SOURCE: 52 mitsubishi has small white dots of light that dont go away on most of the screen

Mitsubishi is replacing these DMD IC chips nationwide under an unannounced kind of recall for model #'s WD60C9, WD73733, WD57734, WDY657, WD73734, WD65735, WD60735, WD65C9, WD73840, WD65833, WD65733, WD73735, WD73833, WD57733, WD65734 and others. Call them @ 800-332-2119 and give them your model, serial # and date of purchase, tell them you have the white spots, they will set up a workorder with a local Mitsubishi servicer to come to your home and replace the DMD chip. Mitsubishi will supply the part (part # 276P595010) for free, but you must pay $200 in labor. BUT...if you ask for Shantell Hebert when you call Mitsubishi, and really push the issue, she will also pay half of the $200 labor fee, so you go from $400 to repair to only $100. Once that chip is replaced, the unit works great again!!

SOURCE: White dots appearing on Mitsubishi 1080p DLP tv.

Actually you must replace the DLP chip that is buried deep in the works of the tv. Unfortunately this can run into a nice lump of change. Do what I did. Perhaps you've heard the old addage

SOURCE: Tiny blue dots and ablue cloud at the bottom

There is a possibility that the symptoms that you described is covered under an additional warranty, even if your set has been out of warranty for years. Sony has a site that describes this repair at no cost to the consumer: http://esupport.sony.com/perl/news-item.pl?news_id=127&mdl=KF50WE610 If this is not covered, then, the blue light panel is going out and that means it needs a light engine. Good Luck

SOURCE: Small white dots are showing up on the screen when

The white spots you are seeing are a result of dust or dirt in the light asm. Mits knows about this as a problem. The inside chamber of the tv needs to be cleaned. If your tv is in warranty they will come to your home and fix it. If not it is very easy to damage the tv by trying yourself, start with cleaning out the chamber that the bulb is in, use compressed air to blow out dust and dirt, them on the sides of the tv are round flaps that will need to be removed and this will go into the main mirror chamber, be careful but blow out any dust or dirt you see on the mirror. I would have a repair tech handel this unless you are skilled in this area.
good luck

SOURCE: I have White and black

I developed white spots on the screen of my Mitsubishi WD-57734 in increasing numbers over days and weeks. I called a repair service who quoted me $1500 to replace the light engine. He suggested I call Mitsubishi Customer relations at 800-332-2119 option 5 which i did. To make a long story short after several conversations with them they agreed to replace the part for free if I picked up the labor (Would have been less conversations if I had the original purchase receipt). Instead of $1500 I paid $250. The tv was only 3.5 years old. Perseverance paid off.

Why does my mitsibishi wd-607365 has white and black dots on it


After years of usage, the Mitsubishi WD-60735 starts to show some white dots, they begin to increase day by day all over the screen.
The problem is related to the DMD chip Part# 276P595010.
The part is about $200 you may find it used and cheaper on ebay.

Good luck

I do I fix white dots on screen


Hi
Have you tuned the channel frequency tuner? Use the remote to bring up setup menu on TV, scan channel frequencies & save. If it's an old TV that can't pick up digital signals, then you need to get a digital set top box & tune to TV.

Little white dots in tv modle# wdt657 what are they how can i get them off


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.

White dots on my mitsubishi WD-73734 tv screen


Your tv is a DLP projection one. In it the image is generated by projecting light on a chip that is covered in tiny mirrors that reflect more or less the light towards the screen. In your case some of those tiny mirrors are no longer controlled - they are immobile and reflect fully the light so you get a white spot on the screen.
The DMD chip that holds the mirrors is dying and you will have to replace it. This is the only place i could find that claims to have it on stock. You can also go thru Ebay, in there you will find second-hand ones extracted from defective tv's.
It's installation is strictly a job for a person with great tv repair experience - too many thins can go wrong in there if the job is not done properly.
