Jack,

You are unable to describe your problem in the detail necessary to allow
anyone to guess at a cause.
You need to find someone who likes playing with electroics. There are
usually a few of these in any high school. Ask around until you find one or
two. Get them to help you.
They'll probably want the schematic. If it's not in the owners manual
you'll probably need to buy one.
