Seen way too many or the RCA devices where the specific symptom (Slight
shadow diagonal across the raster) is caused by defects within the Light
Engine Assembly. FWIW!

Wouldn't a displaced mirror cause image alignment and maybe ghosting
overlap?
I don't get either of this. there is no ghosting and no alignment
problems..
Just the unaffected area's are darker than they should be while the
brighter band looks more to a normal intensity of the video..
But i'll consider that as I get ready to install a new lamp, It's about
time for a new lamp any ways. I need to clean it out. It wouldn't
surprise me to find a load of dust in there.



Not necessarily, it depends on which mirror.
