Re: DMR-55E dvd recorder timer fault
This is a common problem with this particular model. I can tell you what the fault is but unless you feel confident in using a soldering iron, the repair is best left to someone who is.
Ok...the fault you describe is caused by failure of IC001. This is a voltage regulator on the power board. You can identify the regulator as it is fixed to along thin metal strip near the middle of the board. It gets very hot during normal operation and will fail after a couple of years. The metal strip offers very little heat dissipation so the regulator operate in excess of its limits and therefore fails.
You need to take the lid off, remove the board which is mounted on the right hand side of the unit and replace the faulty regulator.
To remove the board, remove the fixing screw above the power connector on the back of the recorder, then the 4 fixing screws that secure the board. Next carefully remove the multi-connector that connects the board to other circuitry and lift the board clear.
A new regulator type STRG 6353 and can be obtained from several online suppliers. The old regulator can be removed by unscrewing the fixing screw, cuttiing the 5 pins with wire cutters. Then using a soldering iron, carefully removing the residual pins from the printed board making sure the print is not damaged.
Use some heatsink compound on the back of the new component, this will help it to dissipate heat more easily, use an additional heatsink if you can, which will help to prolong the life of the new regulator, then tightly secure it in position before carefully soldering the 5 pins.
Check that you have soldered it correctly without any shorted pins or tracks and reassemble the unit. I have repaired dozens of these successfully with exactly this fault.
Mains voltages can be lethal so always remove the power plug before doing any work like this and be sure of your own ability. If you're not confident in tackiling this, get someone to do it. Whatever you do, don't ditch the unit for such an easy to fix fault!
From your user name, I guess you're a radio amateur, so you should be on home territory.........
Hi, Just to confirm the problem of constant sefl check on my DMR-E95H DVD Recorder is the voltage regulator STR-G6353 on the power board, you have to remove the hard drive to get to the board on this unit, but its not a difficult job, bought part from NIKKO electronics, cost £6.33, get some heat sink compound as well to put between the heat sink and the new regulator, total time to do the job, approx 45 mins, recorder now works perfect and the advice on FIXYA saved me a lot of money, Thanx.

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... :(

Hook up the cable wire that comes directly from the wall to the dvd recorder's in connection, then get a 3 ft cable cord and connect from the out of the dvd recorder to the in on the tv. You should be able to set the dvd recorder channel and timer and leave it off. you then should be able to have your tv on and watch any station but to watch the tv with dvd recorder on, your tv should be set to either channel 3 or 4 depending on the switch on back of dvd recorder. I hope this solves your problem. Foxpaw13
You can try a factory reset (reboot).Here are the steps..
The following will set your recorder to the Factory defaults. (Will not format HD on DMRE80).
With power off (stand-by mode/CLOCK DISPLAY SHOWING):
1)Press and hold [skip reverse] [Time Slip] [Eject] buttons for about 10 sec 2)Display will show 'L1 TEST' 3)Now power off DURING TEST 4)Clock should be fashing 12:00 5)Turn power on and language menu will be displayed on TV
Use for DMRE50 DMRE55 DMRE85 For the DMRE75V press both [dub] buttons and [eject].
sorry to say but both of these sound like loader problems.ie the optics are faulty,you have to replace the full assy called a loader assy when this happens.Panasonic are the only company who offer part exchange tru authorised dealers.ie send back the faulty one and they will give reduced price on new one,.As to other makes see a lot of sonys with optic problems as well so isint just a panasonic problem.You could also try using ordinary dvdrs instead of ram discs as the optic has to work harder when recording and playing ram disc due to information contained.Hope I helped!
