Jeff;
I believe that tuner uses a Programmable Phase Lock Loop IC.
It sits inside the tuner on a little sub-board.
It's a little tricky to replace but the second one will be easier.
It uses a SDA3202-2...your supplier will have the SDA3412, (good sub) or
use NTE7108. I have a PDF picture I took of the IC if you want me to
send it to you. The IC is about 6 to 8 $$.
You have to be sure not to heat up the little surface mount caps
and resistor (3). But it's relatively easy with a pencil iron.

Maybe you have a bad tuner, there is an ic inside the tuner
that usually goes bad, do not remember exactly, buy you
can send it to Tip Top for just 27 bucks
