Hello there,

I recent bought a VIEWSONIC PJD7822HDL projector (Open boxed) and sometimes, randomaly, the projection turns green for about 1s.
i search and someone aid to turn on High Altitude Mode to make the fan speeds up. This reduced the amount of times the problem occurs but still, sometimes the green projection shows again.
My questions are:

- What is the real problem and how can i fix it?
- Can i improve the fan to other more powerfull in therms of airflow?

Thanks for the help (im a n00b in DLP projectors and love to learn more)
