Customer Review: Most satisfied
I needed a new TV that would fit in a cabinet in my house. With the thin bezel, I was able to maximize screen size for this space with this 40" model. I am most impressed with the picture quality, even during the daytime as the family room has a window wall and is bright. I had seen this model at various Houston stores but Amazon.com had the best price and saved enough to pay for the extended warranty.
Customer Review: LT-40148
1. Delivered carefully and in excellent condition. 2. Plugged it in and it lit right up 3. Has an instant on and warm up mode (saves electricity) 4. Wide range of inputs - my son has a Sony Bravia with one HDMI port. This has four. I have a high definition video DVD player into one HDMI and Verizon FIOS in the other. The TV recognizes the inputs so to address them, click "input" and it flip flops back and forth. 5. Speakers are OK. I have bypassed them using 2 big AMT 5 stereo speakers with Heil air motion transformers, center speaker, sub-woofer and two back speakers. The amplifier (big Sony) takes in the digital audio and sends out true DTS, 5.1 etc. With the TV and sound - t is better than going to the ball game or the movies. 6. My FIOS remote covers all the functions of the TV remote except for menu setups - fairly standard programming codes. I forgot the exact code. 7. I removed a 32" tv (150 lbs) and it took two of us to do it. I put this one in by myself. It has a very thin frame and can fit into many of the entertainment centers. The new 40" Bravia XBRs are just 1" wider. 8. The picture in HD is unbelievable. You can see individual windows in panoramic views of cities - faces on people in stadiums. 9. Price/performance? I prefer this over my son's Bravia. The new XBR ($2200) may be better than his older one. This was only $1600.

What does LCD TV mean and how does it function? LCD stands for liquid crystal display. Behind the screen are a number of pixels followed by a fluorescent light. When this light falls on the pixels, an electric current is generated, creating light variations, which make up the vividly colored images that we see. Generally, the twisted nematic liquid crystal is used which has a naturally twisted crystalline structure.

The screen size of an LCD TV varies between 13-46 inches and it is about 2 inches deep in thickness. They are very light and so extremely easy to install. This indicates that they require very little space and come with a very sleek look. In fact, they can very well be compared to the fragile beauty of a woman!

Next is the consideration of the 'burn-in' factor. LCD TVs are not susceptible to 'ghosting' which results due to premature dying out of the pixels. The uniquely twisted crystals do not allow 'burn-in' or 'ghosting' to happen.

There has been a marked improvement in the refresh rate or response time of LCD TVs. Previously, the images tended to lag behind and stay on screen for a period of time that was much more than necessary. Recent technological advances have put all that behind. Usually, the response time varies with the size and quality of the LCD TVs.

The contrast ratio in the more advanced LCD TVs is 1000:1. The contrast ratio is measured by the ratio between the brightest white to the darkest black. The scenario has improved here too. Research is on to push the ratio well past the 1000:1 mark.

Sixty-thousands hours is the average life span of an LCD TV. So at an average viewing of 8 hours a day, an LCD TV should last for about 20 years. The life span of an LCD TV is dependent on the back-light. Since it uses a liquid crystal, there is nothing else which can wear out other than the back-light. Technology has found a way around this problem by creating replaceable back-lights as well.

Power consumption, which is perhaps a very important aspect, has a definite advantage in case of LCD TVs. LCD TVs utilize fluorescent back-lighting and so power consumption is low and steady.

LCD TVs are unaffected by changes in air pressure. This makes it a favorite among air travelers. The performance is consistent and the picture flawless, regardless of the altitude of the airplane.

There is much talk about mercury being used for the fluorescent lighting. But, the manufacturers will vouch-safe for the fact that a nominal amount of mercury is used. This mercury does not come in contact with the viewer and so is entirely harmless.

Some manufacturers are trying to incorporate picture-in-picture feature in their monitors. This feature enables a viewer to see one program on the full TV screen while a few other programs can run in small windows in it. The viewer gets the added advantage to watch a particular program, while waiting for the intermittent advertisements to end in another window.

Experiments are on to extend color reproductions in LCD TVs. The idea is to use two back-lights with slightly differing intensities of colors in consecutive frames. This will enable the viewer to experience a better and a more vivid picture using a more precise color variation.

An LCD TV is a whole new experience, the flavor of which can be savored only by purchasing one. The advantages are manifold and the experience is just exotic. Indulging in one is a worthy bargain.
