    samsung or other major brand; go with 240 hz for smoother action picture. You should be able to go to Costco and find an excellent one for $600 to $750 or so. If you have their American Express card, the warranty is extended to three years no charge.

    I had a 27" TV and thought a 42" LCD would be too big. Wrong... I then bought a 55" LED and all is well. Do get the LCD and I got a 480 refresh rate. PM me your pnone number and I will tell you a couple of things if you want to know them. Ray

    Print this articleWhen shopping for a new TV, you may come across some models categorized as edge-lit LED, while many others are simply labeled LCD. While edge-lit, light-emitting diode TVs and liquid-crystal display TVs are different, they both still fit into the same category of TVs known simply as LCD.

    How to Make Edge-Lit LED Signs Comparison of an LED TV to an LCD TV LED Vs. LCD
    LED TVs are not a new type of TV technology. Their primary difference from a standard LCD TV is in the way that the back light on the TV works. With a regular LCD TV, a cathode fluorescent light creates the light that the TV uses. With an LED screen, the light is created by light-emitting diodes instead of a fluorescent light source. The rest of the TV is basically the same.

    Edge-Lit Vs. Back Lighting
    LED televisions can fall into one of two categories: edge-lit and back-lit. With an LED that has back lighting, also known as full-array back lighting, the lighting for the TV comes from the entire back of the screen. By comparison, with an edge-lit LED TV, the light comes from the sides. The manufacturers simply put LED lights on all four sides of the TV and then the light is shined back towards the middle. The light is then guided back across the screen.

    The primary advantage that edge-lit LED televisions have over traditional LCD screens is that they can be much thinner. When an edge-lit television is made, it does not need a separate layer of lighting across the entire back of the screen. Instead, the manufacturer can put the LEDs on the side of the screen, which saves a lot of space. By comparison, with a traditional LCD, the TV must be thicker and it may not be as suitable for mounting on a wall.

    Picture Quality
    Consider the difference in the quality of the picture on edge-let sets and other models. Standard LCD sets and most edge-lit LED televisions lack "local dimming." This feature of LED sets with full-array lighting can make colors "appear to pop," says the website CNET Reviews.
