I hope people still check this forum! I have had my Acer PH530 since 2007 and it has a similar problem as mrkiki911, however the Acer Support Rep agreed that my unit should not be projecting upwards as much as it is. The lamp doesn't shine through the center of the lens, but rather through the upper part of the lens - and it's getting progressively worse: a couple weeks ago, I could put the unit flat on my counter and project toward my wall, and the top of the picture just would hit the corner of the wall and the ceiling, but if I do it today, two-thirds of the picture is now on the ceiling.
1) I am given to understand that this can be corrected in Service Mode. I have figured out how to get the Service Mode Menu to come up, but the options for PC Calibration and Video Calibration are greyed-out. I've tried plugging my PC into the VGA, HDMI, and my VCR into the S-Video, Video,a and RGB ports, in hopes that this will prompt the projector into making those two options selectable (the other menu items are okay), but without successt. Does anyone know what I need to do to allow me to select these modes?
2) And what is the most recent firmware version and does anyone have a link to where it can be downloaded? Acer's website is no help.
