I've been searching like mad to get information on my Sony Television -
Model KV-2063R. Sony's site
comes up pretty much empty on the model alone - it's like it was never made.
A label inside the television
indicates the chassis number as SCC-A50E-A - Manufactured April, 1989 San
Diego.

I require (if at all possible), information on the Bad solder connections
(relative to IF and AFC modules - and
any others I may not be aware of). Originally had a link for a diagram (and
related info) on which joints to check -
can no longer find the link. Searches have come up with everything but what
I need - including looking over many
pages in http://www.repairfaq.org/.

Also, needed are schematics for this (and subsequent) chassis in order to
upgrade the unit for stereo. All required
connections are in place internally but the components required were omitted
(obviously) on the mono model(s).

Info may be emailed to me directly:

Any help anybody can provide would be appreciated. This is (was) a great TV
and hopefully will be again, soon.

Regards,
Rob

I've repaired many of these or similar TVs.
The IF module is the silver metalcan next to the tuner. Open it up and
solder all of the coils and the grounds to the case around the edges.
This fixaes 90 % of the tuning problems with this type of set.
To find the coils, open both sides of the can, or unsolder the grounds
and slide the board out of the can depending on the particular design,
and look for the small silver cubes on nthe component side. Never
adjust the coils. You will never get them back where they belong
without some very specialized equipment that no one really uses anymore.

As far as changing a mono TV to stereo...
You would need the schematics of an identical chassis which has been
factory built with stereo to compare to the mono set's schematic and
make the necessary adjustments. This isn't too easy since it involves
changing many parts in the amplifier section.
Also many parts must be added, some parts removed, and still other
parts such as resistors and diodes may need to be changed to different
components altogether. The stereo TV probably uses the same tuner, but
may need changes in the IF module too. Also the stereo TV may use a
different microprocessor so it knows how to use the stereo components as
opposed to the mono set.
In addition, if you are adding input/output jacks that are not part of
the mono set's original circuit, careful attention must be paid to every
component that has to do with isolation of voltages/grounds from the
jacks. A missing or incorrect component could cause a shock hazard or
risk of damaging your equipment when different units are plugged into
each other.
To sum it up, anything is possible and it CAN BE DONE. However it is
not cost effecive to convert a mono TV to stereo, even when there were
mono and stereo versions of the same TV available. As far as safety -
one misplaced or forgotten component would probably cause a catastrophic
failure of the whole TV.
Good luck on the IF module repair. You should have no problem.

I used to do this by using a stereo VCR or cable box for the audio portion,
no reason to muck with the TV itself.

Agreed; Jim:
Not only is this beyond the scope of the average tech but the cost would be
prohibitive on a 20" tele!. Drop the quid on a new tv or a cheap stereo vcr
and feed theoutputs to your surround sound amp. Cheers
