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,

It is $50 on cdrom from tritronicsinc.com

You will need to contact them with the model number directly so they
can look up the chassis series that contains the service manual. I
think it may be listed along with the 27af41 but you need to make sure
before you order it.

You might find that there is no horizontal or pin adjustments on that
model. It is a lower end tv set in a smaller size and most 27" size tv
sets no longer have any real geometry adjustments in the H direction.

Thanks. I had already called Tritronics, spoke to several different
people there, and was told that not only didn't they have a service
manual for the 27AF45, it didn't even have a Toshiba part number. Same
story at the other parts places and repair centers. No one mentioned a
CD ROM.

How would I find out whether there are such adjustments without having a
service manual?

On some models like this one there is a factory modification. Are both
sides of the edge of the picture having torn edges, as opposed to
smooth edges? If so E-Mail me, & I'll dig out the factory mod sheet.
The edges are distorted & the pic isn't quite stable. Dani.
