There are three color projection tubes in this puppy. Which one you gonna play with? All three have a control grid in them. One can't help but wonder why someone would want to do this.... To access the control grid of any cathode ray tube (and picture and projection tubes qualify), the set will have to be take apart to permit access to the internals. Note: if you are not at all familiar with electronics and what precautions are necessary when working around high voltage, leave this one alone! That said, a peek inside will reveal the three projection tubes in the back, and the easiest way to access a control grid would be to find the wiring harness and plug assembly that hooks up to the back of the projection tube to connect it to the circuitry that drives it (the circuit board). Now listen up. Information is provided here because someone wants it. The individuals who use the information without care and knowledge do so at their own risk. You can be injured or killed by connecting yourself to energized circuits. And the tubes run hot! You can be burned by them. Lastly, it is a know fact that individuals who are curious about stuff are gonna get the information they want however and where ever they can. It is provided here because it is firmly believed that, since the info is going to be gotten regardless, by getting it here, the curious person can be fully advised of the hazards possible in working on something like this. There is no good reason to fool around with the grid wiring (or any other wiring) on the projection tubes of a $1000 + Sony TV. If there is a problem with the set, it almost certainly isn't with the wires. It don't work dat way. Be smart about this one, Sparky. The life you save may be your own.
Color TV broadcasting was invented in 1953
Color TV; the slinky; diners; Seventeen Magazine; frozen dinners; and a bunch more
The worlds first colour television broadcast took place on January 1st 1954. Actually, not quite the question. Colour television (using a rotating disc fitted with coloured filters) was demonstrated by John Logie Baird to RCA in 1939. His first 'proper' colour television system was demonstrated in 1944.
During 1940's there use to be radios for watching, and alson in the 1950's. In the 1940's people used radios without screens, not cable TV. In the 1940's the radios had speakers, and no screen. In the 1960's people had black and white TV, not color TV. In the 1990's people finally had color TV, but it's not HD.
monochromatic means it can display only one color except black.Each pixel in Monochromatic crt contain a phosphor dot of one color whereas in color CRT the phosphor dot in each pixel contains three colors Red, green, blue(RGB).
The three color lights does a project TVs use are white,black,and i do not know the what is the third color
Some of the typical problems encountered with Sony projection tvs are the tube going out and the loss of color. Sony TVs are under warranty for the first year.
Large screen television is nothing new. John Logie Baird introduced the world's first television in 1925. By 1928 he had developed and demonstrated color television. By 1930 he had developed his color system into a projector and used it in cinemas and theaters in England. Projection television has now passed its eightieth birthday!
A DLP lamp is used to power what is seen on a rear-projection television, and is also used in modern color digital projectors. Digital cineman projection also used DLP technology.
Obviously this varies depending on where you live, but I've seen them anywhere from 9$ to 13$. Hope that helps.
the element of color
LED stands for light emitting diode. It is a kind of tv and monitor and they are usually known for being better than plasma and projection. The color is more vivid and the picture is clear.

Science played a huge part in creating color television. Each color in color television was created by burning different elements.
The first color television was demonstrated by John Logie Baird in 1928. It was purely experimental but showed the principle of using red, green and blue images to create a color image. The first commercial use of color television was in 1953 in the US. Although it was launched as a commercial service, the take up was poor. The new color system was not compatible with the existing black and white broadcasts. In 1956, RCA launched a new color television service that was fully compatible with the black and white services and that color system has remained in use until today. In the UK, color broadcasts were not started until 1967 when BBC2 was launched in color. Although the color encoding was slightly different to the US version, it has also remained in use until today.
in the 1950's color television started
NBC uses a peacock logo as a reference to its color broadcast of the Rose Bowl parade in 1954. NBC had greater access to color television technology than its competitors because it was a subsidiary of RCA, a television set manufacturer.
