The three main high definition television types are LCD, Plasma, and DLP. Each type has its own advantages and disadvantages. The average consumer is concerned about price, quality, size, and lifespan. This post will hopefully answer some basic questions about which type is best for what situation.
LCD
Liquid Crystal Displays (LCD) are commonly found as laptop and computer flat screens. In recent years the technology has changed to allow them to be manufactured much larger. The advantages of a LCD TV are that they are very thin, usually around 4 inches or less for a 40”. They are lighter than a Plasma TV and produce less heat than both Plasmas and DLPs. The life time of these units is very long, you don’t get burn in or picture fading over time. The picture quality is also top of the line, they are able to display any formats available today, including the new 1080 progressive (double high definition). Some disadvantages of LCDs are that the price is higher than other types and there maximum size is currently less than 60”, and the price for the larger displays are usually double what the price of the next size down is, however the price is defiantly on the way down.
Plasma
Plasma TV’s are the televisions that got everyone interested in having a flat TV hanging on their wall. But now with the size of LCD TVs increasing and the price decreasing, Plasma TVs are becoming more extinct. The problems with them is that they produce more heat and weigh more than LCDs. They also have a half life of 60,000 hours; this means that the more it is used, the more the picture fades. They are also more likely to get burn it, this is that when the same picture is displayed, when it is changed you can still see the outline of it. The best reason to purchase a Plasma TV now is that you can get a very large screen for a very good price!
DLP
DLPs are a much different technology. They can rarely be hung on a wall because they usually larger than 8 inches deep, commonly around 14 inches. However, DLPs are a great choice if you do not intend to hang your TV on the wall. The picture quality if amazing, like the LCD, they are able to display any formats available today, including the new 1080 progressive (double high definition). They do produce some heat, but it is usually not more than a Plasma TV. DLP’s are usually the cheapest price for a very large size TV that you can get that still has phenomenal quality! The main drawback to a DLP, other than the depth, is that it has a user replaceable bulb that depending on the model lasts between eight to fifteen thousand hours. The bulbs cost anywhere from $200-$600 depending on the brand.

TV Support
Don't want to do it yourself, visit Azinstall.com to have a certified installer fix your problem or install your plasma or lcd tv.
Problem: No picture on the TV or it’s the wrong picture.
Solution: First, make sure the device you are trying to use (satellite, cable box, DVD, etc.) is turned. Devices can be hooked up to the TV on either a TV input or channel 3 or 4, so you should turn the TV to channel 3 and then 4 and see if that fixes the problem. If not, then change the input on the TV, pressing an input or source button on the remote control usually does this, sometimes you can press the channel down button until the TV says Input. Scroll through your inputs until you see the desired picture. If you still have no picture then your problem is most likely more complex, for example, a cable may be unplugged, or something may be broken. Also your picture may go through a surround sound amplifier and you may need to turn that to the correct input or source along with the TV.
Problem: No sound or the wrong sound coming from the amplifier.
Solution: Your surround sound receiver or amplifier is most likely on the wrong input or source. Try going through all the inputs on it until you get the desired sound. Another possibility is the amplifier may be on mute, or the speakers may be turned off, press mute or speakers A or B to fix those problems.
Problem: There is little or no sound coming out of the rear speakers.
Solution: Most of the time the rear speakers are not making much sound because they are mainly used for effects. You can change the signal processing (sound field, entertainment, pro-logic I or II, DTS, DTS-EX, 5 6 or 7 stereo, or THX) to turn on the rear speakers. If there is sound but it is really faint, you need to turn up the volume on the rear speakers. To do this you need to consult your owner’s manual about setting up the speaker level.
Problem: The TV picture is very blurry.
Solution: Most of the time this is because the TV is getting old and may need to be replaced. The connections in the back could be loose also but this is less likely.
