This is probably a long shot here... but I'm trying to see if it's possible to bypass the Epson Auto Iris found it a lot of their 720p projectors (such as their brightlink series and so forth). The auto iris has 7 wires coming from it, 4 for the motor, 3 for the movement sensor. I know Epson documentation is nearly impossible to find, but never hurts to try? lol
I just want to see if I can trick the projector into thinking the auto iris is "fine" at startup, which is when the failure occurs, and prevents the projector from even working. I've had enough of these things come in that it would be nice to have a solution to them. bypassing the iris would be great if possible, since in these projectors it seems quite useless, and doesn't really have any effect on the image brightness or contrast when it is working.
Give me a couple model numbers of some of these with that auto iris and I'll see if I can dig something up.
Home Cinema 705HD
Home Cinema 710HD
Just to name a few And from what I've found so far just from having these around, the iris design is pretty much identical between all the models. I don't think the 1080p projectors Epson makes use the same iris system, so those wont be of any help. The iris system in the projectors above is just 2 pieces of metal that open or close, not like some of the more elaborate designs.
Well I found an Epson service manual that has the auto iris. With that said, this manual is a total waste. No schematics, no wiring diagrams and no connector info.. So it is no help at all.
Do you have an Epson with auto iris there that you can test probe that connector and get the readings during startup and running?
Yes I do, I have 3 brightink projectors here that have the issue, a 4th is on its way back as of today >_< . It really blows because a projector as new as these shouldn't be failing this early (with a common problem between them all)
Anyway I can test it, but I wanted to ask, would me sending you one to mess with help? I have no problem doing that if you're up for it, and im not in a rush to have you get it done. These projectors are worth $300-$1000+ depending on the model all day, that's why I've been rather persistent on getting them going.
I would be more than willing to make it worth your while if you could get one of these things up and running, and also share your findings if anything is at all possible?
