We will see how it goes. I plan to use it for a week or two, the 15 pixels that are currently dead don't keep me from using it to play the XBOX, so it isn't a big deal. I don't know if I could watch a movie on it like that as they are bright white pixels. I am buying a new TV in a few days though, so I am not terribly worried about it. I can definitely change it myself which is awesome, and I am going to find out if the DMD chip thermal paste was the issue.
If anyone is interested, you can probably put a PC fan on the heat sink pretty easily. It is completely open on one end of it.
Do you think it is the DMD chip itself or the poor performing heat removal? If my pixels crapping out stops, then I am going to assume the DMD chip itself isn't the problem and I will definitely change it out with a new one using the arctic silver 5. If you use AS5, then you might want to watch a movie on all high lamp settings after installation. It does have to cure somewhat, but is probably much better than the thermal pad right off the bat. It has to cycle cold and hot a few times before maximum heat transfer. It does, however, do better uncured than thermal pads/tapes.
Here is a chart of common PC thermal pastes. You will see Arctic Silver is pretty awesome. However, there are others that might be cheaper and/or better than AS5 in this usage. I used it because I trust it to be better than the pad and I have enough to last me forever.
I considered ditching the projector because I saw a HD67 unopened in the box for 450 locally.
I would of still ripped this one apart. After I checked and saw I only had 900 hours on my bulb and all of that at theater black I decided to salvage it. It is almost new still!
When I take it apart next time I will definitely take pictures.
