Hi
I have problem with my NEC MT800G LCD projector, the picture are
"distorted". No fault with the convergence, it seems to be a problem
with the "RGB" signal to the LCD panels. The symptom is (I feed with a
grid pattern) that some of the lines (vertical) are ok but some are
the colors is out of "focus" (like convergence fault). If I change the
width of the picture the fault moves to another line.
I think that it could some problem with the video board (SAA7110A +
7192A).
Can somebody help me out with this or know where I can find a
schematic? |
