I recently acquired a rather heavy Trinitron tv and although the picture is decent, it seems to have some issues. I'd like to see if anyone here has experience with these types of tv's and if this one can be adjusted to possibly improve the picture.
What I'm noticing is some color and/or possibly (I'm still learning about CRT's) some dynamic convergence issues. I've tried to read any information I can find about this subject and I have read through the service manual for this model. I'd really appreciate some advice so that I don't end up damaging the unit.
The most noticeable (to me) issue here is the top left corner. It seems to be a bit distorted and is slightly darker than the rest of the screen. Otherwise, it seems like there is a little bit of adjustment that could probably be made along the bottom but its not really that bad.
I've gone through the service menu but I didn't want to go nuts on settings before I have a better grasp of what I'm trying to do.
For the following I used a Wii via composite to display the patterns from 240p test suite, and an SNES via component for game shots.

Thanks in advance for any advice or information that can be offered, even if it's just saying that this unit is junk.
