Have the tech show you that he has a Sony manual, show you the procedure and
explain what he is donig as he goes through it. That way you will know if
he knows what he is doing and that he is using the correct procedure. If he
can't or won't, youare dealing with the wrong servicer.

IMO it is completely reasonable for you to have procedures applied to your
set of this nature explained and demonstrated. If your questioning of his
work is of a nature that it requires extra time to complete the job,
however, you should expect to pay a bit more. It should not take any longer
to show you what he is doing, if you are reasonable and have some
understanding of electronics.

You also need to make sure that he is Sony authorized and is using the right
part and has all of the service bulletins on your set.

I have a one year old projection tv that had to have the focus
block replaced. The block has 6 knobs, 3 to focus each color and 3 for
what I think is the amount of each color or something similar. The
service tech came over and installed it by copying the settings on the
old block for the color adjustment and focusing it by turning all the
color down with the remote and focusing a black and white picture.
This does not seem like the correct procedure. After he left I reset
all the modes of the tv, eg Movie, Pro, Standard. The color is too
strong on all these standard setting and the picture just looks like
crap. I was thinking he would hookup some electronics to take
measurements or something. Anyway 2 weeks later the colors on the tv
are all messed up. Lots of green terrible picture. We have another
call in for service and I would like to know what the correct
procedure is.

Does anyone know what the Sony service manual states?
