Putting the emibedded grid screen on your set is easy. First download the service manual (free from eserviceinfo.com) It is compacted file and this will show U how to get into service mode. There are a lot of adjustments that can be made. I believe the convergence chips run hot on these sets and most likely U have this problem. Don't forget to check the resistors and fuses around this circuitry. Hope this helps

- Have a KP57HW40 set with bad blue crt. Is sony still covering this set for the tubes ? Your post date was 2005 or was that an error ?
Set has been to 2 service techs and both have said tubes are no longer available - whta R U guys talking about ? This set has given me and probable all customers who bought these sets a bad reputation on SONY part. I will never buy another SONY product ever. John

I am trying to determine if I have a gun focus problem before spending money
for a service call or service manuals... I am an electronic technician who
has been involved in troubleshooting/repair for 21 years.... I know enough
not to blindly tweak things.

We're replacing all the picture tubes in these at a rate of about 4 sets a
week.
Sony has a big problem with the jugs on these - they're extending warranty
coverage at least another year.

SONY has actually a modification for these sets that exhibit pulsating in
the picture and changes in tracking (I.E. colour changes). The mods include
changing the CPTs. AFAIK the mods is not for poor focus problems.

What are you trying to do?  If you don't know the answer to this question
you are likely getting in over your head and need to either get an
experienced Sony tech to help you or go through the Sony training manual and
service manuals before attempting any alignment.

Totally agreed, there are way too many parametes that your can simply foul
up by experimenting with this set. If you really want to do it then order
the service manual from SONY, When done call a SONY service tech and tell
them exactly what you did and bite the service charge bullett for them to
correct the problems. BTW if there is a problem with the set it should be
diagnosed before attempting any parametre changes via the service menue.
