I would like to make (slight) adjustments to the horizontal width and
pincushion distortion on my Toshiba TV, model 27AF45. Does anyone know
if this can be done via a service mode menu? If so, how do I access the
service mode.

FYI, all of my attempts to obtain a service manual for this TV from
Toshiba customer service, their authorized service centers, and their
authorized parts distributers resulted in them saying that no service
manual was available. Surely, there must be one, no?

Thanks,
