It's your nickel, keep talking!!!

TV tuners are very difficult and very precise to troubleshoot. You could
remove the tuner, open it, and see if there are any cold solder connections
inside. It is possible that when soldering to some of the circuits, they can
get put out of alignment.

Without the proper equipment, and training, TV tuners are not something you
can easily service. Normally, the tuner is replaced as a module in the TV
set because of cost efficiency. Your tuner should still be available from
any Sony parts dealer.

I have a Sony KV-20TS27 trinitron TV, made in February 1992. It
displays UHF channels and the composite video fine, but doesn't display
VHF channels. Actually, it seems to display them intermittently;
haven't tested it thoroughly, but it seems that the VHF channels work
when the TV has been running for a while and heated up.

Is this a VHF tuner failure? How can I fix it myself? Perhaps something
as simple as a failed solder joint?

Thanks!
