It's hard to read your post, but i'll do my best from the pictures.
It seems the horizontal screen size is a bit too large, cause the left and right parts of the screen to not match.
You can adjust the horizontal size with the 'hsize' adjustment pot. It's under the control panel usually.

If you cannot go lower, and make the screen fit horizontally, there is a jumper wire that controls this a bit:
A jumper labeled "E" connects to either CN507 ("Normal") or CN505 ("Wide"). Check how it is set up now.

If this also doesn't help.. there is a HS.LIM adjustment on the main chassis, which is usually glued in place.
You can adjust this one if you clean it up, but be VERY gentle with it!!!
