LCD TV Repair:
Diagnosing and Fixing A Lcd TV With No Picture• Problems can often occur with even relatively new LCD TVs. Some customers report their screen going black shortly after turning on the television, even though the TV's speakers continue to produce sound. You can test and rule out a number of things before concluding that your TV has a hardware defect.
First, check the input settings of your television. Often, users will experience a dark screen when first turning on their television if the selected input corresponds with a turned-off or unplugged input, such as a gaming system or DVD player. If the problem persists, try reconnecting all cables on the back or sides of the television. It's possible that one of your cables has gone dead. If you have access to other cables, try swapping these in and see if the problem persists. Some customers report that turning the television off and unplugging it for an extended period of time, up to 24 hours, can fix the black-screen issue.
Power Supply Issues
• If you've tried all of these suggestions and problems persist, it's possible that the power supply inside the television is defective or broken. The power supply for most LCD televisions will cost around $150, with labor costs of around $250. Unless you have a fair amount of TV repair expertise, this is probably not the sort of repair you'd attempt yourself.

LCD flat panel televisions info:
LCD TV is a flat panel television that utilizes the same basic Liquid Crystal Display technology that has been in used for some time in cell phones, camcorder viewfinders, and computer monitors. LCD panels are made of two layers of a glass-like material, which are polarized, and are "glued" together. One of the layers is coated with a special polymer that holds the individual liquid crystals. Electric current is then passed through individual crystals, which allow the crystals to pass or block light to create images. LCD crystals do not produce their own light, so an external light source, such as florescent bulb is needed for the image created by the LCD to become visible to the viewer. Unlike standard CRT and Plasma televisions, there are no phosphors that light up, and, thus LCD panels are thin and require less power to operate. Because of the nature of LCD technology, there is no radiation emitted from the screen itself, unlike traditional televisions. Also, without the need for a picture tube, LCD televisions can be made very thin, thus allowing them to hung on a wall or placed on small stand on top of a table, desk, dresser, or cabinet very easily. Combining the above technology with the features of a traditional television, such as, AV input/output connectivity, side or bottom mounted loudspeakers, TV tuner, and traditional television adjustment controls, bring to life a concept that is becoming a popular option for TV and home theater viewing.
