Paging Mena661

What make and model LCD TV is it that you are using that draws 2 amps?

Thanking you in advance.
  • The LED 32inch LG we have has one ( LG32L3400-UA)

    I took some readings for the various brightness settings using the inverter and got:

    Intelligent Sensor-25w ( you sit in the dark to get the low watts, but that means less amps draw from lighting too :) )
    Vivid-65w (8.2a on Trimetric)
    Standard-50w (7.4a)
    Cinema-35w (6.0a)
    Sport-65w
    Game-45w

    The 32inch Samsung LCD was
    Dynamic 120w
    Standard 80w
    Movie-70w
  • Burb, look at the TV's I mentioned. They should have that feature.

    I didn't know any flat screen TVs had such a thing, good info. I have a new 24" Insignia (Best Buy) TV in the bedroom that specs the power draw at 40W, which is about 3.3A at 12V. You can reduce power consumption by decreasing the backlighting and brightness in the setup menus, but it would really be nice if it had a sensor that did it automatically based on ambient light.

    I am looking for a new TV for the LR also, probably in the 32" range, please post back if you find one with a light sensor.
  • Unfortunately, they don't make it anymore but it was a Vizio E261VA. The advertised power draw was 33.8W but that was only when it was first powered on. It dropped considerably after that. It's LED backlit and has an ambient light sensor. I would look at the 2014 Vizio E-series line up and see what they have as a replacement. Be careful though because on Vizio's site and other sites they tend to mix the 2013 and 2014 lines together. You can tell the 2014's from other years because there will be a -B# (# = number) in their model names. For example: a 2014 70" E-series would have the model number E700i-B3. It MUST have a B for it to be a 2014. I have been looking at the new one's and there are 23", 24" and 28" TV's with an advertised 22.77W, 25.7W and 25.8W power draw. Even the 32" has an advertised draw of 32W. You can get the smart or non-smart versions, doesn't matter on draw. Make sure the unit you buy has an ambient light sensor. That's the key to the low draws.

    These will all draw less than ANY cheap ass 12V TV that so many like to promote here as being low power and efficient. Even when run through an inverter. I have yet to have anyone here on the forum get lower than my Vizio and its 20W draw.
