SOURCE: Plasma TV-power light does not come on


most probably the fuse inside the circuit blown out, You should open the back of the tv to become circuit board visible. But this hard when novice do it.

To be sure that everything will be alright i would rather suggest you to bring the tv to the nearest service center. maybe warranty work for that.

SOURCE: Blue Bleeding on Plasma Screen

I was having some increasingly severe pixilation on the left side of my 42" Samsung plasma. After reading this thread, i took off the back of the panel. I cleaned all vents but made no adjustments as i could not find what i needed to adjust. The only other change i made was i unplugged the TV from my surge protector that had 7 other things plugged into it and plugged it straight into the wall. After turning the TV back on, i was pleasantly surprised to find that the problem was fixed. I'm not sure if the vents were blocked & it was over heating or if i had interference through my surge bar, but i do know i am more then happy that it is fixed!

Look like shadow and it is to much color

I have not repaired a plasma TV. As I understand, the plasma TV has a picture tube similar to those in older TVs. I have read about them, and have an authorization for two other TV manufacturers. The bulletins I have read described trouble shooting problems. Your TV may be exhibiting a blue or red hazing problem. This is most certainly describing a bad plasma screen. This problem is a common occurrence. Once again I have read many trouble shooting tips regarding this problem. Under warranty we are asked to replace the screens. If this TV is not under warranty, the cost will exceed the price of a new TV. Sorry, about your TV. You may opt for a second opinion, and please do so. Thanks for asking and show all hands of support!

Whats the difference between a LCD and plasma

Answer: Outward appearances are definitely deceiving when it comes to LCD and Plasma televisions. Although both types of televisions are flat and thin, they employ different technology in an attempt to deliver similar results. Plasma TV Overview Plasma television technology is based loosely on the fluorescent light bulb. The display itself consists of cells. Within each cell two glass panels are separated by a narrow gap in which neon-xenon gas is injected and sealed in plasma form during the manufacturing process. The gas is electrically charged at specific intervals when the Plasma set is in use. The charged gas then strikes red, green, and blue phosphors, thus creating a television image. Each group of red, green, and blue phosphors is called a pixel (picture element). Although Plasma television technology eliminate the need for the bulky picture tube and electron beam scanning of traditional televisions, because it still employs the burning of phosphors to generate an image, Plasma televisions still suffer from some of the drawbacks of traditional televisions, such as heat generation and screen-burn of static images. LCD TV Overview LCD televisions, on the other hand, use a different technology (see also question #1 for this same explanation). Basically, LCD panels are made of two layers of transparent material, which are polarized, and are "glued" together. One of the layers is coated with a special polymer that holds the individual liquid crystals. 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, since there are no phosphors that light up, less power is needed for operation and the light source in an LCD television generates less heat than a Plasma or traditional television. Also, because of the nature of LCD technology, there is no radiation emitted from the screen itself. Plasma vs LCD The ADVANTAGES of Plasma over LCD are: 1. Larger screen size availability. 2. Better contrast ratio and ability to render deeper blacks. 3. Better color accuracy and saturation. 4. Better motion tracking (little or no motion lag in fast moving images). The DISADVANTAGES of Plasma vs LCD include: 1. Plasma TVs are more susceptible to burn-in of static images. 2. Plasma TVs generate more heat than LCDs, due to the need to light of phosphors to create the images. 3. Does not perform as well at higher altitudes. 4. Potentially shorter display life span - this used to be the case. Early Plasmas had 30,000 hours or 8 hrs of viewing a day for 9 years, which was less than LCD. However, screen life span has now improved and 60,000 hour life span rating are now common, with some sets rated as high as 100,000 hours, due to technology improvements. LCD television ADVANTAGES over Plasma include: 1. No burn-in of static images. 2. Cooler running temperature. 3. No high altitude use issues. 4. Increased image brightness over Plasma. 5. Lighter weight (when comparing same screen sizes) than Plasma counterparts. 6. Longer display life used to be a factor, but now LCD and Plasma sets both have at least 60,000 hour or higher lifespans. DISADVANTAGES of LCD vs Plasma televisions include: 1. Lower contrast ratio, not as good rendering deep blacks. 2. Not as good at tracking motion (fast moving objects may exhibit lag artifacts) - However, this is improving with the recent implementation of 120Hz screen refresh rates and 240Hz processing in higher-end LCD sets. 3. Not as common in large screen sizes above 42-inches as Plasma. However, the number is growing fast, with 46 and 47-inch screen sizes becoming more common, and some LCD sets having a screen size as large as 65-inches also available to the general public. 4. Although LCD televisions do not suffer from burn-in susceptibility, it is possible that individual pixels on an LCD televisions can burn out, causing small, visible, black or white dots to appear on the screen. Individual pixels cannot be repaired, the whole screen would need to be replaced at that point, if the individual pixel burnout becomes annoying to you. 5. LCD televisions are typically more expensive than equivalent-sized Plasma televisions (although this is changing), especially when comparing EDTV Plasmas to HDTV-LCD Televisions.

Samsung Model: HP-R4262 42" Plasma Problem, pink pixelation/ghosting

Onece the plasma heats up it shrinks a little, i think the cause is that you are low on plasma, so when i heats it shrinks and since the plasma cycles, the area low on plasma wil move slowly around the screen, take this to a repairman and more plasma can be added to it.

Blue Haze comes out the left side of screen top to bottom about 3 or 4 inches.

What needs to happen is three specific voltages need to be adjusted on the power supply, You need to set the Ve voltage to 100v, the Vset voltage to 188V and the Vs voltage to 190v. Monitor the set for 24 hours, if haze doesn't come back the unit is considered repaired. If haze returns, then the problem is with the panel itself and wouldn't be worth it to replace because it will cost more than the tv cost you originally

Plasma tv only 18mts old has appeared with 3 green lines down the screen

I would check and see what the warranty is on this unit. It is either going to be a driver board issue such as a bad connection or a bad board itself. The other and most expensive issue could be the plasma panel itself which usually cost more than the set did originally.
