I have a 61 inch dlp that has a grey spot on the screen. We have no idea where it came from or how to get rid of it. Does anyone have any suggestions???
it looks like someone pushed up against the screen. But no one was that close to it. It is a blob type circle...ish It just popped up today. The tv has been on all day and we were wondering if it might be the lamp??it looks like someone pushed up against the screen. But no one was that close to it.

How big of a spot ? Is it a blob or is it symmetrical ? Did it show up slowly over time or just pop on screen one day ? I might be able give you an guess with these answers.

It's not the lamp. It maybe dirt or dust or even a bug. The picture that is projected starts out 1/2 inch by 1 inch in size. Somewhere along the path to the screen a piece of dust gets in and after it's projected it looks like a blob on the screen. The closer it is to the DLP chip itself the bigger it looks. If this is the case you should have a professional service it. The Light engine needs to be removed and cleaned. If you lightly push on the screen does the blob move slightly ? If it does it's not on the screen it's in the optics or the mirror. You may also have a bug or smug on the main mirror that causes the same thing. This will appear about 2 times the normal size of the object. If your up to removing the screen Take a look closely at the mirror on the back of the set. You can clean this with windex it's glass. If you do take the screen off hold it up to the light. Sometimes spiders make webs and leave marks. Good Luck

The DLP chip is failing and will have to be replaced. Samsung is covering the cost of repair for this problem on SOME models. You can call 1-800-samsung to find out if your unit is covered or to find the nearest service center.
Hi if your tv is a dlp it might be an issue with the DMD board 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 screens. 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!
