Television














Television is a broadcast picture tentacle. The word television comes from the words "tele" and "vision", which means each distance (tele) and looks (vision). So television means visible or can be seen from a distance. Television is paralleled by the discovery of the wheel, because this discovery could change the world civilization.
In the discovery of television, there are many parties, inventor and innovator who was involved, both individuals and business entities. Television is a mass work developed from year to year. Beginning from the television would not be separated from the basic discovery, law of electromagnetic waves discovered by Joseph Henry and Michael Faraday (1831), which is the beginning of the era of electronic communication.
Grid consists typically of a modern TV viewer devices, antennas or input radio frequency (RF) (usually a connector F), and, most important, what distinguishes a TV tuning of the monitor TV boxes that receive signals that have been processed, do not forget to also magnifying the sound. Most TV box also features an additional input terminal to other devices such as DVD players, video game console and font of the head. Input terminals of the most frequently encountered, including RCA (for composite video and component), mini-DIN (for S-Video), HDMI, SCART (Europe) and D-terminal (Jepun). Half a luxury TV box Ethernet port is equipped to receive data from the Internet, such as value stocks, weather or news. Most TV boxes made since the early 1980s is also equipped for infrared pengesan dihantar impressive gesture by a remote device.

Sanyo Television










In a move right out of Japanese kabuki, we've reduced the depth of our innovative TVs by 30-40% "Slimmer" for a stylish space-saving profile. SANYO's special cathode ray tubes (CRTs) made it all possible. You enjoy richer, more natural colors without any screen artifacts even when viewing the fastest onscreen action.

In addition, the CRT's flatness minimizes any possible viewing distortion no matter what the watching angle. Combine it all with dynamic sound from the built-in Surround Sound System and extended low frequencies from the Bass Expander System, and you get the most technologically advanced TVs around.

Plasma Television













Plasma TV screen using the technology in the form of small glass balls that contains the gas called plasma. When electricity flowed, the plasma gas is ultraviolet rays that burn out the glass coating on the screen. As a result, the screen changes from black to any color. 
That's the fundamental difference of plasma TV technology with LCD TVs. There are still many other differences of both technologies, such as size and flat screen technology. 
LCD TVs have limitations in terms of its dimensions, as originally designed as an LCD computer monitor. Currently, the largest screens are made by Samsung, which has size 46 inches. TV was launched mid-year 2004, having previously shown at the exhibition of electronic and household equipment in New York, last April. Therefore, the size of LCD TVs are generally located in the market currently ranges between 15, 17, 20, up to 22 inches. 
Plasma TVs have a screen size much bigger, designed for audiences who liked the TV screen above 37 inches. The size of the plasma TV can reach 76 inches. So, no wonder if the fans picked him to put together a large screen with home theater devices. 
But once the plasma TV owners should get ready with skyrocketing electricity bills. This was because of the power consumption of plasma TVs doubled from LCD TVs. The main reason there? Is the cooling system of the screen. 
Plasma TVs need a fan for 'cool' plasma TV screen that is not too hot when used in a long time. Therefore do not use the combustion process, the LCD screen has a life longer than plasma screens. 
FROM TV image display side, both having different characteristics. Plasma TV screens tend to be not properly display the color black. In fact, even compared to CRT TVs, plasma TVs are still lost in the production of a dark black color and dark gray shades. Another problem of static images for long periods such as logo of the TV station could not quickly disappear from the screen. His shadow still lagging behind despite the TV broadcast has been moved to other impressions. 
In the matter of the quality movement of the picture, plasma TVs have the advantage capable of displaying images of fast moving images. So that the displacement images like action movies (action) better watch on the plasma TV. Then viewed from the standpoint, plasma TVs have advantages can be watched from every angle, like conventional TV. 
Normally plasma TVs sold in the form of video displays, so that still must be burdened with buying a TV tuner (tuning wave) and the speakers. 
Instead of LCD TVs already sold complete with speakers and tuner. LCD TV screen has the ability to display a clear black color. To find comfort in watching, eyes must be directed straight at the screen. When viewed from the other side, who looked only a shadow only. The advantage of LCD TVs is not require excessive cooling system, so that his voice is more smooth than plasma TVs. So, it could be an option for requiring the screen to the computer and watching TV. 
Contrast plays an important role in producing images that comfortable to watch. Value refers to the darkness or brightness of the screen. The higher the ratio the better the picture display. 
Average LCD TV has a contrast ratio ranging from 400:1 to 800:1. Plasma TVs ranging from 600:1 to which art has the ability to 1.500:1.

Sharp Television

Samsung Television












This time post will explain about the experience improvements in Television Samsung 14-inch model for all types of chassis KS1A, to type their own chassis you can see at the bottom of the chassis is usually near the PCB transformer FBT. Chance to fix my TV yesterday was the 21-inch model.
Symptoms on this Samsung TV itself is power off, the components that have been tried replaced the Power Tr 6810A that after the new replacement was short again, then deflection yoke is also replaced with a new one but it still shows the damage that sama.Tentu just another cause damage similar to there are many, but so you do not run out of stock of TR power for damage like this I suggest you also read my previous posting about Tricks Preventing Power Transistor Short. Ok so hopefully useful post this time.
Oddly enough when the TV is turned on but conditionally revoked deflection yoke power transistor does not break / short again, after the check was not on the TR damage or deflection yoke power but on the horizontal 680pF capacitor 1K2V the resistance has changed, although not short.
