led tv keeps blacking out image
Anthony
I always hear about these great deals on LED and plasma TV's on Black Friday. 47" TV's go for $300, etc. I was never one of the people to go out at midnight on Black Friday. However, I've been hearing online is starting to carry the same sales that are in the store, except online. I've never had much luck on Cyber Monday.
Does anyone have any luck buying TV's or electronics online on Black Friday? Are there generally a lot in stock online or will you need to be the first one logged on at midnight?
I'm looking for a big screen LED TV and I'm debating waiting until Black Friday to buy it, however, if I hear that it's difficult to obtain one, I'll just buy one in the next few weeks.
Thanks guys!

One problem is that you may find a lot of lower end flat screens for sale at very low prices and if you wish to use a comp to link to the TV or to play or use video consoles on the TV it might not refresh or have the correct fast action movement responses.If you're looking for just something to watch TV then many of the low end make/models will be fine.
For example they sell a low end make called Sigmac stores have sold thousands of the 42 INCH TV's and most customers are happy with the product bec they mostly wanted a big screen flat screen TV and they claim it suited their needs.The same model won't play fast action movements very well unless you know how to adjust all the comp video card, TV or game console settings up properly according to the different file formats or games etc.
What I've found is here in Canada Black Fri sales seem to be the best prices according to Xmas and Boxing Day sales etc.I've seen Walmarts for example offer a 32 inch RCA for 168-180 bucks but you have to be at the store way before they open and then you'll be asked what items you may wish to buy and then be given a slip that is for say the TV you want.This means they might only have 10-20 of these models in stock and as little as one of another TV that is on sale for some great price of 500 bucks etc.Now online the main warehouse may have a lot more in stock but of course first customers to place their orders will get the best results.I've also seen free shipping offered especially if you live in the United States and are ordering from a USA site.
Personally what I'd recommend is that you make up a list of all you want to use the new TV for and then figure out if the specs of the TV's you might wish to buy. List and compare and the different makes/models features, ports and over all specs. For example you may wish to have a fast refresh rate and some models will only be 60hz and others will offer 60-120-160hzs settings or different ranges of it's Hz capabilities.The resolution capabilities are also vital so you need to keep that in mind and some might offer resolutions of 1920 x 1080p.Even the Contrast Ratio can be misleading bec it may indicate 2,000,000:1 ratio but the true quality of the TV might not match up.Next you'd have to consider the Response Time and it should be that the lower the number indicated the better Response Time.A feature that is related to this is Game mode etc of a TV.
Hope that helps and best of luck.By the way I'd suggest to look on different sites and in the stores to see what makes/models are sold that are within 20-40% over your current budget and then compare the specs and customer reviews to decide which TV's you may be truly desiring to buy.Samsung, LG,Panasonic Toshiba are all good makes but you have to also consider that every make has different models and some models are just too expensive or they are great for the suited purpose and some work great that are in fact in the lowest model price ranges.Note if you can wait then I bet you'll save some cash bec prices to drop on many Makes/models/items during the up-coming Black Fri sales etc.

What's the difference between plasma and LCD TVs these days?
circusmort
I've noticed a few more plasma TVs showing up for sale in stores - considerably cheaper than LCDs of equivalent size and features, so what's the catch?
Answer
After all, there are so many acronyms and buzzwords to wrap your head around, such as 1080p, 120/240Hz, 24p, HDMI and LED backlighting. Huh?
Along with deciding how big a screen you want (which is usually tied to the size of your budget and the dimensions of your room), the next choice should be between LCD.LCD (LED Backlit) or Plasma â and all have their merits. Here, we'll describe each of these formats, and also point out their shortcomings.
LCD
What is it?
lcd tv 120mhzSimilar to your laptop computer's monitor, flat-panel LCD televisions use a liquid crystal display to produce a sharp and bright picture; these crystals are sandwiched between two panes of polarized glass, which are stimulated by an electric current and illuminated by fluorescent tubes housed behind the glass. Some newer LCD TVs, however, use LED-backlighting instead. LEDs, or light-emitting diodes, translate to a better-looking picture (see photo).
Pros
There are a number of advantages to buying a LCD televisions. For one, with more than three-quarters of all televisions embracing this technology, there is a lot of choice when it comes to manufacturers, models and sizes (13- to 103-inches, in fact). Competition, of course, breeds more aggressive pricing, too, which is good news for the consumer.
Flat-panel LCD televisions are also very thin, light and energy efficient, and are ideal for rooms with plenty of ambient light, which, for example, comes through large windows as they tend to absorb rather than reflect light (reflected light can obscure your view of the screen).
Cons
Until recently, LCD TVs didn't handle fast motion images as well as plasma TVs, resulting in a somewhat blurred image. Newer LCD TVs, though, have added technologies such as 120Hz frame doubling (or 240Hz frame quadrupling) to smooth out motion. It's still not as good as plasma, but much better than before. Also, LCD TVs used to have problems showing dark blacks (because a light was still on behind the pixel showing black, resulting in a more greyish hue). Many LCD televisions today use local-dimming with LED-backlighting (see next section) for improved contrast ratios (whiter whites and blacker blacks) - but, keep in mind, this is not an issue associated with plasma TVs.
LCD (LED Backlit)
What is it? Not a Different Type of TV
led lcd tv backlighting backlitItâs tempting to think LEDs belong in a completely separate category beside LCD and plasma TVs, but in reality, an LED television is just a type of LCD TV. The proper term would really be "LED-backlit LCD TV," but that always seems to get truncated to "LED TV" in everyday conversation, perpetuating the confusion.
To understand how LEDs function in an LCD TV, think of an actual liquid-crystal panel as the plastic pegs in a Lite Brite. They hold a translucent image, but without a powerful backlight to punch through and light it up like a signboard, youâre not going to see much. On your old Lite Bright, an inefficient incandescent light did the job, but pretty unevenly. On a typical LCD TV, fluorescent lights provide the backlighting through a special plastic sheet called a light guide that distributes light from a fluorescent tube evenly over the surface of the TV. On an LED-backlit TV, fluorescent tubes are replaced with light-emitting diodes â LEDs â the same technology that probably lights up your digital watch, the buttons on your monitor, and the indicators on your stereo. They can be either situated along the edges of the TV like a fluorescent tube, or arranged directly behind the screen in a grid. But what difference does it make, and why would anyone spend so much money on it?
The Benefit of LEDs
The most obvious reason LEDs have fallen into favor in LCD TVs: theyâre simply more efficient. Although fluorescent lights do a decent job converting electricity to light in the big scale of things, LEDs perform even better. Typically, manufacturers claim an efficiency improvement of up to 30 percent over fluorescent-based sets, which can add up significantly over the lifetime of a TV, especially on larger screens that use more juice to begin with.
LEDs are also much smaller than tubes, even after accounting for the number of them needed to light an entire TV. That means LED-backlit televisions can be manufactured significantly thinner than their tube cousins. For instance, most of the ultra-thin televisions that measured under an inch thick at CES used LED backlights, because they add very little depth to the profile. Though commercial variants arenât quite as dramatically thin as these prototypes, theyâre significantly skinnier than their fluorescent-backlit counterparts, making them some of the most chic and living-room-friendly HDTVs out there.
For home theater enthusiasts, LEDs only matter for one reason: image quality. Because fluorescent tubes must light the entire screen evenly, designers have no way to vary the backlighting intensity in different parts of the
