I don't think it's the vertical chip, some voltages seem to be very hi,
like that 52V on pin 3, Is there any resistor on the yoke return?,
also check diodes or zeners in vertical circuit. Both vertical winding
on the yoke have same resistance?
I'm giving you some ideas, good luck

I have a Magnavox TP3285-C129 with a chassis 32K800-7591 made in 2001.
The vertical is off center to the top. Getting into the SAM menu lets me
adust the ver-shift parameter from 0 to 63 with 63 being the best but
the picture is still too high. The pix does move as I adjust it and the
height appears good. The vertical output (STV9379F) has the following DC
voltages:
1 +0.6v
2 +12v
3 +52v
4 -13v
5 +1.2v
6 +12v
7 +0.6
I do not have a service manual or a new output chip. Could the output IC
be causing this? =A0 What else could cause it? Thanks for your reply.
