Light sensor is going out pixel dots on screen

Hi.

Basically the white dot is a dead pixel, this is common with LCD screens. You have nothing much to worry about unless the screen develops more dead pixels which could lead to a screen replacement although its highly unlikely.



Regards.

HI,
Are you sure that there is balck dot on the sreen. Check one more time is it any dust on the screen.
Black spot Means pixel of the Lcd sreen is fault. There are thousands of pixels in an lcd screen. when any of the pixel or a group of pixels become faulty the black spot will appear. Its not possile to rectify the problem other than replacing the LCD panle if its avilable. The avilability of lcd screen is very rare.

If the white pixel dots start to multiply then Problem will be in the DMD board or the Light Engine.

Hi gailandst632,

I saw you post stating that you have pink spots/dots on your Screen.

to determine what the problem is we weill need to turn your computer off and boot into the BIOS screen.

1. Turn your Computer Off, then as soon as you power the machine On keep on tapping F1 on the keyboard to get the BIOS screen it will be a Blue screen with white fonts on it, in that screen see if the pinks dots are present or not.

2. If the pink dots are present in BIO then that means that the LCD screen of your Laptop needs to be replaced.

3. You will need to call your manufacturer regarding this concern check if your system is still in warranty, because this will be very expensive if you are out of warranty.

4. All manufacturers will cover a pixelated LCD screen if the dots or pixelated area has at-least 5 or more dots/pixelated areas on the LCD screen.

I hope that his will help you with the concern that you have posted.

Have a nice day.

I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

The snowy dots and dots are typically from a poor signal going into the TV.

If there are colored pixels that stay lit all the time (like a red pixel and never goes away) and for any input, that’s called a stuck pixel.

A stuck pixel may be caused by a bad Y-Sustain, Y-drives, Z-sustain, and or a bad plasma panel.

Good Luck.

Hi,Yes your problem sounds like the DMD board.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 screen. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!

Hello. If it resembles a tiny bright green dot, this is most probably a dead pixel. In the troubleshooting guide in the user manual, the manufacturer states that some pixel loss is normal--either they will be gone or permanently "on". If the unit is new(i.e. still under some warranty) talk with the supplier about options--they *may* decide to replace it if the dot is in a particularly annoying location. Be aware though, they won't be under obligation to do so. I own a LCD projector with a few visible pixels--as devices such as these(lcd tv's, projectors, plasma, etc.) age, this type of phenomenon is going to occur. Normally--and this certainly isn't always true, there is a tolerance of 3-9 pixels. Check with the supplier and/or manufacturer for individual specs. Especially if the unit is under warranty!--Hope I successfully assisted you.---Rick

The solution you can try is to run a function of the camera called Pixel Mapping to see if this removes the dot as it will redistribute the pixels of the camera on the LCD screen. To access this function - have the camera in shooting mode - go to Menu - right arrow to setup and press Ok - down arrow to pixel mapping and right arrow over to highlight start and press ok. The camera will try to repair itself. If after running this the dot is still there then you may need to send the camera to Olympus for service as the image processing chip may need to be replaced. http://olympusamerica.com/cpg_section/cpg_servicerepair.asp
