I would just like to thank the community for providing such a great resource on projection tvs, its been a great help. I've scoured these forums for awhile now and haven't had any luck finding a solution to my problem, so here's hoping this post will end my misery.
The Problem: My friend gave me this tv which wasnt working at the time, but a new lamp was a quick fix. However before giving it to me he decided to try and fix it on his own. He removed the screen, and the lens
! The lens was in two parts an outer lens and inner section. Both of these were very dirty with smudges and residue. I cleaned both with a lens cleaner and replaced them hoping it didnt damage the picture quaility. Unfortunately the picture is very much out of focus, and dull looking. Now my question---
Questions: How do I adjust the lens properly? I noticed tic marks with lettering marked A+/- B+/- C+/- along the edge of the top most lens, but I have no clue how to use it. Is there a point where the inner lens needs to line up with the outer? How far in do I twist the whole piece back into the optic block?
Thoughts: I have attempted to use my naked eye to focus it in but i still feel like its lacking. I'm just hoping some kind soul has a idiot proof method of focusing it in without a costly service call. Any help would be greatly appreciated!
tldr: Lens out of focus, need to adjust it properly how do I do it aside from eyballing it? (the lens has been pulled apart into two)
