I have a toshiba HD DLP TV model 57HM167 and white spots have started to appear on the screen for about a month now. There are over 15 white dots now and I cant find an answer on how to fix it. I was told it might be a DMD chip? If so, where do I get parts to fix it?

Thats caused by the DLP chip. Unfortunately most Toshiba models will end up having to have both the DLP chip and the formatter board replaced at the same time to fix the issue where as other models only require replacing the DLP chip alone to fix the white dots issue

White dot for DLP Projector TV is not because of the light buy. It is caused by aging DLP chip ( DMD Chip.) Your TV DLP Part should be the following image:

Hi, I have a mitsubishi 65" DLP model # 65733 that I bought in December 2007 brand new, about six months ago I started spoting white dots on my screen that started blinking and then became permanent, thinking is was dust I cleaned everything inside with compressed air without success.
The stars multiply daily to a point that it was intolerable to watch anything with all the white stars and a few black ones that showed up.
We called mitsubishi but got no where, I was out of warranty. (they still deny having a problem with their DLP's)

I had a service tech inspect the tv and was told it could run about $800 to $1000 to replace the light engine with refurbished parts with 90 day warranties.

Researching on line I came across a DLP chip that is compatible with several mitsubishi and samsung models, so I decided to chance it, and replace just the DMD chip before we trash the tv, it was unthinkable to pay $800 to repair a tv that we could buy now for under $900.
Thanks God the "gamble" paid out and the problem got solve with just $150 DLP chip in about 15 minutes of my time.
If you are not mechanically nor electronically inclined, I recommend you use a technician for the installation, but don't let anyone tell you you need to replace the whole light engine, it is a ripoff.
If your problem is just white or black dots on the screen that do not move.......this will solve your problem!!

P.S. Hope this will help you and for the record..... "I will never buy a mitsubishi product again".

This unit uses a DLP (digital light processor) chip and if this starts to fail then you will get spots appearing on the screen. The DLP chip will need to be replaced.

<span id="ctl00_ctl00_MainColumn_CenterColumn_ThreadSolutions1_Repeater1_ctl00_lblSolution">DLP/mirror chip is going bad. A common problem on Sammy TVs after 2-3 years. Chip is user replaceable (try samsungparts.com or ebay) for about $150-200. Sammy was (last year) repairing the DLP White Spot problem for free. You MUST talk to ECR (executive customer service) to even think about getting that consideration--forget the standard CS people. Don't know if they are still covering this out of warranty in 2010.</span>

If you get White or black dots all over the screen (DMD symptom)
If you get a pixilated picture (DMD Board)

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..

If the white spots are appearing in different spots or "Moving" it is the DMD board beginning to fail. Samsung DLPs seem to have a lot of DMD board failures. I would expect it to completely fail in the next couple months.

If there are only a couple small white spots that never go away it could be a mirror that is seized on the chip, but it's far more likely that the DMD board is going bad.

If your Mitsubishi TV has white spots in the picture , you can call Mitsubishi @ 1-800-332-2119 and request a free DLP Chip to fix the problem. They will send the New DLP Chip at no charge to a TV Tech in your area to install it for $200 flat rate. That is about a $250 savings if you had to pay for the chip . Call them with your TV's Model number and serial number and let them know when and where you bought the TV.
It saved me some hard earned money and now my TV is like New !
