It sounds like you may (not likely) have a different uPC in this set,
but this would be an unusual part to change for your problem
description. Or they may have changed something in the service setup
(more likely) for the feature type.

Many parts of the setup software is very difficult for a tech who is
not properly trained or very experienced with this type of model
series.

When changing anything that has to do with the firmware or uPC, if
this is what he did, it is very important he used the exact origional
type, and not put in something similiar. When working in the uPC area,
the setup may have to be redone. This requires the proper test
facilities, and knowledge base for the model type.

This is why I tell people that they should normaly send their sets to
the factory authorised service rep, if they are not sure about the
standard service shop. These sets are very difficult to service and
setup, and many of the problems are a challange for the most
experienced techs.

What the tech will need is the exact origional service manual for this
series of set, and go through the setups for the options, and make
sure that they are set right. Any components changed that deal with
the firmware in the set must be verified to be correct.

As for changing parts in the video path, this usualy has nothing to do
with the pin or scan problems, unless you also had video problems as
well. Since I did not diagnose the set, it would not be right for me
to comment on any part of the required service performed. I would only
be able to comment on probabilities of circumstances.

I had a Sony KV-32XBR45 (32" XBR) television that developed video problems
(it was jittering and pulsating between hourglass and pincushion) and I
recently had it fixed. Now that I have it back, I noticed that several
features are missing such as (1) side-by-side picture (alternative to
PIP...PIP still works tho), (2) Freeze picture doesn't function, (3) PIP
has 2 size settings instead of 3, (4) The "Display" button on the remote
just cycles between showing time/station and not showing time/station. It
used to also cycle through showing closed caption and turning External Data
Service on.(5)...lots of other little things.

The repair shop indicated power supply problem and also damaged video
drivers. Seemed reasonable. But, given the missing features, it sure seems
to me there's in new logic board in the TV. So, my first question, is there
video circuitry along with logic circuitry on one board in this TV? (In
other words, is it reasonable that the logic board would have to be swapped
to fix a video problem?)

My second question is, does anyone recognize the feature differences? My
repair shops appears to just have ordered a replacement board from some
non-Sony source (who claims they shipped him the right parts). I'm trying
to help the repair shop identify exactly which board they did get instead
of what they should have gotten.

Or....is this really the right board and somehow has old software flashed
into it (or maybe even has a configuration setting set wrong that can be
easily corrected)?

Would appreciate any help anyone could offer.

It is quite possible that either the Eeprom was replaced during this
repair and not set up correctly or the Eeprom was corrupted due to a
spike or surge at the time of powersupply failure.This component
contains settings for color,geometry,audio and various other
stuff.There are some settings that tell the set what model it is.If
these settings are wrong for the specific model,you bcan end up with
missing features,features that work different or menu options for
features that your set doesn't have.All this is setup with a hidden
service menu wich requires the factory service manual to obtain the
correct settings.You may need to have it set up correctly,or the
Eeprom will need to be replaced and then setup afterwards.
This is not normally a job for the do it yourself type because you can
create other problems and or cause damage.The info that appears on the
screen is not self explanatory either.
