Any spots that are white are not dust on the output side of the bulb. This is a component failure. IF it was dust it would be dark spots.

as greg instruction, it is very detail,

usually, white dots problem is reason of the DMD. perhaps the manufcaturer can't directly and singly sell a parts for end user, they always let you send broken machine to their repair store, then ask for high repair cost.

actually, optoma HD67 projector with 1280*720 pixels, so i think you should buy a 1272-6038B DMD chips, if you need further help, please freely contact me again,

The White spots you see is the LED's thats not working you need to take it in for repairs as soon as possible otherwise youll have a blank tv soon.

That usually indicates that the optical block is going bad. That repair is usually 900-1100 dollar fix.

White spotting is caused by a defect in the optical engine. Repair should run around $600-750 from a servicer. Part number is 75006693

optical engine failure. that technology is called DLP digital light processing and it uses a device called a DMD digital micomirror device that has millions of mirrors onthe face and they independtly move and sometimes they can get stuck or not move and cause spots black or white across the entire picture. i suggest calling customer support for possible repair accomodation

<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>

It sounds like it, but I would ask a local repair shop before I spend major money.

Are they spots or dots? If they are spots then the optics are contaminates. If they are dots either white or black then you have a bad DMD chip. The cost of repair depends on who you hire to repair the set or if you do it yourself it depands who you purcahse the part from.
