Panasonic DMR-E55EB cooling fan appears not to work

Posted by on

1 Answer

The fan is thermostatically controlled - it only works when the unit gets hot. The hotter it gets, the faster the fan spins.

My panasonic dmr-eh75v won't stay on. It turns off after about two minutes. What could be wrong?


Check the cooling fan on the rear panel. If dust builds up on it the fan blades won't turn and the unit will overheat and shut itself off.

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..

My dmr-e55 dvd recorder will try to do a seif check but keeps going back to the beginning, and also i have notice'd that the cooling fan does not work, but after sevral attempts it does come on.


Hi there,

One possible cause of this is there is a known fault with the DMR-E55 where it goes into self check with intermitent shut down, so much so there is a mod kit available to try to overcome this. The kit costs around £20 online. However the kit composes of componants that need to be soldered into place and I stress this should only be under taken by trained technicians as further damage could occur, also the removal of the cover exposes potentially live electrical parts. The cooling fan could also indicate that there is a problem on the circuit board or the fan is on it's way out and needs replacing. My only recomendation is to take it to a Panasonic registered repair centre.

Hope this helps,

James

Panasonic dvd recorder model dmr-e55eb/ebl. played dvd,no problem - ejected dvd - green/blue colouring appeared on TV which disappeared when dvd recorder switched off. since then unable to play dvds. ...


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..

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...
