Today I got my projector back from the service center. They didn't replace it, but "repair" it (whatever this means). Indeed it was the same unit (serial number), firmware updated to v1.09. Lens shift still sucks (adjusting one changes the other axis, etc.) and so it took me about 30 minutes to adjust everything properly. During that time, the menu of the projector was displayed, so that I could adjust the focus.
After setting the unit up, I immediately opened a dark gray bitmap image to see if the burn in of the black bars was gone. And indeed it was.
HOWEVER: the menu, which was just displayed for 30 minutes was clearly burned in! I thought, oh my god, what's that supposed to be now? So I started a movie to see if it would go away. It didn't! The menu even was visible in dark scenes of the movie!
After another 20-30 minutes, I displayed the gray background again to see how the burn in developed. Guess what: the menu still was visible and furthermore the black bars burn in was also back!
I've attached a photo. You can not only see the black bars and the menu structure, but you can even read the menu items! Horrible! Also, some parts of a window on the computer desktop are visible. Burned in in just a few minutes.
So this is what Epson calls "repair"? Obviously, the panels in my unit are broken and they didn't repair them, but somehow just cleared the original burn in. But everything (and more) comes back after just a few minutes...
What should I do now?
