Omni T6833NF TV Fault

Hi All,
TV has a raster but it pulls in in the middle of both sides. Have
checked out most of the caps with the ESR tester and the transistors and
diodes with my multimeter. I get some text on the screen FAV so is
displaying the internal generator OK. I don't have a circuit so what
should I try next?
Regards,
Paul. ()

 

It sounds like a pincushion fault. E-W correction is usually (?)
applied by coupling a portion of the vertical parabola into the
horizontal output. Look for a part of the circuit where the H and V
sections meet, eg a small transformer, E-W correction IC. Otherwise
locate the datasheets for the major components, eg the jungle IC, and
study their application circuits.
