Default JVC TV - horizonal lines at bottom of screen

rob77:
This problem you are seeing is most likely NOT a "loose vertical ic
connection" and is probably NOT going to be solved by "applying a little bit
of solder" ..... More than likely, as others that have replied to your
original post have indicated, the problem is caused by faulty and/or high
ESR electrolytics in and around the vertical deflection circuitry. Not a
difficult or expensive repair at a shop but not necessarily a do it yourself
job for a rank novice..... particularly since televisions can pose a
dangerous electrical shock hazard even when unplugged from the AC power.
TAKE it to a shop for at the very least a repair cost estimate so you can
make an intelligent repair decision with facts instead of Internet guesses.

I was told the problem is quite possibly a loose vertical ic connection,
spoke with two people with similar models who fixed it by applying a
little bit of solder.... since I have nothing to lose there, figured
I'd give it a shot. But how to figure out which part that is once the
tv's opened up? Are there any telltale signs I should look for?

It is best to indicate the manufacture name and model number.

In a general context, troubleshoot for thermo sensitive capacitors in
the vertical deflection amplifier section. It is also possible
because
of the age of your set, there are a fair number of capacitors that
are
going high in ESR, and will eventually cause other types of failures.
