This could be something on the lens or mirrors. you can open one or both porthole covers on the left or right side of TV to determine if this is the cause. You can look at the mirrors & lens to determine if a bug or dust has gotten on either part. Then clean.
HOWEVER, the most likely cause is the DLP chip. this causes white & or black dots. May start out as one or two, then multiply.
I have a Mitsubishi TV and had the same problem. There is a mirror that moves to control each pixel. When some of them fail to move you get the white dots. Google your problem and a company will come up(sorry forgot the name).,you can buy the new part from them and they have exact utube videos to help you do the repair. Took me about an hour. Part was around $150. Very rewarding feeling when you turn the tv back on with no white dots.Still dot free after two years
Your TV is DLP projection TV. DLP is Digital Light Processing. Digitally processed light coming out of DMD (Digital Micro mirror Device) is projected on the TV screen. This DMD is made of thousands of tiny mirrors & the size is about 0.7 inch. These mirrors are fixed with tiny hinges for its movement. They reflect light as per processed signal. DLP is invented by Texas Instruments. When there are dots on the screen, that means the tiny mirrors representing the dots are stuck in its position. If the dots are few & the viewing is bearable, just leave as it is. If the dots are more than bearable then you will have replace the DMD chip which is quite costly.
Your DLP chip is failing. The tiny micro mirrors within this chip are stuck. More white dots will appear over time until it looks like a star field on your screen. Most places will tell you that you need a new light engine, however you can replace the DLP chip itself and it will take you about 30 mins. You can find the chip online for around $349 but I think I have DLP chip you need brand new for $225. If you are interested in this contact me. [email protected]
Hi,
white dot is from a failure in the dlp chip. it controls 1000s of tiny mirrors which help make up your pix, when the mirrors get stuck a white dot appears. over time more will pop up. Probably in the $300-$500 range to have someone repair.
sound like you have a bad dlp chip. this happens to a lot of samsung dlp tvs. some of the mirrors are stuck. they can appear as black dots or white dots and it usually gets worse over time.
your dlp ic is going bad and needs nto be replaced. some of the mirrors are getting stuck they will appear as black dots or white dots. it usually starts as one or two and will continue to get worse over time.
The random whit dots you are seeing is more than not the DMD or million little mirrors board. The white spots represent some of the mirrors that are sticking in the on position. In that case they are always reflecting white light from the lamp. I don't concider the DMD board a do it yourself repair since on the older DLP set it requires mechanical alignment as well. The best thing to do is contact a techincian and see what they might charge to repair the TV for you. Please take a few moments to rate my answer...Thanks..
