Hi all,

I am writing from India and think you guys may help me. I
have a Sony 21" KV-K21MF1 TV set. The set has some
problems related to poor cable/antenna reception and
bad sound at times. There is a loud buzz in the TV and
sometimes the channels are in color and sometimes they
turn black and white. Normally on most of the channels
the reception is without color. When I change the
band, the picture comes colored, but the sound is
bad.

However, the TV works perfectly fine with VCD/DVD,
with full colors and oK sound. Sometimes the sound
gets distorted, and when it is switched on again it
gets good. However, after a couple of minutes, the
sound sometimes again gets distorted.

I took the TV to an Authorised Sony repair centre and they told me
that there is a problem with the IF board (block),
which is quite costly. What I gather from reading your
articles is that usually the problems are due to
improper soldering. Can u tell me whether this is the
case with my TV as well..

Looking forward to a help from you.

Thanks,
Nitin
