My Panasonic TV TX-P46G10B consumes approx 30W on standby but the manual
states it should be 0.4W (without monitor out recording).
What is 'monitor out recording' and how can it be disabled? There is no
reference to this in the manual.
Same comments apply to my other TV Panasonic TX-L32D26BA.

I have submitted this question to Panasonic Support but (so far) have
received no response!

According to Google, the full power down is delayed by a few minutes.
How long did you wait?

According to Google, you disable this by not setting any recording timers.

Maybe they got the decimal point in the wrong place in the manual?

Yes, some receivers stay active for 5 to 10 mins extra, to perform
housekeeping and also look for any new services, or software updates.

Leave it 15 mins, then measure.

Thank you David for your input, which triggered me to investigate further.

There is indeed a time delay. After powering down to STANDBY the power
consumption drops to 16W then, 4 minutes later, drops to less than 1W. This
applies to both Panasonic TVs.

What did you Google to get this info?

I don't know about your particular model, but my 3-years-old Panasonic
has a much greater "standby" consumption than is stated in the manual.
This is because it regularly turns itself on (silently) to check for
updates. As you have noticed, this consumes a lot more power. In true
standby the consumption is only 0.3W, but it most certainly is not as
low as that in "check for updates" mode.

What I have not been able to find out is how often it does this.
However, it is not just soon after turning it off that I notice clicks
from the internal relay(s) which I assume are changes to the power it is
using.

Fitting an energy meter between the set and the power supply, and
checking it when the TV is in standby" mode, will give you a better idea
of the true power consumption over time. Note, however, that energy
meters may give misleading readings where switched-mode power supplies
are concerned.

Mine makes a discernable "click" when it switches down to low power standby mode. My sisters boyfriend (a professor in the field of climate change) was seemingly amazed that devices did in fact power down to such low levels of power usage. I think he rather naively assumed that the newspaper reports of TVs using as much power in standby as they do when turned was factually true!

Beards and sandals didn't seem to do the Roman emperors from Hadrian

At times, the level of so-called debate in this ng really is
desperately childish.

Newspaper reports tend to confuse power with energy.

Quick definition: power is the rate of using energy.

Electrical power is measured in watts or kilowatts and energy in watt
hours or kilowatt hours. (The "units" of consumption measured by
electricity meters in homes, etc. are kilowatt hours.)

If a TV uses 1 watt when in standby and 23 watts when on, and is on for
one hour each day, it will consume 23 watt hours per day in standby and
23 watt hours per day when on. So it will consume the same amount *each
day* when in standby as it does *each day* when on.

If that TV is used for only half an hour each day the ratio gets
"worse". It will consume 23.5 watt hours in standby and only 11.5 watt
hours when on. So in standby it will consume slightly more than double
the amount used when on each day. Of course the total consumption will
be only 35 watt hours compared with the 46 watt hours total when used
for an hour each day.

Who cares a monkey's bollock? These amounts are minuscule compared to
the power used in industry. The greenies attack domestic use because
it's a soft target, and because they can work on the idiotic guilt of
simple minded middle class females.

Why choose made-up numbers to illustrate your point?

The average "on" power for the set is rated as 207W, so it can remain in
standby for over 21 DAYS for the same energy cost as 1 hour of viewing,
rather than remaining in standby for 23 HOURS as you suggest.

Because I was too lazy to look for actual figures, and I wanted figures
that did not involve fractions from the get-go. I was just trying to
illustrate a principle. That's all.

and they pay a fraction of the residential rate, so we're subsidising
wasteful industry.

Some office blocks don't have switches for each floor to switch off their
lights!

From what I see, it must be you who is confused, as the post you

Yes I think the explanation makes absolute sense. It is rather alarming that
the TV uses more energy *per day* in standby rather than in use, but it is
true, nevertheless.

It doesn't help that electricity meters read in units of watt-hours, because
most people see "watt" and assume it is a power that is being talked about.
If meters registered in joules or kilojoules (multiply kWhr by 3.6 to give
kJ) then there wouldn't be the misleading (to non-scientists) "watt" in what
(*) is actually a measurement of energy.


(*) I *knew* the watt/what confusion would (unintentionally) rear its ugly
head sooner of later :-)

It's slightly worse if anything, as each day the TV will turn itself on
at 3am to check for updates. If there aren't any, it will go back into
standby, but if there are, it will partially "wake up" to download them.
It won't use much energy as the screen remains dark, but it is an
additional load.

In any case, even if a TV uses 25 watt-hours a day, it will take 40 days
to use 1 kWh, which costs about 10p.

Big deal!

Yes! My rule of thumb is that it costs about £1 per watt-year. I.e.
something that consumes one watt will cost about £1/year to run. It's
probably a bit more than that now but it gives a ball-park figure at
least.

Has this argument really been going on since 2012?
Anyway, my old Goodmans box seems to run just as warm in standby as when
its actually running. In theory, if devices were really efficient they
should not waste power heating stuff up.
