After the tv is on for about an hour or two the picture starts getting distorted at different places ( like water on oil paint)...slowly it gets worse all over the screen. then when i turn off the tv for about half hour and put it back again..it will run normally for another hour or two hours before the problem begins again. i called couple of repair places. one said color whell problem. othe said color processor problem is this the same problem as color convergance where a amp is required? if so where do i get it?

Re: smeared color image
Since this happens after the set warms up, I would check for bad solder connections or capacitors on the convergence board. If the problem was not readily apparent, then I would consider replacing the board, as I believe the replacement board has been upgraded from the original.

To get it absolutely back to normal you would have to remove the casing and re-align the inner workings. The only other option would be to go to your menu and adjust the settings, to return color and images to as close to normal options.
Hi,samsung has 3 major failures.The 1st one is the lamp, which averages 6000-8000 hrs 2-4 yrs.When it's about to go bad it shuts off and on or image won't come at all.You can find your part here:http://www.discount-merchant.com/SearchResults.asp?Search=BP9601472A Another problem that causes tv to shut off is the ballast,which is the board that powers the lamp.It makes clicking sounds and will cause pic to flicker.The other problem is the color wheel .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.Have a bless one!
Hi,do you mean tv is showing an amber picture? If you do,it could be an issue with the color wheel or dmd board.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.This is how the DMD 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!
This is a picture tube type TV. No lamp. You don't describe the distortion. A colour green picture that is twisted and shifted away from the other colours is a convergence problem. see Projection TV Convergence on this site. If the green is smeared, out of focus, larger than the other colours like a halo around objects, things like that, it is the green picture tube. Sony has discontinued most of the picture tubes so you may not be able to get this fixed.
I hope this helps you but you might wanna look into some other posts too cause it goes farther then the lamps and color wheels. Basically it's a bad product and the consumer should be fixing it. But your problem seems to be the color wheel. Or just a good cleaning. We replaced the lamb in ours and still had a color problem. We're gonna do an exstensive cleaning and dusting of our unit and if it don't work. We're going straight to the manufactor. This is enough with this product! It's costly to repair and still don't have the quality picture it should. It's more then a simple fix and too costly for ppl to just fix and move on. For how old these products are this all should not be happening.
Color Wheel problem.. to generate colors on a dlp the light is shine through a motorized wheel. that has different color filters on it. this is a motor and anthing that moves will eventally wear out. i just replaced the color wheel on a samsung today. standard for this to go out in about that time. i believed our shop charged 250 to put a new one in.
