Power consumption on Standby

My old analogue TV used to consume 1 watt on standby, when standby had been
selected from the remote control. At such a low level, it wasn't worth
turning it off.

My new Sony ID TV (20S3000) states in its spec that it consumes 0.7 watts on
standby, but I've measured that it consumes 20 watts when standby has been
selected from the remote control; it only reduces to below 1 watt if you
switch the set off (ie using the button on the top of the TV). I asked Sony,
they simply responded specifically that it consumes 0.7 watts on standby
when it has been selected from the remote control.

I also checked a Philips ID TV. Its spec also said it consumes less than 1
watt when on standby. Again it consumes a little under 20 watts in this
condition, and drops below 1 watt only when it has been switched off by
using the button on the top.

Surely this is deliberate mis-information in the advertising. Both TV's have
a standby condition, which you may select from the remote control, and which
is specifically described in the handbook as "standby". Yet neither TV's
power consumption drops to the specified figure when in standby.

You become very power-conscious living on a boat and deriving all your power
from batteries

Nip the Tv and spec sheet down to your local Trading Standards dept. They
will double check your findings and quickly follow it up especialy as
'stanby power consumption' is so topical at the moment.

Have you tried setting it so it does not output the decoded digital
signal on the RF/AV output(s) and disabled automatic firmware upgrades?

Then ONLY way that what you have measured is likely to be correct (as Sony
won't be that far off!) is if there is some setting needed to make the
Freeview (IDTV) part of the set really power down fully in standby (and
not keep looking for updates)

How are you measuring the power?

That does sound wrong in orders of magnitude. If your measuring device
checks out correctly with a filament light bulb, then I'd wonder if
there is a fault with the TV you have.

I can't read ... OK, faults with two TV's - or more likely your tester.
What is it?

An incandescent light bulb is a resistive load, a TV won't be.

Alan - After you have gone into standby with the remote control, you
will find that the power will drop to 1W after about five minutes. I am
given to understand that the set checks for updates first when it's gone
into standby. After completing various checks the power then drops to
within spec.

If the measuring device doesn't apply power factor correction, 20 watts
is a bit of an over read, I think? Hence my use of the word 'magnitude'

There probably is something else wrong with it.
