Hello,

I have Sony PVM-2950 with pincushion problem.
The image bows toward the center of the screen from both top and
bottom. I believe this symptom is called "horizontal" or "north-
south" pincushion problem.
I tired to adjust it in service mode, but I was unable to control the
amount of bowing at top and bottom of the screen. I can control
barrel shaped pincushion (east-west) but it does nothing on top and
bottom of the screen.

Is there anything that I can adjust horizontal pincushion without
opening the set?
Could somebody please give me a clue on what is causing this problem
and where and what to look for?
I have a service manual but because I am not an expert, only thing I
can think of is some failure in VC, DX, or part of A board.

This is first time I'm posting, so please let me know if I'm doing
something wrong.
I would appreciate any response..
