Panasonic DMR-ES20 DVD Recorder Issue

Hi,

I have a Panasonic DVD recorder issue. When you plug it in (AC outlet),
the rolling "ooooooo" (initializing/recovery) never ends. I can force it to
go into standby by holding the Power button (on front panel) for 10 seconds.
Now there is a flashing "12:00". Next, I press the power button on unit or
remote, and a "Hello" appears. Normally, the "Hello" appears for a few
seconds, then goes away. Now, "Hello" stays on for hours. I did not wait to
see how many hours. Note: If I hold the power button for 10 seconds on the
unit, the display changes back to the flashing "12:00". However, I still can
NOT use this recorder.

PLEASE do NOT make suggestions because I have been there and
done that (years of electronics service repair background).

IMPORTANT:

I am looking for someone who had the EXACT SAME problem with
this model, "DMR-ES20" (NO letters after "20"), and he/she fixed
it. What did you do to fix this problem?

Thank You in advance, John

Yes. Bad capacitor. Replacing it fixed it.

Yes, but mine was still under guarantee from the local John Lewis
store. After the fix the service document said the remote control had
been replaced. I find that to be strange but I could see no evidence
of anything else being done.

Handy to know. I have a DMR-ES20 that I haven't used for a few years but I
did like it a lot and you never know...

I had some other DVD recorder, I found it in a recycling bin. It worked,
but got flakier. It used a standard 40pin connector, so I tried a
computer DVD drive, I think that worked, but didn't fix the problem.

So yes, given that I got an Acer 19" LCD monitor going by changing
electrolytics in the power supply (it sort of worked, but would reset and
I'd lose video then), I'm inclined to believe the DVD recorder needs new
electrolytics in the power supply. I've yet to pursue it because it's not
very useful now, the tuner doesn't receive DTV. But if it was still
useful, I'd have pursued the power supply.

Many years ago I had a somewhat similar problem with a similar Panasonic
DVD recorder (DMR-E55). It went into an endless checking cycle at switch
on. It was fixed by replacing the regulator chip (Sanken STRG6353),
which was stressed and operating at the limit of its specs with a
barely-sufficient heat sink. I also fitted a bigger heat sink.

Why might this be relevant despite your comment? Because the same fault
was known to affect other Panasonic DVD and HDD devices.

All of them done without component diagnosis?

Sounds like a processor code crash. Noisy power rails. Bad supply
decoupling.

Service manual should be about?

I really liked the way mine handled DVD-RAM. Being able to chase-record
(time-slip) with a DVD recorder was great, as was being able to part-erase a
disc.

I have an DMR-E30 with an issue very equal. You can switch it on and
nothing happens. It looks dead. But wenn you switch it of (10s
keypress) it write "BYE" in the Display. All Powerrails are fine.

I have a servicemanual and I know there is a maintanance mode. But it
did not work. So I realy believe there is something wrong in the
mainprocessor, because it can write "BYE" in the VFD, but it did not
change its behavier with maintanance jumper. Strange!

Sounds like a processor code crash. Noisy power rails. Bad supply
decoupling.

The old Panis are famous for a fault in the supply, especially of the
chip someone wrote before in this thread. Unfortunatly some have
bigger problems.

That is very sad, because the human interface device was much more
sophisticated than on my new 2000Euro TV with integrated recording
cabability. But fortunatly the TV program is so bad in these days that
recording is not necessary anymore.

Yes. Facebook is a little corny. Everyone switched to WeChat!

Medal?

I used Facebook when it first started and looked forward to it's
growth. After a few months nobody of interest to me started to use it.
My wife has loads of mystery "friends" on Facebook. She realised a few
weeks ago that they were trying to help sell something that was using
Facebook to market products. She has now been slowly removing people
but finding many become "friends" again. It's not so easy to remove
people using Facebook. She deserved a medal for persistence.

I asked the daughter of one of my staff what she did on Facebook for
hours every day. She mumbled something like "I must because everybody
else is using it".

OTOH the Usenet groups that are being used for marketing are easy to
delete, ignore or filter out.

I bet you be watch commercial TV channels.

So when you said "Some people don't use Facebook AT ALL. I'm one of them" it
was a lie. Got it.

I'll double down on that bet.

There is more than one capacitor in this unit.

WHICH CAPCACITOR?
