I pulled the optics out of a defunct projection TV, and I noticed the lenses do not have a flat lense to mound the LCD. I played with the optics, and since the lense is cureved, the Picture projected fine, but the focus is bad on the edges and corners, but fine in the middle, How can I fix this?
Projection Lense : Delta 21
here is how the optics were put together:
went from a 5" CRT ---Bowl shaped lens --- Projecter Assembly(delta 21).
I didnt use the bowl-shaped lense, but what is it for?
I didnt use it because it is not flat either. its like the lense on the delta IV, but the back is not flat, its a bowl, but same lens.
