Panasonic DMR-EX75EB: Forgets the time
 

Panasonic DMR-EX75EB

I have had this recorder for several years. I switch it off at the mains
every night, and until a few days ago it has worked perfectly.

Now, however, when I switch it on at the mains, I find that it has lost
the time and all the program settings. I now have to reset the
clock/calendar and rescan before I can use the machine.

I wondered if there was an internal backup battery in the recorder that
had run down (like in PCs), but looking through the Operating
Instructions manual I cannot find any mention of a backup battery.

So what do I do now?

It's a recording machine for making unattended recordings, and as such it
is designed to be left powered all the time. Why are you surprised that it
doesn't work properly when not used as intended?

No, of course, due to the ubiquitous "No User-Serviceable Parts Inside"
business.

I'd open it up and take a look anyway. Nothing to lose.

Don't switch it off then.

No, because they don't want Joe Public poking about inside.

Take the lid off and have a look. Of course, this is the one time you
should switch it off!

The manual for the DMR-EX75EB says on page 19 (bottom):

"If the unit is disconnected from the AC mains, all programme data are lost"

I think his point was that it used to get the time and retain it and its
channels. This does all seem very peculiar. I'd have thought that it would
have had flash ram for programs times for recording etc, but could well lose
the time.

That does seem a bit annoying, as there are often power cuts and one would
have thought it could retain info, I mean my old Sony Betamax can still
retain the programming through a nights power cut.

If it's worked before but doesn't now, it could be as you say, the
backup battery. You have nothing to lose opening it up and having a look
around. The backup battery should be fairly obvious. If it's not a
button cell, it could be some kind of package with red and black wires
plugged into the main board. If it's the latter, it may be more
difficult. I suspect it'll be a button cell and only cost a couple of
quid to replace.

That's referring to the guide.

I suggest opening it up and having a look. It must be long out of
warranty, so it won't void it.
