Hello, Projectors and DLP TV's share identical errors- the Lamp chamber has a micro switch, and the lamp cover has a micro switch located right behind it. Both are wired in series. Either switch being OPEN or having FAILED will trigger the errors. That said- Why is it that you think the errors are false please?
Also did you just recently replace this lamp? If not when did the issue occur?
If so, where did you purchase the lamp from and for how much?
Thanks. Please elaborate. You're saying the error came up after you just swapped the lamp yes?
If so, do you have the old lamp there and as a TEST can you put it back in the projector just to see if those error lights go away.
Sorry, but I'm also curious HOW exactly you "checked" the switches???
First- the OEM lamp for this projector (Osram) runs for about $175- so the one you have is a copy and the most common cause of this error.
Secondly, to test the switches, you actually need a multi-meter to test for continuity across the contacts both when the switches are open and closed- so are you sure you did that?
Please try the old lamp test as this will shed much more light on this problem. Let me know what happens.
