TRS-80 video synch chaos

I've got a TRS-80 Model I that MOSTLY works (I typed in a program to fill
the screen with characters and the screen did fill up) except for the
video synchronization.

Characters lean to the right, and the display moves all over the screen.
Usually the motion is quickly to the left while also moving upward, though
sometimes it stabalizes and just moves upward.

Is there an adjustment to control this somewhere?

The machine is in beautiful physical shape - it looks unused. There's
even a sticker still on it that is stuck to the expansion port's trapdoor
and sticks also to the machine's case. And the warrantee seal hasn't been
broken yet.
