Earth Notes: A Note On an Energy-Saving Replacement TV

How can we save energy while glued to the goggle-box?

Bigger and Better (and more Frugal)

As of 2011/09 my partner's 13" Sony Trinitron CRT TV must be about 20 years old; still working but she'd like a new one and I'd like the opportunity to trim some of its power consumption, about 0.5kWh a day typically, or about 70W including the small separate SCART/UHF converter for the DVD player.

We don't have a huge living room, so 22" or 24" should be plenty large enough, and with an LED-backlit LCD model then power consumption ~50% lower than the CRT seems to be possible, and a well-integrated DVD would reduce clutter and could remove another small parasitic standby draw.

We wouldn't chuck the working TV, just maybe wheel it into the kitchen with the existing DVD player, so we'd have to avoid the Jevons/rebound effect, ie the temptation to watch TV more often negating potential energy savings.

As of 2011/09/15 I had the following list of possibles plucked mainly from the Argos catalogue (* for integrated DVD player):

Size	Price £	Argos Cat#	Brand	Model / EAN	Consumption In Use / Standby	Comment
22"*	199.99	529/6101	Hitachi	L22DG07 / 4902530910032	40W/1W	EST recommended
22"*	159.99	529/6149	Bush	SuperSlim 22 Inch / 5060234040871	???/1W
22"*		529/5353	Bush	LED22916DVDFHD	???/1W	EST recommended
22"	149.99	529/8518	Sharp	LC22LE22E / 4974019664149	20.3W/0.43W	Argos lists power consumption as 24.6W/0.21W
22"*	184	-	Sanyo	LCE22FD40DV-B / 4994334288172	45W/0.5W	From Sust-it.net and manufacturer's site, though note that PDF on manufacturer's site says 45W in use and was confirmed by customer service 2011/09/19: We referred your enquiry to the Product Manager for televisions and he has advised that the power consumption is 45 Watts when the power is on. Our website will be corrected and meanwhile we thank you for drawing the matter to our attention. And in a follow-up 2011/09/23 Sanyo confirmed that it has no 22"--26" LED-backlit LCD TVs available in the UK with or without built-in DVDs with in-use consumption well below 45W.
24"*	179.99	529/8130	Bush	-	36W/0.3W
24"	159.99	529/8123	Bush	24LED1024	32W/0.3W
24"	189.99	529/8491	Sharp	Sharp LC24LE210E	25W/0.25W

Note that a new separate DVD such as the Sony DVPSR750 (Argos 936/8530) should cost ~£40--£50 and consume 6W in use, 0.5W standby.

The Sanyo LCE22FD40DV-B, available via Amazon / Southern Electric for £184.37 as of 2011/09/16 looks very tempting.
