Default Sony KV-27V36 has weird PIP issue.

This Sony KV-27V36 was working fine until about an hour ago. When I
turned on the PIP, it initially looked fine. Then I did a few
exchanges of channels from the small window to the big window. I
noticed the smaller window was showing just static. I thought the
cable had gone out for that station because the larger window was
still showing a clear picture. I hit the switch button again and the
problem still stayed with the smaller window. So now I know that
it's not the cable. There are only two choices in the setup menu
(not talking about the service menu) for cable channel select. They
are "on" or "off" and it's set to "on." To summarize, all the
channels work properly when the PIP is not active or if the PIP is
active and you're looking at the larger window. The smaller PIP
window will work fine until you reach channel 48. From channel 49
and above, it's all static. I'm fairly certain that the way the two
tuners operate is that they each stay on the same station when you
hit the switch button. All that changes is where the pictures are
displayed. Is that correct? If not, it would make sense that one of
the tuners is having tuning issues though I'm not sure what's so
special about channels 48 and above. The information I've researched
doesn't show those two channels (48 and 49) are situated on
different bands. Any ideas? Thanks for your reply.

I would say it is the tuner itself. Might respond favorably to
resoldering...

Used to see lots of problems like this.

Hi Mark,

Here I thought I would never again have the pleasure of resoldering a Sony
tuner/IF module. (-:

Thanks for your reply.
