    I was having this issue exactly.

    I don't know where you're located, but I was able to find a replacement DMD board for the Acer H5360 from an electronics store in California.

    First I talked to Acer about repairing the projector, which was out of warranty, and they said it would be a minimum of $199 to make the repair, plus shipping. I asked if I could just buy the DMD board from them directly, but she said no. I asked for the part number, and she did give that to me:

    DMD Board: 55.K010H.003

    I contacted a local projector repair shop and told him what the problem was, and he quoted me $195 for labor, plus the cost of the DMD chip and taxes. I asked if I could buy the DMD board directly from him, and he said no, but gave me the phone number to his parts supplier, Andrews Electronics in Santa Clarita, CA.

    I called them and asked for the part. It was a special order item which meant they had to order it from the manufacturer and it would take at least 2 weeks to ship. The DMD board itself was $9.47, and then $9.95 shipping, plus tax, and I was on my way with a grand total of $21.12.

    I found a service manual for my projector online and will make the repair myself.

    Just wanted to share my experience because I had a hell of a time tracking down this part and there weren't any forums really helping me get to the bottom of it. I also didn't accept the price tag of the repair because it was half the cost of a new projector for a part that was only $10.

    Hope this helps someone.  TI clearly offers a 5-year warranty on this part, but Acer only offers a 1-year warranty. Really bad service and policy.

    Hi,

     

    I've started experiencing exactly the issue mentioned on the above link. Last week I only had one or two dead white pixels on my H5360 and now I have more than 40!

     

    It looks like a design flaw to me, it is way too rare that everyone started having the same issue at the same time.

     

    After doing some research I came to the conclusion that the problem resides on the DMD (and so I ended up here), but my question is, which part needs to be replaced in order to fix these dots? The DMD chip or the DMD board? Both maybe?

     

    The DMD board you mentioned before (55.K010H.003) seems to be quite common and cheap, here in the UK comes around £15 from several local dealers. But when it comes to the DMD chip it a bit more expensive and hard to find. 

     

    Anyway, I think I'll give it a go, I'll have to take the projector apart anyway, many thanks for your post!

     caseysousa So did you go throgh with the repair yourself and was it just the board? Did it fix it for you?

    No. The DMD board was really cheap because it was just the board, and not the chip. The chip is what fails and has the little mirrors on. I was under the impression that the board would contain the chip also, but it did not.

    I searched for a supplier to sell just the chip, and found three. All three suppliers were selling the chip for over $400. At that price, it wouldn't be worth it because a brand-new projector was only $430.

    Hope that helps.
