So I sent my HD81 back in for repair last Tuesday. It would go into this weird mode where the color wheel would make a really loud noise as if it was suddenly spinning much faster. The image would be visible but the colors would be all screwy and there would be weird artifacts occasionally. This 'mode' occured intermittently for several months before I sent it in (delayed for fear of receiving back an unfixed unit.)
I can relate to a number of the issues that people have had with this projector. As it is so obvious to me that many of these are inherent to the design I have lived with these issues and tried to enjoy the excellent image that the projector displays when it is working. I have only sent the projector in when it completely stopped working - this is the second time in approximately 15 months of ownership.
On the suggestion of forum members, I have emailed Warren Pierce in an effort to try and ensure my worst problems with this projector are resolved. First, and foremost, the color wheel issue but secondly an issue with overheating. Ever since I sent my projector in the first time I have been unable to run the projector in normal fan mode without frequent shutdowns. I was initially running C04 and they upgraded me to C08 during the repair. I have been enduring the projector in 'high-altitude' mode ever since. This really sucks as the projector is right over our heads and as owners here know - these things are very loud. I think it is unacceptable that it is necessary to run the projector in this loud mode to prevent (err, reduce) shutdowns. Oh, and BTW I am at ~500 feet elevation, the room temperature is kept under 70 degrees fahrenheit at all times, and the projector has unrestricted ventilation on all sides. Furthermore, high-altitude mode doesn't eliminate shutdowns entirely, it just makes them far more tolerable.
I should note that I have a very early projector. I bought the projector from AV science and it was from the first batch they received. I have heard some of the early boards had overheating issues?
I fear that they will repair the color wheel issue but not fix the high-altitude mode issue. Or even worse, the projector will work for them and they will do nothing. This would majorly suck as each time I send it in is 2+ weeks without a projector and $100 in shipping.
They have had the unit for several days now and I am going to send a follow up email to Warren.
Anyone who has had similar issues please comment on what was done to resolve the issue (if you know) and what I should request be done. Any other suggestions are appreciated. It would be really great if this thing would just work like it is supposed to as it would shut down a major stream of c**p that I get from the wife.
