Optoma HD66 projector is a HD projector which comes with 1280×720 native resolution which is an old Optoma projector. I think there are lots of owner of the Optoma HD66 projector have the same problem. That is white dots on screen of this model.
As Optoma HD66 is a DLP projector which comes with a TI technology DMD chip, the chip itself will be aging after a few years of usage. When there are some white dots or black spots on your HD66 projection screen, it may come up more and more in a few weeks. I found there are some people asking if any repair center is able to repair this error or if they can repair the DMD chip. Here, I don’t thin it is a smart choice to ask the repair center or take the projector to the repair center to ask for a solution. They may cost you a few hundred dollars for repairing the white dots error. Or some repair center ever offer more than 900 Euro to fix their projector. It is really expensive to replace a new projector.
However, it is still two solution to fix your Optoma HD66 DLP projector. Too replace a new projector or replace a new projector DMD chip. There will be no more another option. You do not need to search on google if any one who can repair your original DMD Chip or any compatible product such as compatible projector lamp to replace your original. I can 100% sure here in the world, there is no one can repair it unless TI technology and there is no one who can copy the TI technology to make you a copy.
- If you are offered more than $500 to repair your original DMD chip from projector repair center, I don’t suggest you repair it. It time for you to through the projector to the garbage. Because there are new replacement projector which is better for your original Optoma HD66. Here are some new projector is about $500.
The above projector is Optoma HD141X 1080p 3D DLP Home Theater Projector is a 1080P projector with 3000 lumens brightnewss. Which sells only $549. This projector is much better than the Optoma HD66. Higher native resolution, and more brightness. Will you still want to spent thousands of dollars to repair your Optoma HD66 projector?
2. If you still want to less to repair your Optoma HD66? It would be OK. Just replace a new DMD chip is fine. The Optoma HD66 dmd Chip is $190 only. Don’t buy an used chip. Or you will have the same white dots within 1 year. A new replacement chip will let your projector work for another few years.
As I mention above, it is not a good idea to ask the repair center to help you to replace the chip, it may cost you 100-200 USD repairing fee and another $190 new DMD chip fee. If you don’t know how to replace the chip, you can follow the follow video tutorial which is created by JAIME GONALEZ
Recently, we found too many Acer X1160 projector users has the same problem of white dots error on screen. And today, I am trying to type in a post to make some tips to help them to fix the error.
First of all, we need to know the Acer X1160 is a DLP projector. The most important part for DLP projection is the DMD Chip.

And some are using 0.55 inch chip, if you get the big size of 0.65 inch chip, that will useless. So, before we sourcing a new replacement chip for Acer X1160 projector, we need to confirm that our original chip size, and native resolution.
Most of time, we suggest user to take out the Acer X1160 original dmd chip and confirm the correct part number that printed on the chip. It is the best way to confirm the correct chip. Because the manufacturer of projectors and TI company will never told the projector user which DMD chip is using in your projector. As our projector repairing partner experience, we can tell the correct chip that works for Acer X1160 DMD Chip. You can buy it at amazon DLP Projector DMD Chip for Acer X1160 to replace your old chip. There are several sellers for this chip. Some sells at $179 and some sells at $199. You can check the amazon review before making purchasing as this model is old model. There maybe some used chip in the market.

Before understanding the reason that cause the error, they tried to replace a new projector lamp. Even they tried compatible replacement projector lamp or Original OEM projector lamps, the main error can not be fix.
Actually, the white dots mostly caused by a aging projector DMD chip (Digital Mirror Device). They were trying to find the problem by searching in the internet or check for their projector manual. Unfortunately, NEC will not tell you the secret. Because if you ask them to help you repair the projector, they will charge you hundreds of dollars. If your projector is still under warranty, you are lucky to ask the supplier to offer you a free DMD Chip which can save you hundred dollars.
However, if you find out the projector white dots is caused by aging projector DMD chip, you still do not know which dmd chip fix your projector. After searching from the google or checking from your projector manual, you still did not know the correct dmd part unless you take off your projector cover and check for your used DMD chip.

How do you replace the new chip to fix the white dots errors?
It is easy to replace the new chip if you know a little tech skill on electronics. The most important to do this is you need to find out where your dmd chip located.
After taking out the projector cover, you may find a cooling plate around the projector lens. The projector DMD chip is always protect by the cooling plate. The only thing you need to do is follow the cooling plate, and take it down carefully. I suggest you open your phone cam when you take the chip out in case forgetting how to install it back or missing one of the parts.
If your projector is not NEC NP215 OR NP210, please check the projector DMD Chip list.
