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.
