Philips' Eco TV sips power, saves rainforest
The 42PFL5630D uses less power than any 42-inch LCD we've seen.
(Credit: Philips)At CNET, we take HDTV power consumption seriously, which helps explain our excitement when Philips announced its Eco TV. The 42-inch, 1080p resolution, flat-panel LCD, model 42PFL5603D (due in March, $1,399 MSRP), is packed with power-saving features.
Watch the Philips 42PFL5603D Eco TV video on CNET TV.
Chief among them is the ability to dim the backlight--by up to five times peak brightness--in response to program material, much like the "local dimming" found on Samsung's LED-based LN-T4681F. Dimming the backlight in darker scenes has the dual benefit of saving power and improving black-level performance, according to the company. The backlight can also be dimmed via a room lighting sensor, so in dark rooms it will use less power. There's also traditional a "power-saving" mode that caps the peak light output. All of these features can be turned on or off at the viewer's discretion, which should please videophiles since many of these features' potential effects, such as black-level fluctuation, could negatively impact home theater image quality.
With this trifecta engaged, we saw the panel's power consumption dip to an impressive 75 watts during the in-booth demo--Philips had hooked up a Watt's Up to track consumption. That's a bit more than a standard incandescent light bulb and 30 watts less than the most miserly 42-inch LCD we've tested ourselves so far, Philips' own 42FL7432D measured after calibration (more info). The Eco TV's standby power is also less than 0.15 watt according to the company, also among the best we've seen.
Until we test it over a period of time we have no idea how much money this HDTV will save on your annual power bill--the dimming backlight introduces too many variables--but we don't expect it to be more than $50 over a standard 42-inch LCD, assuming average energy costs. Philips also built in a few other non-power-related greenie features, including lead-free materials and only "trace" amounts of mercury, which enables it to comply with strict ROHS and State of Vermont standards, respectively. And yes, even the box is made from recycled material.
The 42PFL5630D lacks the company's patented Ambilight technology, which is actually another power-saving perk since those lights draw more juice. It also lacks the high-end features such as the 120Hz technology found on its more-expensive brethren--this is strictly a mass-market TV, and one that should be more satisfying to environmentalists than any large-screen flat-panel we've seen so far.

I would love to have one in my room. That would be the best.
That said, I have yet to see an HDTV, lacking 120Hz processing that handles "judder" (particularly during fast motion scenes) well enough for me to invest the money.
For energy efficiency, deep black levels (1,000,000 to 1 contrast ratio!) and smooth motion it sounds like OLED TVs may be the way to go... Hmmm, how long until they're affordable, I wonder!
I think the manufacturers are missing what the consumers are demanding in the newer TV products. Hopefully also it will have about 4 HDMI ports. A DVI port for computer hookup would be nice too.
My understand is that there is some newer technology coming out to eliminate the cable box, but I havent seen alot of details about that yet.

- It's surely not about 'saving the rainforests' any more, it's about saving the whole damn planet, or rather, the human race (including those living in the USA!), since the planet, and nature, will survive whatever we do to mess things up.
