Hello,
I have a projector that is over 1.5 years old and the lamp is new, but here’s the problem: a white spot has appeared on the screen, then 2, 3, 4, 5, 6, and more, and there are some black spots as well. I did a complete cleaning, as much as I could, and I didn't want to mess with everything too much. It’s an Optoma ES522, and could you tell me where this might be coming from?
Thank you.

After two years, my Acer projector started displaying white spots.
I disassembled the beast and found the references for the faulty DMD chip (the micro mirrors).
In 20 days, the new chip arrived from China and for around €140 and 1 hour of work, without any soldering (everything just clips off), I have a perfect image again.
I made a PDF document summarizing the different steps.

Hello, I've had an Acer P1266 for a year and a half, and the lamp has about 1700 hours out of the 4000 promised by the manufacturer. I've also noticed the appearance of white spots over the past few days...
How can I make them disappear?
Thank you

Acer review.
I myself had this problem of a white spot on my Acer X110 projector purchased in June 2009.
I scoured the forums to find out how to fix it... The white spots appeared in the summer of 2014... I wasn't expecting much from the current 2-year warranty and therefore knew that I would have to pay out of pocket...
Well... little advice... and, for once, when something is remarkable, it needs to be noted: don't bother spending even a penny if you have an Acer less than 5 years old showing these symptoms!
Indeed, I read on a forum that Acer guarantees the DMD chips, the source of the white pixels, for 5 years!!
All you need to do is go to the Acer website:
http://customercare.acer-euro.com/customerselfservice/
Don't bother looking for your old invoice to justify the purchase date: all you need to do is enter the device's serial number, state your problem... from the product serial number, they retrieve all the information, and most importantly, the purchase date!
From there, the Acer process is both very well-oiled and super efficient!! (I mean, it worked for me, and evidently, as I read, it has worked for others as well)
You will receive an email confirming (which was my case) that Acer is taking care of your equipment for inspection: they send it to you via prepaid chronopost, all you have to do is pack it carefully and send it.
If the repair is indeed that (DMD chip), and it was in my case, everything goes very quickly: sent last Thursday, they received it Friday morning, took charge of it Friday afternoon, shipped it back Monday morning, and I received my projector with a "like new" image by this Tuesday noon! What more could one ask for?
In the event that the problem is not due to the DMD: Acer will issue a paid estimate, however...
For once that a customer service is efficient, I wanted to share this...

It indeed seems to be the disease of DLP projectors, I have an Optoma DS 309 that has 400 hours of operation and after contacting Optoma's customer service, the cost of diagnosis and repair is the same as the price of a new one.
Hello,
I had the same problem with an Optoma ES 522, which was already... 6 years old.
Several white spots, then black spots. I followed Eric's tutorial (THANK YOU!) and ordered the DMD chip on Amazon (DLP Projector DMD Board Chip 8060-6038B 8060-6039B 8060-6138B For Optoma Infocus Samsung LG Nec PROJECTORS). For the ES 522, it's the 8060-6038B chip.
It arrived after 3 weeks.
Reassembled everything and it works perfectly!! Just like the first day...
Thanks to Eric's tutorial which motivated me to do it.
Good luck!

Same phenomenon with an Optoma EP 726 aged 1 year and 4 months. It is still under warranty, so I will have it assessed. I will keep you updated.
What was the result of the cleaning? Any improvement or not?

Hello, could you please provide me with the quotation amount for replacing the DMD chip of the Acer X1160 projector? I was given this projector which is over 5 years old, so it is no longer under warranty. I contacted Acer's customer service and they told me that I would need to pay 40 euros for the diagnosis. If it is repaired, this amount will be deducted from the invoice.
Thank you.
Thank you.
thank you very much !!!!!
after receiving the DMD chip, I began reassembling it.... by applying thermal paste... but it wouldn't power back on.
so I started over, checking all the connections... but still the same problem: red LED after powering on and during startup a blue LED, but two red lights come on, "lamp" & "temp"
if anyone has any ideas to help me, thank you!!!!
On mine, after changing the chip, a quick test worked.
The next day, a blue LED, but no power lamp, no image.
I took everything apart, put it back together and it worked. Since then, no problems.
I know there are different sensors, if they are open or poorly reassembled, it refused to turn on.
Any ideas: are the chips identical?
Put the old one back (don’t waste any paste here) and check if the image comes back.
Be very meticulous in reassembling, in the connections but also in the casing of the video.
After a failed test, unplug for a while and then try again.
Eric.
