Model # AV-48WP30, it was picked by another shop, & the large stand up
module (tin can type), that one of the plugs from the little
convergence board goes to, has been out of the set,
& put back with no screws, & MAY be bad, even though they don't
commonly go. It had bad convergence. I replaced the stk 392-110
convergence IC's, & resistors. It convergences good, but the overall
pix is shaped wrong, like bad pincushioning. Going from left to right
the scan is up & down, both on top & bottom. I can adjust all service
menu adjustments, but can't get it square. .Anyone see this problem?
Dani.

Basically have to reset the geometry, aka pcc, heighth, width, etc and then
do all the registration. Can be a bit fustrating and time consuming. There
are other adjustments that yu will need to make and/or repair the pcc
circuits also.
