This projector was brought by a friend who needed it checked, I powered the machine and this is what I saw on the screen.
A technician is more or less like a medical doctor but medical doctors have added advantage since human being can talk and explain how they are feeling.
In electronics we rely on symptoms and error codes if
generated, in the case at hand we have “Auto iris error” code.
From the above error code, I did some research and noted the
error is usually caused by problem with Auto Iris Assy.
To access this module you need to open up the machine below,Epson projector model EB-S02
After removing the cover
Motherboard now removed
Remove the optical engine Ass.
Auto Iris assembly is part of optical engine.
In human being,”The function of the iris in the eye is to control the amount of light that reaches the retina. It does this by changing the size of the pupil, the transparent window that allows light into the eye's interior.
The same case applies to
projector auto Iris and therefore if there is an error on this assembly the
Auto iris error will presents.
After accessing this module I scanned
it and noted one of the blades was loose and hence not closing well and hence
the error.
I tightened the small bolts
and re-installed it back to the optical engine assembly and after powering it
up the error was gone.
Thank up guys
See you in the next class.
