How do you turn a normal tv into HDTV?

Standard definition TV's really can't be changed into anything other than what they are. In other words, there's no conversion kits, etc. But a standard definition TV can still use the digital HDTV signals with the use of a converter box on your antenna system, Dish or DirectTV RF output jacks, etc. The picture, even though converted, will still generally look better than a standard analog signal just because there's quite a bit more information in the signal allowing your analog TV to wowrk at it's maximum capabilities.

I have insignia ns-27lcdi am having problem with my tv when i turn it on it turns on the red sign of power turns blue but screen stays black and no picture or sound and i can't do anything?

It sounds like your set is looking for an input device. If you have cable/satellite, be sure (from the menu) that you have it set for cable(same as satellite) or AIR, if you're using an antenna. The blue light sounds like the input source is set for video(dvd), games, or Video tape.

What are the reasons behind the success of 3D and which TV is the better 3D active or passive and why?

The success of 3D television is not yet fully demonstrated. It is still an emerging technology and observers have yet to confirm that it is indeed successful. However, consumers are buying 3D models because it represents the next step forward in television technology and no doubt will continue to do so.

The choice between active and passive is subjective. Active systems use a full resolution frame and cuts the image rapidly between the left and right eye. Some viewers report that they notice flickering with this system. Others do not see any flicker and it depends largely on the model and manufacturer. Passive systems split the screen into alternate lines so each eye sees only half of the total number of lines. The resolution is effectively reduced to 540 lines (compare this against the 480 or 576 lines of standard definition television). The problem of flicker is avoided at the expense of the lower resolution.

So, which is best? That is a matter of opinion and the only way to decide is to see both technologies and decide which offers the best image and most comfortable viewing.

Can you use glass cleaner on a flat screen tv?

Most likely will not hurt it. HOWEVER, it is possible for it to destroy it. Check the bottle and television manufacturers instructions for specifics. Usually a microfiber cloth is the correct action.

Can anyone explain to you 120hz tv?

Television images are created with a stream of still images. In the US, the stream is 60 fields each second. As two fields are needed to make a complete frame or image, the frame rate is 30 per second. In Europe, the rate is slightly slower, at 50 fields and 25 frames per second. As 30 or 25 frames per second is fairly slow, there can be a noticeable flicker and movement can look jerky as well. This is more of a problem in Europe than the US because of the slower frame rate in Europe. The frame rates were chosen years back according the mains supply frequency in the US and UK. Although this is no longer of any concern, with advances in elecctronics, the frame rates have stuck. Even with the move to high definition, the frame rates remain the same - 60Hz in the US and 50Hz in Europe. All other countries, by the way, follow one of the two frame rates. The 120Hz or 100Hz displays aim to overcome the flickering and jerky movement by inserting a new field between each of the fields received by the television. The theory is that with 100 or 120 fields being displayed each second, the human eye cannot discern the discrete images and see only a smooth picture. For static and slow moving images, the theory works well but as with all engineering solutions, this isn't a perfect one in all cases... Each field that is inserted needs to be made up. It cannot be a copy of the previous field because it would result in two identical fields, returning the output to 60 or 50 Hz. So, the new, intermediate field has to be calculated by taking the previous and the following field and working out what the image would be, if there was an original field at that time. It's a process called temporal interpolation and needs a huge amount of processing power. Sometimes, the calculations to generate the new field can get confused and the result is a disturbing judder in some parts of the image. Broadcasters who have to use similar techniques will spend a great deal of money to get the best conversions and domestic televisions will never have the same level of hardware installed. These errors are rarely visible, but before spending a lot of extra cash on a 120Hz television, spend some time looking at the image. Look for fast pans across football supporters as the camera follows the ball, for example. Also look at fast scrolling text. These are the images that may cause problems. If you are happy with the image you see and it looks smoother than the 60Hz equivalent model, then it's a good buy. If it doesn't look smoother, you should ask yourself if the extra cost of a 120Hz television is worthwhile. That said, there are many 100 and 120Hz televisions that do a good job. Just make sure you can see the improvement before you splash the cash.

Can you get teletext on new digital or HD Flatscreen tv's?

In the US it's called captioning and it is required that all sets with screens over a certain size have this feature built in. Go into your VIDEO MENU and look for CLOSED CAPTION or just CC. You have to be watching a program that has captioning on it.

What does the contrast ratio on widescreen TVs mean?

The contrast ratio is a measurement of the range of brightness can display. Theoretically, the higher the number, the better the image. A high contrast ratio means that whites will be brighter and blacks will be blacker than a lower contrast ratio. It has become an important feature because early LCD and plasma screens had a very poor contrast ratio compared to the older CRT televisions. Modern displays have largely overcome the problem and ratios of 5000 : 1 or more are quite common. However, a high contrast ratio doesn't always indicate how well the screen will display dark grays and near whites. Therefore, the real test is to look at the screen to see how the image looks. A good screen will show lots of detail in dark areas and light areas. A poor one will tend to show less detail and dark areas may show up as blacks rather than a range of grays. To make it very simple, if the picture looks good, then it is good, regardless of the published performance data.

Normal gameplay shouldn't damage your TV, unless you leave the game paused with a static image on the screen for a long time.

If you need to pause the game for a long time, turn the TV off.
