Question about Computers & Internet

What is an Samsung UN40D6500 LCD TV? LCD TV Liquid Crystal Display, which stands out from the bulb or CCFL Cold Cathode Fluorescent Lamp, which is a thin tube like a drinking straw. By horizontal long as the light source and a semi-solid, liquid crystals, Liquid Crystal as well as three colors red, blue, green, bending forward so that the angle of light from the lamp CCFL Backlight shines through out the colors. What is an LED TV? Stands for Light Emitting Diode LED TV LED is lit. "Tiny but nice", which uses the LED as a light source and a Liquid Crystal as a crystalline solid, semi-liquid, three colors red, blue and green are bending the angle so that light from the LED shines through out the color. different. Summary. This is the idea that LED TV LCD TV is switching from CCFL to LED bulbs in lamps and light enough to use a semi-solid, liquid crystals, Liquid Crystral three colors to create a pin for each cell. Therefore, in accordance with its LED LCD TV is it just switching from CCFL to LED bulbs and lamps for light. Another example is that LED technology is seen frequently in the Notebook that I have. LCD TV and LED TV with nothing better than a Hla? I decide to answer it. The touch screen is a LED TV almost every day in many respects is better than LCD TV. Let's compare the qualitative results do not. It is judged by a team. LCDTVTHAILAND. With a light bulb. "Tiny but nice" by the ability of the LED can be provided. "Light is better to use less power," the LED source is the more efficient lamps CCFL right here and more importantly, with the tube diameter is smaller than the LED TV is thinner than the LCD TV would go to the lamp CCFL. Backlight LED TV, but is still high at this price level raises the question comes up saying. "Worth it" to the investment in this period. In short I can say that the value of LED TV LCD TV is quite expensive, but it also has the power LED TV LCD TV is less than about 40% -50%, so it really is. Therefore, the values ??are based on our own, then that option is not Hla. There is a LED TV? This many people may still wonder whether it is a multi-LED TV with me. I decide not to have a variety. Each model has different advantages and disadvantages. Let's do better. 1. EDGE LED: LED bulbs are placed at the edge of the TV. EDGE is a saying that "edge" on the LED lamps will be placed on the lower left and right edges of the TV and keep shooting into the middle of the TV screen. Another advantage is that for "thin" LCD TV is thinner than normal, because LED bulbs are just as many on the side. The other story is about saving it. However, the main disadvantage when compared with the LED is not possible to do a Full LED Local Dimming or turning on / off light bulb into groups because there is an edge. EDGE LED TV for the latest Samsung B6000 B7000 B8000, and it includes Sony ZX1 is the thinnest EDGE LED LCD TV in the world, only 9.9 mm 2. Full LED: the LED panel on the back. For the second we call Full LED (Direct LED) as a light bulb, do not the whole panel will be light enough the advantages of Full LED, or a camp called Direct LED is capable of making Local Dimming or turning. on / off the LED bulbs into groups or only itself independent as the other one on the left is black. On the right is a white light LED Backlight and the left will be off to the dark side the dark and LED Backlight right turns, so that light can penetrate into the white on the CCFL and EDGE LED is not. The downside is that it can be the thickness of the unit. Because of the multiple LED lights on the back of the screen. The TV has a thickness of about LCD TV is not common. The obvious example is the Samsung A950 is a Full LED Backlight on the Philips model PFL9803 the EISA Award winning Full LED Backlight models used as well. 3. RGB LED: red, green, blue LED lights behind the panel. The last I raised the top of the LED TV in it, which is the RGB LED TV itself by the principle that light is similar to Full LED, but instead of using the LED color, usually white in. The light RGB LED TV LED bulbs use three primary colors (red R, green G, blue B) in a light bulb instead of the three colors separately and independently. Resulting in better color reproduction. I stub out the light colors first. The accuracy and clarity of color is more. As well as the ability to track the depth of the colors better. Principle, RGB LED LED TV is not the best. Costs are higher. And can take in the Local Dimming or turning on / off into groups independently to black blacks and contrast, the greater will be the same as the Full LED is the 2nd on the downside. The key is that the price is quite high right now. The TV using the RGB is the Sony X450 and 46 "55" 70 "and Sharp XS1 size 65" which is the Sharp RGB LED TV is 699990 and 70X450 priced at 799,990 baht towards the car Vios and Civic as the first. I just do not Hla. It is better to buy it Hla. Help me? But the CCFL LCD TV, EDGE LED TV, Full LED TV, and RGB LED TV is different, good and bad points to it. The price level is higher along the edge of technology. The subject. "Value" in buying it. It is up to the satisfaction of more With the economy like this. Many of you think that's enough to buy a LCD TV. The picture is not inferior to the yellow LED TV does not have the money to buy another. Or some power-saving LED TV to see that over the long term. It is an investment worth more than Or you want a TV that's best quality. The dispute about the price, it may be up to the top RGB LED TV to buy it for quite a waste of time and money on a lot of gold as a "great value" It is up to. "Personal satisfaction".

SOURCE: "failure of "cold-cathode-fluorescent-lamp"

they can be repaired by an electronic tech but are cheaper buying a new one. The cost of new inverters range from 30-80$ USD. Viewsonics don't cost that much and now you can get 18.5 inch widw screen acer or other brand lcds for 89$.

i woudl really suggest just buying anew unit.

My toshiba satellite a215-s7472 screen is very dim can hardly see anything what do I do too fix it I tried ajusting the light .


Primer:

An LCD screen does not produce light by itself. It needs an additional light source.
A Backlight is the additional light source.

A Backlight can be a CCFL, or a series of LED lights.
(Two present technologies being used)

The Toshiba Satellite A215-S7472 Notebook PC uses a CCFL.

A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

(Average size is 2mm by 334mm. In inches that is;
Approximately a little thicker than 1/16th of an inch Thick, and a little over 13 inches Long)

A screen Inverter is used to convert the power (Electricity) from the laptop, for the Backlight, and LCD screen.

Point of all this?

90 PERCENT OF THE TIME the fault is a bad Inverter

http://www.zkarlo.com/selected-zkarlo-part/inverter-board-p907.php

HOWEVER, the Backlight bulb is located inside the Screen Frame, of the LCD display assembly.

An LCD screen is composed of layers. These layers are held in a specific pattern, by the LCD screen frame.

This is a thin metal frame which surrounds the LCD screen layers, and has Philips head screws which hold the frame together.

NOTE*
The procedure is fairly intricate.

Will power up then gos to stand by mode but no show on screen do these lcd have lamp/bulb


It has CCFL (Cold Cathode Fluorescent Lamp) similar to your home Fluorescent lamps in your home.
Most problem with no picture is due to bad power supply not supply 24vdc to the Backlight Inverter board or bad backlight inverter board, that is what you have to determine.

Check for a backlight failure by holding a flashlight on the screen at about a 30-degree angle, a couple of inches from the screen. Look at the area around the flashlight beam. If you see video, either your backlight fluorescent tubes are burned out or the inverter has gone bad. If you need tubes, search for "CCFL replacement" (CCFL = cold cathode fluorescent lamp").
