Tips from Dennis O'Connor: Tip is
for his Toshiba set but your set may have parameters that is similar to yours.
I haven't seen this suggested before, so here it is: after convergence and geometry is
perfect, adjust the horizontal and vertical blanking settings until they start to blank
out parts of the visible screen. Then back off one notch, and voila! less unused light
being projected inside the screen.
This should eliminate the "seeing reflections from scrolling credits before the
credits appear on the screen" problem. This should also be done for all modes using
the Toshiba service mode settings (VBKH/VBKL/BLKH/BLKL).
Now my question: On my Toshiba TW56X81 I seem to be able to get a very good top/bottom
blanking setting using the VBKH/VBKL service mode setting. I can adjust in 1 line
increments!
But BLKH and BLKL seem to adjust top/bottom blanking too, not left/right like I'd
expected. Is there a left/right blanking setting?
If not, I'd thought in the long term I'd look into doing some physical blanking -
little adjustable shutters near the lenses to deflect any unwanted light. I may do this
anyway to reduce stray light, but the electrical adjustment is quick-n-dirty. |
