed and replaced internal fuse - unit is now dead


The chances are that you bridged the printed track with a splash of solder when you replaced the regulator. A short circuit like this will cause the fuse to blow. You can get replacement 20mm slow blow 2amp fuses quite easily. But before you fit a new one, pull the board out again and have a very careful look under a magnifying glass at your solder joints. Get a small stiff bristle brush and carefully brush across the joints in case there is a tiny ball of solder across two points. When you reassemble the unit, ensure that the ribbon connectors are central and fully pushed into the sockets. I'm sure you can recover your DMR E55 reasonably easily. Best wishes

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

Replacing IC001 STRG6353 maybe the reason on power board.
Be careful when replacing, it is attached to heat sink has five pins, closeby some miniture surface mounted parts.

Powerdown after a few seconds

Amazing - I have exactly the same symptoms on my DMR-E55EB - noticed the dead machine on 19/11/6 - tried several powerdown resets, gained a few tens of seconds operation each time, and after around 6 attempts it died completely. Will open it up and have a look...
