Topic:   ViewSonic PJD5223 Won't Hold Keystone Settings

We have quite a few of these projectors in our classrooms but one in particular is giving me issues. It is ceiling mounted and, being that the projector is not perpendicular with the screen, I needed to adjust the keystone to make the image fit onto the whiteboard. The problem is the projector doesn't hold the keystone setting when powered off. Also, when coming out of Blank mode (video mute), the keystone also resets itself. It can be re-adjusted but the settings don't stay which annoys the teacher (and me as well) that she has to reset the keystone every time she wants to use the projector. I tried performing a hard reset on the projector which didn't help. Any help is greatly appreciated. Thank you.
