Samsung LN46B640 46″ 1080p LCD HDTV

Power consumption is certainly something I consider when purchasing any new consumer electronics. The last thing I really want is to purchase a TV that continually drains my wallet with a power guzzling 600W usage. The advancements of technology has allowed us to enjoy the benefits of high definition pictures without expensive monthly bills. To test the power draw on the 46B640, I will consider the case of the TV being powered off to monitor the phantom load and watching basic TV.

Samsung 46B640

The Samsung 46B640 carries a phantom load of 2W; this means that even with the TV turned off it still draws 2 watts of power from the wall. The only way to eliminate this power usage is to unplug the TV from the wall. The operational load hovers at a reasonable 212W. The power load starts off at 230W and climbs to 245W for a few minutes before dropping and hovering at the 212W level. The increase and drop is likely related to warming up the screen.

When I press the “ON” button for my TV, I’m use to instantaneous start-up but what I found out with the B640 is that is very slow to power up. I would click on the “ON” button and it felt like 5 seconds will pass before the first sign of life would appear on the screen. I consulted Samsung QA Lab and confirmed this was not an issue with my TV but all of them. It’s simple a matter of the TV going through its boot sequence. It’s slow and I find it annoying. I hope this issue can be resolved through a firmware update or hardware modification.

  2. Just hope that more channels could start broadcast in HD. But it’s probably quite expensive to buy all the new equipment needed.

  3. Don’t think we can get the LN46B640 in the UK. This looks like the nearest version to it: http://www.buydigital.tv/Product-show.asp?BigClass_Id=11&SmallClass_Id=300.

  4. Nice review. I just purchased a 640 for the USB. However, mine does not produce sound when playing avi or mp4 from USB. How did you generate the avi file in the first place? Thanks!

  6. Would you happen to know what’s the spece between the bottom of the TV and the stand? I am wondering if the receiver can fit in this space. I bought that TV, it wasn’t delivered yet, but don’t know if the receiver can fit between the TV and the stand. Thanks for a response.

    Off the top of my head I can’t remember but it would only be in the range of 1.5″ or so

  10. hatsukitemo, terftigtewheat:

    You can connect your computer/notebook to the TV with any VGA cable or HDMI cable, depending on what outputs your computer/notebook has. You will also need to connect audio out from your notebook/computer using a 2.5mm to RCA.

    Enjoy!

  12. I purchased a Samsung 640 series TV about 8 monthes ago and it is by far the best TV I’ve ever owned. There is one thing about it that concerns me. Two or three times a week I come home and find the Tv “partially on”. The TV has a blueish grey glow and the back of the cabinet is warm. When I left the house the screen was off and completely black. My concern is that the Tv will wear out prematurely. Is there anything I can do to prevent this from happening?
