Default SONY KP57HW40 what is the focus block install procedure?

This job is a "shop job",doing it in the home is not a very good practice.

The Tech called and spoke with the wife. After answering his questions
about the problems with the color he said that the picture tubes
needed to be replaced. No service call or anyting. That SONY extended
the manufactures warranty on TV's that had to have the focus block
replaced. So the procedure is covered under warranty. We did buy the
extended 3 year warranty too. He said it was a 4 hour job.

Does anyone know what the procedure for replacing picture tubes?
Should this guy come with any electronic measuring devices to
install/Focus these tubes?

Anyone know where I can get the service manual for this set? KP57HW40

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?
