With the contrast down, looking into the lenses of my ECP 4100 I see that the raster is not centered vertically - in fact, it's bumped up against some metal clip thing at the top (bottom now - ceiling mounted) of all three tubes, which actually blocks some of the scan. (You can see the shadow...)
What is the adjustment to center the rasters vertically?
I'm afaid the answer is going to be "there is no verticle dc offset adjustment". Then if so, how do I fix the problem? It's as if 1/3 of each tubes phosphor isnt being used, because the raster's all jammed down at the bottom. Not that moving this would change the %, but I somehow think it best to have the raster at least somewhat centered both vertically and horizontally.
Thank-you for any help of suggestions.
