Trinitron geometry problem, tried everything in SM to fix it

[Qwerty 9999]

Hi everyone, I'll try to explain everything as best as I could, not that easy since english is not my first language.

I have this problem on my Trinitron kv-29fq65e: http://i.imgur.com/5KmsaBth.jpg

In short, the left half of the screen bows down. This happened AFTER I messed up in service mode, now I literally tried every setting to fix it and NOTHING works. I found the 29fq65b service manual (which says is compatible with 29fq65e, same chassis as well), and some service mode entries listed in this manual are missing in my service mode.

I'd prefer not opening the tv.

Will changing model in "model settings" be any useful? Already tried setting "kv-29fx65" and "kv-29fq70" (or something similar) and nothing happened.
