My Costa Rican neighbor needs a schematic for my Panosonic TV to do
some minor repairs...the problem is when the TV is turned on, there is
a line across the middle of the screen,,and when you hit the TV it
usually disappears and the picture then comes on the screen...any
thoughts what might be the problem,,(loose connection somewhere) and
where can I download a schematic?

You dont need a schematic for that fault
just resolder the Vertical Output IC usually
LAxxxx close to the leads that go to the yoke.
