I took some pictures:

I tried adjusting in service mode. I was able to fill up the entire
screen with image but bowing doesn't go away. I noticed that "H TRPZ"
has very little effect on the screen.

Any comments or suggestion will be greatly appreciated.

I guess that is the horiz trapezoid adjustment. Keep at it you'll figure
it out. Might help to have some technical literature on the set.
