Here it is: the shut down cycle will run the cooling fan as long as necessary based on a thermal sensor so there is no set time for this. Put another way, there is a thermal sensor that determines the the fan run time based on temperature. I am a firm believer that cooling lamp filaments too fast is a bad thing. Let that metal cool slowly so as not to stress it. I am also a firm believer in LED lit DLP but we are still waiting for cost effective solutions for that.
Again, I have some other info that needs to be clarified but I am told that the 9500 has a 6 segment wheel that spins at 7200 rpms at 2x. Sound like a hard drive motor to anyone? It also spins at 9000rpms for 3x and that is at PAL 50hz. Not sure what that means or even if I believe the wheel is 2x during normal ops but it is a DC2 chip. Some of this makes sense since when activating 3D it sounds like a hard drive spinning up. As for the wheel, I got no solid answer except it was a 6 segment one which leads me to believe it is RGBRGB. I have a few more answers that were sent back for clarification so no need to talk about them now.
So they are answering all of my questions or forwarding the ones they cannot answer. I am happy with that as they are responsive. Let's see where it goes. Again, most of this is fluff for me but I am tired of hearing about complaints of this unit where they are simply returned instead of trying the support channel. None of this will be fixed that way and yes I told them about the 3D 720 gaming tearing issue and asked about the glasses. The glasses issue was not an issue for me though they offered a PN and vendor. I figured others beating them up had this covered.
The explanation of the "shut down" issue you describe (the fan running for X amount of time, depending on lamp temperature, after shutting down the PJ) makes sense and, in fact, makes a lot more sense that having a fan running for a static amount of time without regard to other issues. I still don't fully understand why it's important to have the bulb cool down quickly when it's very hot and then use a normal cooling process, but I can certainly believe this is important.
I never start arguments on forums like this and think that most disagreements are a result of misunderstandings and different needs or expectations on the part of the participants.
I have returned a couple of Acer projectors, but have only done so after going through appropriate channels (Acer Tier 2 at the minimum) in order to confirm a hardware problem with the projector before the return. The first time I went through a return, it was because the 2D to 3D conversion wasn't working properly (plus it was $200 less over President's Day weekend). The next unit had a lot of shut down (during viewing) issues and, in addition, the HDMI 1.4a ports clearly didn't fall within the spec. I tested this in multiple ways using my first PJ and my existing PJ (Sanyo....1.3 compliant) to confirm the problem.
In all cases, these issues were documented by Acer and I was given a case number confirming the problem. I don't think I'm being referred to as someone how just returned the PJ instead of working through support channels (or complaining for that matter), but wanted to make it clear that:
A - I REALLY like this projector
B - I spoke with Acer to confirm hardware problems and was more than willing to go through any suggested troubleshooting procedures.
The bottom line is that I have had no problems with my current projector and am convinced there were hardware issues with the returned items. I originally bought a brand new projector and wanted to make sure it was operating properly. I was convinced the first two were defective and wanted a new rather than repaired model (though repairs with engineering updates can be superior to OEM models....something to keep in mind).
This is a great thread with people who are willing to go out of their way to help others. I genuinely appreciate everyone's contributions.
