Look like pincushion problem to me. Pincushion problem always bent by the side. If it's flyback, most probably no pictute or arching.

Second possibility could by the deflection yoke, the yoke controls the vertical and horizontal of the tv. If it kapuk, it will affectthe v-h section of the tv. All kind of weird angle.

You cannot just subtitutes with 29" flyback trans. It wouldn't work. You have to get the same part number to replace it. If you friend keep on modify it with diffrent flyback, end of the day it will damage more components in your tv.

Did you contact Samsung Malaysia direct for the part? How old is your TV? If Samsung said the part has been discon., than to get the part is almost impossible.

You also might want to check with Pasar Road shop.

Hope this helps
