The picture is distorted by both vertical and horizontal lines (different colors; pixelated)


A distorted picture display soon after the Plasma TV is powered on has two indications. First, a picture display of pixels when the TV is powered on is usual prior to signals of video movies are acquired from broadcasting station. The movie from braodcasting station should display without noticeable objects of distractions. For example, the movie displeyed on the TV without obstructions is indication that the problem is from the display set. Alternately, movies with poor capability to display on the set is indication that the media from which motion pictures are acquire from is malfucntioning. For example, a TV connected to cable network or disk network or satellite broadcasted signals with receptive compromises are diagnosable from two areas. First, a clarification from the network station that has setup connectivity of devices. Perhaps a device in the setup is malfucntioning. Second, attempting the adjust the phsical connections that are attached to the TV is capable of resoving the problem. Refer to the user guide for what is default expectation on powering on. Thereafter consul technical experts if required. Good luck

What are the possible disadvantages of computer monitors?


Monitors, otherwise known as displays or screens, currently come in two formats: LCD and Trinitron ("the boxy thingy").
LCD pros: Flat, low radiation (as far as I know) LCD cons: displays can either come with or develop "dead pixels" - pixels that remain a solid color or display black, are very fragile - pressing the display surface is not "healthy" for the display
Trinitron pros: deep color Trinitron cons: relatively moderate-to-medium radiation
Both types of displays can suffer from "screen burn" - if an image is displayed for too long (several hours/days) it will permanently "burn" itself into the display and be visible at all times.

Samsung DLP model#HLP4663w.green hue on the screen,what is the solution to my problem.


Hi,It sounds like it could be the color wheel or DMD.The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises. The DMD is another possibility.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q One simple test is to display menu and if it's affected then most like will be an issue w the DMD board.Found the complete set with color wheel and DMD included here: http://www.discount-merchant.com/SAMSUNG-30407272050-Light-Engine-w-Color-Wheel-p/1139314.htm Have a blessed one!

Used to be white lettering now top green bottom pink 60 inch rear projection 5 years old


Hi,do you hear buzzing ,whirling,or high pitch sounds?If you do it could be an issue with the color wheel.The Samsung BP96-00674A color wheels spin anywhere from 6,000 to 15,000 revolutions per minute (RPM’s)--It is one of the few consumable parts in your Samsung TV. The average life expectancy from our data logging shows the Samsung color wheels are fairly reliable with a MEAN average of 5-8 years But it could also be the Dmd board this is how it works: http://electronics.howstuffworks.com/dlp1.htm Baisclly the DMD board creates the images and colors through its chip that has 2 million pixels,when that chips goes out you'll see either lines ,pixelation and dicoloration.One simple way to see if it is the Dmd its to display menu if it's also appears distorted that will be what it is.

Sony a100 distortion dots - Im getting several


If these are single pixels on the LCD screen, they are normal. From pg. 8 of the user's guide:

"The LCD monitor is manufactured using extremely high-precision technology so over 99.99% of the pixels are operational for effective use. However, there may be some tiny black points and/or bright points (white, red, blue or green in color) that constantly appear on the LCD monitor. These points are normal in the manufacturing process and do not affect the images in any way. "

This may also be helpful.

"images may trail across the LCD monitor in a cold location. This is not a malfunction. When turning on the camera in a cold location, the LCD monitor may become temporarily dark. "
