After the last maintenance (where I also found loose parts) I also finally hooked up the projector to our HTPC via HDMI instead of VGA. However, I then noticed, that at the left edge of every white pixel on dark background, there is a red shadow, and on the right side there is a blue shadow. As if the red, green and blue LCDs weren't aligned properly. I have added some pictures to show what I mean:



It's not noticable from more than 1 or 2 meters away. In the past I always attributed this to signal run-length differences in the ~18m VGA cable, but that's not the cause now.

But may be this is normal anyway? I have no idea.

I would try hooking it up to the VGA port and see if the problem persists. I would also check the scan rate in the computers display properties menu.

There could be a scan rate mismatch between the source and the HDMI port on the projector.

BTW - THESE are just off the cuff ideas so good luck.
