Service Manual
Go Back To Categories
(1) Is a factory service manual available? If so, where/how much? You can order/buy
the Service Manual for the KF-50XBR800/KF-60XBR800 for $29 + tax + $3.50 s&h
from Sony (877) 865-SONY (7669)
(2) How is the Service Menu arranged?
Category..............Item No. ...........................Data.................Model
Item........................................................................Input Signal
(3) Is there any settings in the service menu that can help improve the 480p PQ? I
would guess it is your DVD player since many people are seeing excellent images with
progressive and interlaced inputs. I would suggest you get a reference quality player like
a Sony DVP-S9000 or DVP-S7000 to go with this excellent RPTV.
(4) Are you aware of any setting in the service menu that can chance the rotation of
the image. By "rotation" I mean one corner of the picture appears to be lower then
the opposite one? Unfortunately, the XBR geometry adjustments that would normally
fix what you are seeing do not work on this TV. Your only hope is if there is some way to
adjust the projector, but I don't know how. I have been trying to get a manual for the
projector part of the television, but have not had any luck so far.
(5) Is there a factory reset function if you mess up to get everything back to default?
Yes and no. There is a function, but I don't have the guts to use it. I have read about many
problems with this function.
(6) Service Manual does not have explanations, how did you get started with this
manual to figure out what these letters mean? Actually the manual is even worse than
you can see. It totally excludes circuit board "C" which has the optical drive circuitry. To
me its main value is that it shows how the memory is organized and it provides a good
place to record all the values I am changing. Many people have struggled understanding
the memory structure without the manual. I read CRT XBR threads on how they tweaked
their sets. Searched the web for info on key IC's. I received some help from Bill Cushman
about things to look for. I also experimented with chips that looked like they would do
what I wanted. Many of these attempts were futile. This required many hours with the TV
and test images.
(7) It seems that the tweaking are not only input dependent (in the case of video 5-7)
but also signal dependent (480i 480p 720p 1080i). Is this correct or am I reading this
incorrectly from the tables? Yes that is correct on some of the tweaks. The manual
makes it a little more clear how this works.
